OC3D Review: Corsair AX 1200w ATX PSU

I was lucky enough to see the results prior to it going live.

It is truly epic. With a price-tag to match. Ouch.

But clearly if you want the best...
 
I dont think its too bad, the aging HX1000w is still selling for £190, so for all that power and gold efficiency then I dont think its too bad. Just found it at scan for £246 now too.....
 
Am I the only one who finds 6 pcie connectors lacking? Corsair's own 850W unit has 6, which has 30% less power. Antec's 1200W has 8 and the OC edition has 12!

And, well, to the danger of 100A, we don't need to say anything, do we?

I cant say that I've heard any unusual noise from the unit. Obviously the PSU testing equipment creates quite a bit of noise its self, but normally PSU's that make high pitched noises stand out above the low-pitched hum of the fans.

As for the single 12v rail, I can see where you're coming from. However I've not heard of any cases where a failure of a single rail PSU was any more catastrophic than a multi-rail PSU. At the end of the day 1200w is 1200w. Even if its split cleverly by OCP, it still has the potential to go wrong. Unless a PSU is physically split (different transformers etc) then it's naive to assume multi-rail is safer.

I did also get a gut feeling that the AX1200 was safer than a lot of other units I've tested before. It handled overloading extremely well and shut down gracefully without me wincing and expecting a *bang*. That is just a gut feeling though.

I noticed it already and tell Corsair about it at their forum... But it seems after GTX480 hit the shelves everything we know about consumption become history :) So maybe they want to prevent trying to power quad SLI reducing connectors to 6 though...
 
@Jim

I worked as an elictician for a time, so my belly hurts a little (more) when I have to see those 100Amps...

Have you tested the short circuit protection?

As for electronics noise: I tested the Corsair AX1200 on my P4 testsystem (an old FSC D1520 with a 2GHz Celeron) and it had quite notacible electronics noise, haven't tested anything else, though...

@Kartoff

The problem is that the AX1200 hasn't enough modular connectors for more than 7 eight pin PCie connectors, 'cause they're shared with the EPS12V one...
 
I think there are enough place to put 2 more connectors for PCIe so total number will be 8 but they put only 6 and a label :)
 
The actual manufacturer of this unit is Flextronics. You know the guys that build videocards.

And what a unit it is. It's the first time since the Antec Signature 850 (a Delta built unit) that I am actually impressed. It looks well engineered, only good quality components used and VERY much attention and care to detail.

This is THE one PSU to have, one PSU to rule them all. Until someone makes a better one... lol.

I also like that they finally sorted out the Ultra patent on modular PSUs, and I see they are getting their license worth.

Anyone knows of another Flextronics PSU out there? Maybe a sister model? We need to keep an eye on this new platform, it's just TOO good.
 
I've got the 1000W Corsair 1000HX its running my 920@4GHz and two GTX 480(sli) and 4 hard drives at full load the system draws around 700W and the power supply is cool and quiet I think Corsair are one of the best manufactures in the world and they give you a 5 year warranty I only would consider this new model if I add another gtx480 to my setup but be sure when it comes to power supplies Corsair are number one.

Its a Corsair in house patented design so you wont see a sister model dude. Anyone could have built this technically.
