XFX Black Edition 850w ATX PSU

Packaging & Appearance

Packaging & Appearance
 
Starting off with the graphical design of the packaging, the word 'striking' really does not do any justice. XFX have combined a dark 'DOOM-like' grey and black mechanical design along with bright retina burning dayglow green highlights. Aside from the large "850" text and SLI/80PLUS certification stickers there really is very little information on the front of the box, but with a design like this it is highly unlikely that any enthusiast or gamer could casually walk on by without feeling the urge to pick the box up and find out exactly what is inside.

The bulk of the information has been placed on both the back and sides of the box, with the feature list and rail distribution charts seen back on the previous page making a reappearance. A glossy picture of the PSU is also printed at the back of the box, but to be honest I think that XFX have missed a trick by not incorporating some kind of window into the packaging so that potential buyers can get a good look at the actual unit contained within.

Sliding off the outer cardboard layer reveals a two-tiered box design with the top box (modular cables) interlocking into the bottom box (PSU) with some rather simple cardboard tabs. Opening the larger of the two boxes gives you your first glimpse of the actual PSU with XFX keen to show off the spider web style fan grill and fluorescent green 135mm fan through the middle of two black cardboard flaps. Yet another smaller box can also be found beneath one of the flaps, which is beginning to make me think that XFX borrowed their packaging design from a matryoshka doll!
 
Slightly disappointing is that XFX haven't placed the PSU inside any kind of protective bag, instead leaving it to ride bareback against the cardboard. Hopefully this shouldn't be a problem as the paint on the PSU feels quite hard wearing, but never less there's nothing worse than having your latest purchase arrive at your door in anything less than pristine condition, so maybe the lack of protection could be addressed.
 
Included in the box is a fairly basic set of accessories. Your get both a UK and Euro mains cable, a set of case screws and a rather snazzy canvas pouch full of modular cables. Some velcro cable ties would have been nice, but I'm not going to moan.

Moving on to the appearance now and you'd be forgiven for thinking that the unit had fallen off the back of a UFO. XFX really have gone all-out to make this PSU look as extraordinary as possible while still obviously retaining the standard ATX form factor. The aforementioned spider-web style fan grill is obviously the most striking of changes and coupled with the green fan blades, goes a very long way to separating it from the rest of the crowd. A cog-like pattern has also been punched into the top casing of the unit, which joins with three 'valleys' that run down the modular connector area.
 
The rear of the unit is fairly standard with a square exhaust grill dominating most of the available space. Given the look of the rest of the unit I was half hoping that XFX may have at least installed a couple of green status LED's just for 'extra effect' but alas the only customisation in this area is the vertically mounted XFX logo sticker.

Around the front of the unit are a total of eight PCI-E style modular connectors all finished in lime green plastic. Although this looks immensely good, it is slightly worrying to think that someone may try to force one of the 6-Pin connectors used for the SATA/Molex cables into one of the 8-Pin graphics card connectors thus delivering +12v down the +3.3v and +5v wires. Not that I'd want to spoil the style of the unit, but maybe some kind of visual aid would have been useful to help differentiate the two styles of connector.
 
Now let's move on to the next page and take a look at the cables and PSU internals in more detail...

Have to say that video is great for suspense! Rather shocking for such a big brand though. Be interesting to see if they say anything.

Still think that people will buy this no matter what just because it looks good and has XFX written on it.

ok is it just me or does the top of that psu look amazing?

the bang want that big in the video tho =\ i was expecting the camera to wobble and someone nearly cacking them self

other than that good review from the quick scim i gave it for now.

You can always turn up your volume for a more authentic reproduction. Unfortunately all the "cacking" was done when the first unit went bang right as I had my ear pressed against it while listening to the fan noise.

Couple of cracks and he doesn't jump, flinch, move, gasp... nothing.

If BFG and XFX have taught us anything, and to a certain extent the woeful air performance on Corsairs 800D, it's that companies should stick to doing what they do best.

