gtx 770 = 230W max tdp
2 gtx 770 = 460W max tdp

so yes depending of which kind of cpu you have

tdp is thermal design point thats heat not power a single gtx 770 uses about 300w there or there abouts on load, i have an i5 4670k overclocked to 4.4ghz its in my sig

Thermal Design Power (TDP) represents the near maximum power a product can draw for a thermally significant period while running commercially available software.

i5-4670 = 84W
so 460W + 84W = 544W max tdp

If you had the same one from review, you are good to go even it is old model, becuase from the review it can output up to almost 1000W, WOW.

Thanks for the article links wow 1000w that seems an awesome jump in power i was keen to know was the actual psu good that i was not putting too much pressure on it with a second gtx 770 im thinking i might chance it now

TDP (power point profile) its the thermal is the important word its technically the max amount of power the cooling system needs to dissapate. Its not the maximum amount of power a component can draw. An i5 4670k is 84w stock

Hi, our HCG-750 is strong enough.

And TDP is the average thermal heat dissipation of a processor under a certain scenario, which Intel, AMD and Nvidia define very flexibly for their products.

It is by far not the total amount of power drawn :-)
