Good deal for someone looking to build a PC. I just purchased a 750W HX750. If this would have come up a couple of days ago I would have definitely jumped on it.

Is this really enough for SLI/Crossfire? I would jump on this if it was the HX750.

wow
gold certified
modular
7 year warranty
...in!

Yes it is. You might be pushing it if you have some super OCd 7970s + a screaming OC on a 3770K, but that's about all that's going to give it any trouble. 680s in SLI would be fine and stock/moderate OCd 7970s would be fine.

ABSOLUTELY NOT. DON'T GIVE FALSE INFORMATION.

Can't comment on GTX 680

...but non-OC 7970 crossfire can easily reach ~500 watts alone. With a moderate OC and CPU OC, 7970 Crossfire can reach 800 watts system. There are bench of them reaching 900+ watts system with 1200/1600 OC.

I suppose that I should clarify that I consider a moderate overclock to be in the realm of 1000-1075Ghz like most of the Ghz edition cards are.

Most of these tests are measured at full stress bench load from the wall. A 650W gold unit can easily pull 750W from the wall. Typical gaming power consumption will also be a lot lower. Legit reviews [legitreviews.com] average over 6 games was only 373 for a single AMD reference GHZ edition card. Hardware Canucks [hardwarecanucks.com] had similar numbers for load scenarios.

If you're just gaming on stock or Ghz Edition cards, a 650W gold unit will handle it just fine. If you're going to be benching and pushing your clock speeds up to 1200/1600, you should probably be looking for a 750W unit.

If your PSU can handle 5/6 games, then can't output enough power on the 6th? How can you even justify the PSU. The point is that you can't run 7970 crossfire on 650 watts without choking your system.

And NO, power supply do not pull more than their rated capacity. Some PSU do pull more and are have their wattage under-marketed for whatever reason. Besides, it is bad idea to utilize a PSU near 100% capacity.

Finally, you link me to reviews clearing showing that a single 7970 system bulls 412/399/391 watts respectively and you are stilling me that you can run 7970 crossfire on 650 watts?

No game is going to vary that much. The only time you'd be pushing it is if you're doing stress tests for an overclock.

Yes they do. Why do you think places like Hardwaresecrets run overload tests?

Yes. Those are all total system draw measured at the wall.

Sigh.. I'm so tempted to pick this up to replace my TX650 V2 because I want a modular PSU to clear out some space in the bottom of my case...

Get better case. Hide cables...