Yep. So long as you don't exceed the rated output then there should be absolutely no problems. The MAX Load test is just there to test the capabilities of the PSU (much like CPU overclocking) and the safety features of the unit. I also test every PSU for SCP - Short Circuit Protection (which is kinda like OCP anyway) to ensure that they power off when a connector is shorted.

Unless somebody tests thse features everyone just takes for granted that they work until one day their PSU turns into an arc welder

Nice review Jim, good to see a bang finally

I wouldn't say it's a problem not being able to deliver 120w over the rated load, as it's not rated as a 970w unit...

Not exactly, but then you could apply that logic to a car. What would happen if Ford sold a car that officially had a top speed of 150mph on paper, but down the motor way you got it up to 165mph and the wheels fell off.

IMO you either limit the speed to what is on the paper, or make sure it can cope with going that little bit faster without falling apart.

First of all, I doubt 120 watts is a "little bit" more.

Secondly, unless you were stupid enough to SLI two/three cards that require more than 850 watts, then you deserve to have your PSU go boom. Common sense peoples.

Again, this is another form of stupidity. If the car states that it can go up to 150mph, why would anyone be stupid enough to try and go over it. lol

I don't necessarily recall any event in the past that resulted in the some for of computer hardware suddenly spiking up its energy draw up by 120 watts.

Actualy Zak 120watts is nothing for a high end PSU, the Corsair 750w does near on 1000w within ATX spec in the hotbox and the 1000w has been tested again by us @ 1480w.

Read all the PSU tests and we test them all the same, this is the first (pair) of PSU's we have had in that have died in this way

Are we heading the way of a 'natural selection' argument again If safety features are used then they must work IMO. No point in having railings on the edge of a cliff if they are stuck there with blutack

If you are an enthusiast who wishes to overclock, then I would recommend that you buy yourself a better, more powerful PSU.

That's another thing I don't get... This PSU is nothing more than a Seasonic M12D 850w with even better voltage regulation. So, how can Seasonic build a PSU with crappy OCP? It's Seasonic for crying out loud...

What Tom is trying to imply is that yes, it would seem that this particular model does have OCP issues. Every other PSU I've performed the "MAX Load" test on I could keep tripping OCP until the cows come home without any ill effect. However, just a couple of trips of OCP on this unit and *bang*.

Unfortunately when we tested the M12D, the max load test wasn't part of the procedure, but given that they are the same unit essentially I'd be willing to place a bet that they have the same issue.

You should try to get a hold of one, M12D, and test it again. If this is confirmed it is indeed a big design flaw...

Second that. They should really sent you one (make it two) for re-testing.

By the way, how can you explain that in this review they pulled 996.8w from it without any issue?

The idea behind of overload tests is to see if the power supply will burn/explode and see if the protections from the power supply are working correctly. This power supply didnít burn or explode.

Interesting. I would like to know how long they actually maintained that load for. During my tests of the unit it did indeed hold up just shy of 1000w for about 1-2 minutes before powering off. At this point I started to lower the +12v load until I could find a load that it was capable of holding for more than 10 minutes solid. It was during this process that the 'explosion' occured.

Although I don't want to knock anyone's testing procedures, I know all too well how tempting it is to run a test at a certain load for just enough time to gather the results before moving on. Especially when you get to 1000w, the heat from the PSU and load testing equipment can get a bit much - not to mention damage to your load equipment if it is not properly cooled.

Well it depends on how much the person knows about XFX.

If a person is new to all of this, then he probably would be disgusted at XFX on the whole since that person wouldn't really know anything about them previously.

This is really unfortunate. I had this PSU on order and cancelled it based on this review

I did a decent amount of research in coming to my conclusion to order it in the first place. Even though i may never create the circumstance that this would take place i still would not feel comfortable leaving my computer on while i am not at home.

I would gladly support a company that takes a boring little box and turns it into something that i would find next to a Strog's corpse and has the same or better quality as other current power supplies. I'd even be willing to spend the extra $20-$30 for it. Heck they are supposed to last 5 years right?

