This is a power supply that was able to hold its own with the Enermax Galaxy Evo in terms of ripple suppression until it went and passed the output capabilities of said Enermax. This is a unit that put out some hundred and ten amperes of 12 volt current, all while regulating within 1% in the hot box. This is a unit that would not shut down in the hot box, even when confronted by temperatures well in excess of the specified operating temperature. When you get right down to it, this is quite simply the most awesome Enhance built unit I have ever seen, and in my view it is more than worthy of this here 10 I'm giving it.

I'd have a tough time deciding more so on the AX1200 (80+) or Enermax 1250 (85+) although I read up, despite the AX only being 80+ it is apparently more efficient then the Enermax, and it's FULLY modular, so I'd go with Corsair AX1200 all in all (may even buy one soon.)

If you need 1Kw, you're better off getting the HCP-1200 for $100 less. If you need +1200w, well... I wouldn't buy a 1200w PSU to handle +1200w, even though they can. If you need +1200w, you probably have a high-end 3way/4way SLI, or some power-hungry Quad-Fire. You can't pay $100 more for the ST1500? really?

There's no such thing as 85+. That's just a name Enermax puts in some of their models.
As far as certifications go, there's 80 Plus, 80 Plus Bronze, 80 Plus Silver, 80 Plus Gold, 80 Plus Platinum.
The Corsair AX1200 is 80 Plus Gold. The Enermax Revolution85+ 1250W is 80 Plus Silver.
In terms of efficiency, they're about even in actual testing, despite the AX1200 getting the higher rating.

He does not know how to do a review regardless of how many products he has played with. He knows very little about PSUs.

To add, efficency is also impacted on load. If you are running a 500w rig on a 1200w PSU, then you get better efficency getting a 800w PSU.

You do know that 2200w figure is taken from the wall?

You do know that there's still a lot more than 1200w taken from the PSU?

Judging from that response I'll assume you didn't know. Now you do.

Let's see video of the real input power consumption of GTX580 4way SLI of whole system.

It is around 1500~1600w from wall . Before unlocking OCP , it is around 1200~1300w .

The efficiency of HCP1200 is around 89% with such loading .

So output watt is around 1350~1400w
The 2200WAC output was with heavy clocks, volt mods, OCP disabled and such. 99% of people won't get anywhere near ~1700WDC with four GTX 580's.
