TwoCables why didn't you mention this? Power consumption, at least with my 770's, is about 620W.
OP. If you wanna run dual GPU's, your gunna have to get a different PSU.
Do you mean 620W from the wall, or from the PSU? If that's from the wall and if your PSU is 90% efficient while pulling 620W from the wall, then that means your computer is pulling 558W from the PSU. However, I'd say that it's more likely that you're pulling 620W from the PSU because you have an overclocked 3930K which can pull 325W when heavily overclocked. Generalkayoss only has the 4670K.
Also, there was nothing to mention. Look at this:
With two GTX 760's under full load in their system, their PSU pulled 449W from the wall outlet. Their CPU was idling, so I will add about 125W for his 4670K since that H60 won't allow him to overclock very far. Adding this to the 449W makes the PSU pulling 574W from the wall outlet. So, if his PSU were 85% efficient while pulling 574W from the wall, then that would mean that his computer is pulling 488W from his PSU. This is an unrealistically high power consumption though. A more realistic power consumption will be seen while gaming, and that will never exceed roughly 450-475W. That's a walk in the park for the CX750M. Even 550W or 600W would be fine. It's not THAT bad of a PSU. Yeah, I would never recommend it, but I'm not completely against it either.
So yeah, he is absolutely fine.