But alas... i cancelled my order and got an HX1000w for $200 on sale.

Their lack of response to rectify this matter didn't help their cause in my decision.

Finally got around to reading this.

Was wondering why the thread had 4 pages...

Tis a shame really but after reading the comments it isn't likely to get to those levels in normal use.

The problem comes though if you're say drawing 700W during some gaming or something and you get a nice juicy power surge or as Tom previously mentioned, a lightning strike. Pretty sure that could send up to those levels and beyond. If the protections aren't functioning properly at that point, then POP.

Regarding the XFX 850w Black Edition PSU which the above quote is aimed at, did any of you (as in tinytomlogan or Jim) manage to find out exactly what XFX had to say about this OR what they planned to do about it (if anything?) and did you or have you/are you planning on having them send you another one of these PSU's in the near future? Because I'm very concerned about this as I had to recently RMA a Corsair TX 850 watt psu despite it getting good reviews, because there was a fault with it so I decided against getting a replacement and instead went for the XFX 850 watt psu after reading some good reviews on it, and before I read the review on this site I went and purchased it (and it got to the stage where I couldn't cancel it as I chose next day delivery) it'll be here today Saturday the 7th of November, but what worries me and would have made me cancel the order is what happened in your review which you have mentioned has NEVER happened with any other PSU's you've tested.

Question is, has it been a big enough concern to them? And I'm also wondering if they've done any testing of their own? And if they've fixed this problem?

As above, I really hope they have fixed this problem, and I'd appreciate if someone could reply to this thread again (possibly Jim or tinytomlogan) and see if any progress might have been made, because I've paid a massive amount for this PSU (well massive for me) it cost me £145 inc delivery and I won't be happy if it's second rate goods and the OCP doesn't work as it should, say when it's lightning outside and there might be a surge , I do have my PC connected to a surge protector but that's not the point, for such an expensive PSU I would expect it to be flawless, so what should I do now, leave it boxed up and send it straight back OR keep it and hope for the best? As I'm really sick of all the hassle of having to rma computer components/parts that don't work as they should lol.

I look forward to some response as trawling the internet I have found no other news about this PSU being 'Fixed'

We have heard nothing back from eitherside yet, I will try and get some information next week for you dude. All we know for now is it was a big concern, and XFX had decided to do their own testing with Seasonic the OEM manufacturer.

In addition to what Tom said, various sources have told me that this PSU (and indeed a lot of other single rail PSU's) do not have OCP on the +12v rail at all.

To break it down, OCP is what is often used to split the output of the 12v transformer in PSU's that have more than one rail. For example, say you have a PSU that has a single 12v transformer, but on the spec shets it says that it has 4x 12v rails all rated at 18A. This is the manufacturer using Over Current Protection to 'virtually' split that single transformer into four rails.

However, even if a PSU doesn't have OCP it will also have OPP (Over Power Protection). OPP performs a very similar function in that it is supposed to shut down the PSU before an overload occurs. The only caveat is that it is often on the primary side (mains voltage) side of the PSU and therefore isn't as accurate as OCP in measuring just how overloaded the PSU is.

So basically to summarise, the XFX 850w DOES NOT have OCP on the +12v rail AT ALL. What killed the PSU in our testing was poorly implimented OPP protection and components (schottky diode in this case) that just couldnt take the additional load.

The reason it hasn't happened to any single rail PSU's we've tested before is that they have all had more finely tuned OPP protection, better components and better OTP (Over Temperature Protection) on the components that are likely to overheat and exploded.

So what would you recommend I do on a professional level? Send the XFX back to ebuyer for a full refund and try to find a psu that's more stable or will it actually be okay, as in how likely is it I would have a MAJOR problem if it was thundering/lightning outside if the protection is a bit shoddy!

And is there even a chance it's been fixed at all??

And I appreciate you saying you'll try to find out more info for me hope they get in touch soon.

