Well going with a Seasonic isn't exactly cheaping out, I just thought that I'd have more breathing room, like 50w.

The PSU is 620W.
The 2 graphic cards consume 600W.
The CPU consumes 120W (OCd).
That's 720W already. +HDDs, +Fans, +RAM, +everything else - full load is hitting the 800W mark.
Realistic load (heavy gaming) would put it around 700.

How does a 620W PSU "handle" that?

The 600w on anand bench is for the whole system.

I'm guessing that the X-750 can handle it then. Just one question; Is it modular?

It will work.

You only need a good 400W PSU to run a 130W CPU and a single 6970 with some headroom.

All of Seasonic X series PSU are modular, might also want to take a look at Corsair AX 750 as it's the same unit (technically it's same as X-760) but with better cabling, longer warranty and usually cheaper.

Very true. SeaSonic isn't a cheap brand, they're high quality. And people often grossly miscalculate what they need. Like, Stefy, who has a 700 W for a system that draws 500 W at most and is planning to upgrade to a 1000 W (the only valid reasons for a 1000W being 3-way CF or 3-way SLI or a dual socket mobo, but maybe he's actually getting that).

Also, a single HD 6950 draws 160 W and 2 would probably draw ~300 W. Overclocked, you might get a draw of 350 W. Then an OC'd i7 and you're pulling 180 W extra. Then add 50 W for mobo, HDD's and fans. 350 + 180 + 50 = 580 W. And that's an absolute maximum draw which your system would rarely see.

Hey guys off topic but seems like the crowd that would know.

I have a similar question about my setup in my sig adding a 6970.

Whats the best wattage reader out there? Like to read what I'm pulling from the wall. How much do they cost?
