• Guaranteed compatibility with dual-GPU configurations.
• Double forward switching circuitry design offers high efficiency, up to 80% under wide load range.
• Active Power Factor Correction with PF value=0.99 provides clean and reliable power to your system.
• Universal AC input 90~264V automatically scans and detects the correct voltage. No more hassle of flipping that tiny red switch!
• Ultra quiet 120mm double ball-bearing fan delivers excellent airflow at an exceptionally low noise level by varying the RPM in response to temperature.
• Guaranteed to deliver rated specifications at 50ºC.
• Triple 12V Rails provide independent reliable power to the CPU, video card and other components with a combined rating of 50A (40A on 520W) maximum! Advanced circuitry design that automatically enables power sharing between the triple +12V rails in an event of overload on any single +12V rail.
• Powerful +5Vsb rail with 3A rating.
• Over Current/Voltage/Power Protection, Under Voltage Protection, and Short Circuit Protection provide maximum safety for your critical system components.
• 105ºC rated industrial grade capacitors provide uncompromised performance and reliability, delivering 4 times the lifespan of conventional 85ºC rated capacitors.
• Enhanced modular flexible cables enable easier cable routing and increased airflow in the system.
• Gold Plated connectors provide oxide free ultra low-resistance contact between the power supply and your critical components.
• 8 Serial ATA connectors (4 on 520W).
• Dimension: 5.9"(W) x 3.4"(H) X 5.9"(L) 150mm(W) x 86mm(H) x 150mm(L)
• MTBF: 100,000 Hours.
• Safety Approvals: UL, CUL, CE, CB, FCC Class B, TÜV, CCC, C-tick.



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.

Seems very pricy to me though.
Price?

I was looking for $$$.

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.

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.

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.

Canadian site, so you could pick it up pretty cheap

Same about the price..

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

.Nice spec you got there btw, 2TB

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.

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)