A lightning strike doesn't really come into the equation with the problems we highlighted. Any surge via your mains should be stopped by your house breakers (and if you have an expensive PC - I hope you've also got a surge protector too!). OCP/OPP can't save you here.

The only time that using the XFX PSU could _potentially_ be harmful to your PC is if you run it above 850w. So for example in 6 months if you decide to go Tri-SLI without thinking about the max output of your PSU, this is when you could be at risk.

07-11-2009, 12:03:20

Freak
As Jim said it only blew when pushed. I dont think with a 'normal' set up you would get it to go pop.

So i would very much doubt it will go bang.

But as you bough it on the internetz then you are able to send it back and get a full refund - as long as its in 14 (i think its 14) days.

But honestly I wouldnt bother.

The spec of my PC is below,

Case = Antec 300

Case fans = 2 120mm fans at the front of my case

Memory = Corsair 4gb XMS3 DDR3 1333 mhz ram

Motherboard = Gigabyte P55-UD3

CPU = Intel Core i7 860 @ 2.80 ghz

Graphics Card = NVIDIA gtx 275 896mb ram

Hard Disks = 120gb Seagata SATA/320gb Hitachi SATA II/1tb Hitachi SATA II

Optical Drives = Samsung DVD-Rom Drive and a Pioneer DVD-RW Drive both SATA

And I've got no plans on going tri-sli anytime in the next 6 months or even after that at the moment.

But what's driving me nuts is the fact that if I did want to I wouldn't be able to, or that's what I gathered when you said I may be at risk, because I would have thought if I wanted to I should have the option without having to worry about it blowing up on me lol.

How much wattage does my current spec take/need then?

P.S) This is the surge protector I have my PC connected to hxxp://img20.imageshack.us/img20/398/1002880x.jpg couldn't post this as an image because not allowed to post url's to other sites unless 15 posts have been made

That system will be fine on an 850w dude tbh, you wont be getting near 750w even on 100% tbh.

07-11-2009, 14:09:34

Ravenheart
So should I just keep it then? The only issue I have is if I wanted to go sli or even tri-sli in the future i'd be worried it would go bang.

Sooooo big question is do I keep it or rma it and get one that I know won't blow up on me now or in the future.

P.S) I just did the Power Supply Calculator here hxxp://extreme.outervision.com/PSUEngine and it reckons I'd only need 334 watts for all of the above, that can't be right surely! Unless you're supposed to double whatever it tells you?

07-11-2009, 15:31:53

tinytomlogan
Did you run the calculator at 100%?

Youd be suprised tbh dude, a 600w psu would probs be ok for your system atm.

Im not sure if you could rma without it being broken tbh, even then most places would be inclinedto send an identicle replacement.

The issue we had with the PSU's was they didnt cut out, so unless you are planning on building an insane gaming machine you should be fine. Later down the line if you decide to go SLI chances are youll change other parts anyways, I know I do *blush*

I've been back and ran the calculator at 100% and it says Recommended PSU Wattage: 391 watts

I did have a ThermalTake 600 Watt PSU before this one and just upgraded it because of getting a new cpu/ram/mobo, the one in my current spec.

Can't say I'm thinking of building an insane gaming machine but as mentioned previously I should have the option to considering the price of the xfx psu!, the reason I spent so much on the psu as well (although I get your point about you changing your parts) is that I thought spend the money on a decent psu now so I don't have to in the future.

And the fact that I always sell on the parts I'm upgrading to put some money towards the upgrade, I sold the ThermalTake 600 watt psu for £47 before I bought the Corsair I had originally.

As for rma'ing, you are able to rma if you've had the psu less than 7 days and I've only had the xfx one for 1 day and not even put it in my machine yet.

Thats not rma thats just plain refund - distance selling rules and all

That's true but try telling that to the companies components are bought off, I have to rma the bl**dy thing just to get a refund.

Which yeah technically is only a refund, but companies like to take the long way round (I guess) as it has to be rma'd first which is the point I was trying to make, even though technically it's not an rma because i'm returning it to the reseller not the manufacturer of the psu.

