Specs

Efficiency

Noise Level

The HX620 appears to have some very impressive specifications including ~85% efficiency, noise levels of around 35dbA under 100% load and triple +12v rails rated at 18 amps each. Corsair also claims that each of the +12v rails are able to share power, thus meaning that if any one of the 3 rails becomes overloaded, one of the other rails will be able to assist.

"Corsair have made a brave branch out from the memory market into their own line of PSU's. Today I'll be putting their HX620 through its paces to see if it lives up to Corsairs reputation for high performance components."

Had a quick flick though. Another good job Mr XMS.

Seems very pricy to me though.

"For a ~600w unit the sum of £96 (over at Scan.co.uk) may seem a little higher than most other competing products, however as the saying goes - "You get what you pay for", and this is certainly true for the HX620."

I compare it to the Enermax Liberty as I've had the 620 and currently have the Corsair 620, to me the Corsair is a lot better the cable system is much more usable and the noise is in another league I honestly cannot hear it on idle load unless I put my ear 8" away from it, even under load it remains the quietest PSU I've "never heard".

Another thing to add is the 5 year warranty has to be worth something extra, I rate it very highly and I have had or built PC's for other people dozens of different PSU's.

PS Very nice review as usual XMS.

Great review Jim. And I must say that is a beastly ass PSU. I'm actually going to look at putting one of these babies in my rig... I absolutely love the cables that they've used, those are just stellar. Off to find one in the USA

Hi Frag, I'm sure you will be pleased with it the cables are a nice touch if you like them, they are slightly stiff but they are easy to bend and move around will make your case look great.

Another great feature is it's quiet operation, in my humble opinion only the Etasis 750 850 Sliverstone series are better, the downfall of those for me are the noise and not being modular.

I hope when you get yours your as pleased as I am with mine.

Thanks! I'm sure I'll be a happy camper once I find one I'm not all too terribly worried about the noise levels as I've got a couple of noisy 120's inside the Vapo case which will probably outnoise the PSU, hehe. I am looking quite hard @ the SS psu's as well, but I'm really really liking the cables they've used on the Corsair.

performance looks great but im not too keen on the looks. looks more like a server psu than a high end desktop job. nice review either way

28-11-2006, 08:49:41

FragTek
The looks are perfect for my case... Black & red all the way. Black mobo, red CCFL's, black Vapo hose. I think it would look wicked-sick in my case. I think that is going to vary by user however, such is llwyds case.

Thanks for the offer! I'm sure I'll be able to find one when the time comes, don't think i wanna upgrade right this minute.

It looks abit sexy!

Same about the price..

Raven

During the +12v load testing, each of Corsair's three rails (rated at 18amps) were placed under a total load of 30 amps. As a result of this, each rail produced the same voltage output results across the board and therefore only necessitated a single graph as shown above.

and the reason for this is that it has 1 big 12v rail and not 3 different 12v rails.

all 3 rails gets their power from a single transformer and the rails are not differented on pcb level but more on the wire level.

one reviewer asked corsair about this and received this explanation.

For this, Corsair sent us this explanation: “Since our PSU follows the latest Intel design spec, it is consider an UL Level 6 design, which means there is no 240VA limitation on the +12V rails. In addition, all the +12V rails are drawing from single transformer, the rail separation is not done on the PCB side, but on the wiring side. Therefore the +12V1 and +12V2 you see on the PCB doesn't really mean anything.”

another reviewer loaded one single rail with 40a and didnt notice any drop in V or any other problems such as overcurrent shutoff.

Mr. Smith
This is an amazing PSU!

Although it is not a new product it was showcased at CeBIT 07 powering a monster system - a watercooled, overclocked quad FX with 8800GTS SLi, 4gb of OC'd ram and a 150gb raptor plus the usal bits and pieces...

All on 620w!

Link I know it's the Inq but it is true!

I'm looking at getting a Lian Li V1000B soon and was wondering if anyone has tried fitting a Corsair HX620 in one of these. I know from the specs that the PSU is physically small enough to fit, but is there enough space for the modular connectors and cables to be routed?

Anyone tried or seen this configuration, thanks for any info.

For those interested im looking at making something along the lines of:

Lian-Li V1000B

Corsair HX620W

Core 2 Duo E6600

Thermalright U-120 Extreme

Asus Striker Extreme

2Gb Corsair dominator

XFX 8800GTX 768MB

X-Fi Elite Pro

Adaptec 3805 (8chan PCIe raid)

4x 500GB Seagate 7200.10 (Raid 5)

1x 150 GB Raptor

Dell 2407WFP

I can't imagine you'd have any problems at all really. The PSU is a fairly standard size and the modular connectors only add a couple of mm to the size. In fact, they are probably the smallest footprint modular connectors of almost all modular PSU's

09-07-2007, 09:10:08

Nemesis
Indeed, i don't expect there to be any problem really, just want to be sure. I know the V1000 is notorius for PSU fit problems as it has an aluminium wall between PSU and HDD enclosures that makes any oversized PSU a no. Just wanted to check that the extra size added by the modular cable connectors wasn't going to push me just over size

Get the dremel out if there is any issues.

Nice spec you got there btw, 2TB

Hehe, would rather not have to take a dremel to it if i can help it

Last case was a custom modded H2O cooled Lian Li PC70 with a 120x240 radiator modded into the top panel, self built custom FanBus, window, Cathodes etc. Hoping to keep this one nice and plain and simple as I dont really have the time and workshop space these days to do this kind of work

Well 1.5Tb once you take raid into account (less due to native drive sizes etc)

Should be about 1.6Tb once you add on the 150Gb raptor system drive.

Last system I have was built some time ago now:

Barton 3000

1Gb Ram

Ati 9800pro

640Gb Hdd

So its about time I treated myself .

Probably be another month till I have the spending money together to pull this off, so will likely have changed a bit by then anyway.

^^ iv got two sitting next to me waiting for the rest of the pc!!! (they were on a deal at komplett ^^)

22-08-2007, 11:38:16

Why how much were they, how come you purchased two?

22-08-2007, 11:41:19

Azreil_2
£80 each, and i got two as im building my own rig this/next week plus my brothers (and another two within the month, if not at the same time lol)

Something to consider when picking up a Corsair PSU:

The VX-550, and the TX-750 are not Seasonic built, they are build by Channel Well(CWT). They seem to be just as good quality, although they are not as quiet as the Seasonic built models(VX-450, HX-520, HX-620 and TX-650)
