XFX Black Edition 850w ATX PSU
Introduction & Specs
Published: 12th October 2009 | Source: XFX | Price: £159 |
Introduction
THIS image is something most of us will have undoubtedly seen floating around the net for quite some time now. It caused quite a stir over on our forums, and undoubtedly other enthusiast forums all around the globe too. First shown off at Computex earlier this year and only fully confirmed for release a short while ago, XFX's first foray into the PSU market was obviously never going to be a quiet one.However, GPU manufacturers entering the PSU market is by no means a new thing. Back in June I had the opportunity of reviewing a 1200w unit from BFG which failed to impress due to poor performance and quality control issues. Furthermore, Sapphire Technology also recently announced their own PSU range which we already have their 1250w model in the labs for testing. Add to this the already well established list of PSU manufacturers such as OCZ, Corsair, Enermax, Be-Quiet..etc..etc..etc and any manufacturer wanting to muscle in on the power supply market is going to have a hard time finding their feet unless they've got something quite special.
XFX of course have pulled out the big guns and launched their first PSU as part of the "Black Edition" range which traditionally only encompassed their high-end pre-overclocked graphics cards. The 850w unit sports a green and black attire that will of course look right at home inside any PC kitted out with an XFX nVidia GPU or Motherboard, but let's start by checking out the specs to see if XFX have done their homework:

The Black Edition 850w boasts up to 90% efficiency with an 80PLUS Silver rating, a single 12v rail, Japanese 105°C capacitors, +3.3v/+5v DC-DC modules with solid state caps and a 135mm fan. Naturally support for multiple high-end graphics cards is also on the list, but we're not going to find out exactly how many PCI-E connectors are included until we take a closer look over the next few pages.
XFX have also included a 5yr warranty which should go down well with those of us who keep their hardware for longer than a few months before upgrading. However, do note that you need to register the product in order to take advantage of this, otherwise you'll be stuck with a fairly basic 1yr warranty and a dent in your forehead from the repeated *facepalm* should the PSU go belly up after this time.
| XFX Black Edition 850w Rail Layout | ||||||||||
| DC Output | +3.3V | +5V | +12V1 | +12V2 | +12V3 | +12V4 | +12V5 | +12V6 | -12V | +5VSB |
| 24A | 30A | 70A | - | - | - | - | - | 0.8A | 3A | |
| Max Power | 150W | 840W | 9.6W | 15W | ||||||
| 850W | ||||||||||
Power output is fairly common for an enthusiast orientated PSU with almost all of the 850W output being available on a single 12v rail should it be required. As XFX have already said, this eliminates any potential issue where a high current +12v device (such as a graphics card) could trip the OCP (Over Current Protection) on a PSU with say 6 rails rated at 20A each. Some urban myth surrounds this idea though, as most PSU's with 'multiple rails' tend to have each of the PCI-E connectors attached to different rails thereby avoiding this issue entirely.
Anyway, it's fair to say from the specs list at least that XFX have put together a PSU that should have most enthusiasts putting their hands in their pockets reaching for their..ahem...wallets right now. So let's press on with the rest of the review to see if it lives up to our expectations.

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.Quote

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

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.Quote

I didn't think of it like that, suppose you're right.Quote
Something I also thought about is if its like that new, what happens overtime, will it get worse? What happens if theres a storm or something the overcurrent not working properly could be a very bad thing imhoQuote
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.Quote

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 wayQuote

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 QuoteThe point is mate, the over current is a big fail in that PSU, and its a massive problem.Quote

Gah! I will give in. CBB to continue this discussion lol.Quote
Have OC3D tried to contact XFX yet?Quote
This was the 2nd PSU so yes, and we have spoken to them tonight. Does seem to be a big concern for them tbh.Quote

Think it will be getting discussed with the oem manufacturerQuote
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...Quote

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.Quote

The offer has been sent. Plenty of people think it would be a very good idea to find out if these are indeed safe.Quote

By the way, how can you explain that in this review they pulled 996.8w from it without any issue?
QuoteThe 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 didnt burn or explode.

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.Quote

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.
QuoteThis 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.Quote

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.Quote

, 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'QuoteWe 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.Quote
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.Quote

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.Quote
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.Quote

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

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*Quote

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.Quote
Thats not rma thats just plain refund - distance selling rules and allQuote
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 repliesQuote

[ 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.Quote
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.Quote

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.Quote

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 910WQuote

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

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!!Quote

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 Ill go with the OCZ. Unless There is a reason I'm not aware of to reconsider. Thanks for all the Info though.Quote