Thanks for your replies

[ 7/11/2009 8:02:39 PM] I have read that when tested this power supply blew up and that it was a major issue for you at the time of the review and that you were looking into it! The review was read on overclock3d.net and has been discussed at length here hxxp://forum.overclock3d.net/showthread.php?p=354173#post354173 Can someone please get back to me and let me know what has been done about the stability of this psu (to stop further potential problems) and if the problemthat caused the psu to blow up has now been rectified?

[SHAUN_T 9/11/2009 11:38:10 AM] Hi, thanks for your messages. Please note, it was the weekend when you posted your support ticket, therefore there were no technicians available to answer your question at the time. There have been many XFX PSUs sold recently and the customers have had no issues whatsoever, so there are no known faults or issues with the product. Have you tried installing it into your system? If you have any problems with it, please do let us know. Kind regards, Shaun.

[ 9/11/2009 1:28:23 PM] No I haven`t tried installing it in my system as yet because of the review I read, and i`m not sure whether or not to just rma it for a refund because, now I`m not sure if they deliberately overstressed the psu or not but they are claiming that the protection that`s supposed to be built into the psu to stop it blowing up or exploding only kicked in once and the 2nd time it blew up and they claim it happened to 2 out of 2 of the psu`s, can you do me a favour and read the review via the link I posted then report back to me what you make of it so I can have some sort of peace of mind and a genuine honest opinion from yourself. The review is located here hxxp://forum.overclock3d.net/showthread.php?p=354173#post354173 Thank you

[SHAUN_T 9/11/2009 2:54:49 PM] Hi, thanks for your message. Like I said, there are no common faults/batch issues etc with the XFX PSUs, we have had many customers using them without a problem. I have scanned over the review vaguely but we cannot pass much comment as we do not know the system setup etc etc. Why they had these problems I do not know, but there isnt much more I can do than to assure you there are no problems with the PSUs. Kind regards, Shaun.

[ 9/11/2009 3:30:14 PM] So is it wrong to assume that you knew about this issue because they mentioned they had informed you (well not you personally) but XFX about this issue and that you knew about it, and that XFX were very concerned about this and were going to run some tests to verify there was no problem because you seem to be side stepping the issue completely instead of assuring me the units had been tested after that review and that those 2 out of 2 units must have had a fault. You have done nothing to ease my mind as you have clearly stated that there are no common faults with xfx psu`s, but how would you know if you hadn`t done some tests after that review quite clearly stated you had been informed and they had no response from xfx regarding the issue. Thanks for replying.

[SHAUN_T 10/11/2009 11:36:55 AM] Hi, thanks for your message. If there was an issue with the PSUs, for example, a batch issue they would have been recalled. Obviously, other users have had no issues with this product, and we have not had any support tickets complaining about anything. Therefore, as far as we know there are no problems with these PSUs. If you do not wish to use the PSU, it may be best for you to return it to your reseller whilst you only bought it 4 days ago. Kind regards, Shaun.

[ 10/11/2009 12:26:07 PM] I just figured if they did let you know then maybe you would have done your own tests to either substantiate there claims or prove them to be false, I haven`t made my mind up what I`m going to yet but I do appreciate your replies and you seem to have been fairly honest in your responses. Thank you.

[SHAUN_T 10/11/2009 12:27:23 PM] Hi, thanks for your message. No problem, we`re not here to lie to you, so if you do have anymore questions or encounter any problems in the future, please let us know. Kind regards, Shaun.

whilst they are not lying, they are doing what all media people are trained to and only put forward arguments they appear to answer the question but are actually sidestepping. I have to say it was very interesting to read their response.

Seems that they would rather have people blown up before doing anything - which includeds tests themselves.

Frankly I am not surprised that XFX haven't received many customer complaints or particularly high fairlure rates. The Power Supply Unit should function up to and including the rated power output. Jim's testing has proven however that once pushed past it's limits the overvoltage protection is nigh on non existant and so the Black Edition 850W reacted in this way.

