Hey all,

I have a 650W Corsair GOLD PSU and was wondering if any has tried a 650W? I don't want to have to upgrade if i don't have to. I read these cards are very efficient.

It will be enough. The 970 has a TDP of 145w. Double that=> ~300w + other components (~150w) = 450w. So it should suffice.

A good 750w is a better choice , 650 is cutting it too close.

I agree, especially when you have superclocked cards with high wattage coolers. Or you have a highly overclocked cpu also.

650 should be fine, it does seems a little edge cutting. but it will be fine if you are not overclocking hard.

if you want to be safe about your new investment, get a 750w, evga supernova 750 is on sale.
