Like the title says, would my Cooler Master GM G750M be strong enough to run a fx 8350 at 4.2ghz and 2 280x in cf, these are the 280,s

XFX R9 280X 3gb, DDR5 Double Dissipation Black OC Edition

Going by the hardware with OC and how good the GM is i say no.
The Cooler Master GM is not horrible or anything but its not great either.

I say get an 850 watt Corsair RMx or EVGA SuperNova G2.
If you are going to BIOS volt mod both your video cards you are looking at a 1000 watt PSU.

1000W to be safe. 3 Power hungry components.

You should be okay, just don't run furmark & P95 at the same time.

I used to run an i7 920 @ 4.2GHz 1.45V and 2x HD 7950's @ 1150MHz 1.3V off an old Rosewill Xtreme 750W (Rev. 2) (which isn't as good as the CM unit) and I never had a problem.

An AMD FX CPU overclocked draws a hell of a lot more then a 920 does.
Same thing with the 280x they also draw a hell of a lot more then a 7950 ever did.

We are talking at least 125 watts more (if not more) for the 280x´s vs 7950´s, and at least 50 (If not 100) watts for a FX with OC vs a 920.

i7 920 is a power hog similar to AMD FX. 2600K is where Intel started focusing in power consumption. 280X and 7950 OCed use about same power.