For a start, I can only think of a small list of typical system configurations that would even push a PSU to 850W let alone higher and so chances are (at this point in time) even those with the upper end systems aren't suffering from any problems. This however does change as time goes by. By nature, a PSU like any electronic device will degrade over time and in theory that threshold at which this unit will go bang will lower accordingly. Even if I'm being pedantic because the rate of degradation could be argued to be low, it's the principle of it. Would you expect a £160 unit to be capable of shutting itself down before it causes itself or other components damage? Based on Jim's testing it seems as though it cannot.

Whether your system commands 850W and over is irrelevent. If the unit cannot save itself once pushed too far, why settle for it? I don't for a moment find this acceptable.

Those were my thoughts exactly. A PSU with this kind of price tag should not have this kind of failure. It's intolerable. That's why I returned my XFX 850w (without even using it once) and brought home a Corsair HX-750.

TBH I think you did the right thing, I love my HX850

I dont like the green fan , and the PSU case look strange ugly , and to be honest the modular feature is not necessary because I have a case with holes to hide the cables at the back of the mobo tray , this is the reason I bought my lovely PC Power & Cooling 910W

They are your own preferences mate.

I for one love the green fan, the PSU case and would love a modular PSU!

I think XFX are clearly denying the issue until enough genuine end-users have or complain about this problem, which could be a while.

It's a shame, as the PSU appears to be very good except for that, and the styling is different, and would undoubtedly sell well in the enthusiast market.

What would be best for XFX at this point would be for them to acknowledge the issue and offer customers an RMA for a revised model (if indeed one has been made) if they wish. This would save their reputation (in this new field to them) somewhat, and perhaps they will produce some more good quality PSUs in the future, instead of being forced out the market for a small issue. More competition is usually a good thing for us customers.

As it stands, I feel like the company is burying their head in the sand somewhat and sidestepping the issue as already said. This is pretty much what I would expect from a big company of their type, but they have an opportunity to now prove us wrong.

I do feel that the tech support chap was being honest though. As far as he knows there probably never was an issue brought to his attention, and he was just doing his job (correctly!).

All in all, I wouldn't buy one until this is addressed or recognised, as it gives me little faith in the brand, or indeed the RMA procedure (vital with PSUs in my experience). Swap it for a Corsair and you won't be disappointed (and I say that after having two fail on me, but that's a different story).

Thank you TTL/OC3D,
can't say it enough. This was a very important review for me and I suspect many others who were considering purchasing this PSU. While I'm disappointed about the fail. I'd much rather discover it this way. I hope XFX will take a long look in the mirror and decide to resolve this matter. Although, judging by their correspondence it doesn't look hopeful. Thanks again for this piece Tom and for all you do to keep us all informed.

Apercus out!!

Just so you know, the new XFX Pro series are very good (rebranded Seasonics) so don't confuse them with these old models from a few years ago and let that put you off the Pro series because you wont be disappointed with the new range!

Thanks Chuckers, I have the XFX P1-850B-BEFX 850W 80 PLUS GOLD Certified Full Modular Active PFC Power Supply on hold at Newegg, great price to $101.00 after 20% discount and $15.00 rebate. So It's either that or the OCZ Z Series OCZZ850M 850W 80 PLUS GOLD Certified Modular Active PFC Power Supply about $80.00 after $30.00 rebate and $30.00 promo. Great prices just when I need a power supply. I just need to choose one. I think Iíll go with the OCZ. Unless There is a reason I'm not aware of to reconsider. Thanks for all the Info though.

Go for the XFX, they are much better quality than the OCZ units. It's not to say that every OCZ unit is bad it's just alot of their products are poor quality and dont have the longevity that the Seasonic XFX's have so people tend to steer clear of OCZ as a whole.

(I know I have an OCZ psu in my sig but I'm changing that in the next week or so! )

Hi Chuckers,
So do I my OCZ is a 650w, but thanks to all the good advice Iíll be swapping mine out for the XFX PRO850w at a great price.

Thanks again.
