750W and 2 5970's

post #1 of 14
Thread Starter 
You think a 750 watt could power 2 5970's and overclock them amazingly? This is the psu I am thinking of getting if you have any better recommendations for a psu please post it!

You will definitely need more power. Just crank it up to a 850 or a 950 if you wish to be safe.

A Corsair HX850 will be more than enough to power x2 HD5970's.

850 or 950 my friend. 750 may be able to power them, but may crash when under full load, especially if oc'd.

750 Watts is alright if you don't OC your CPU & GPU and didn't do stress test (something like Furmark) on your GPU.
PSU recommendation?

Corsair HX850 should be fine.
Seasonic M12D 850 Watts is fine as well.
NZXT Hale90 850 might be the best choice if you also care about efficiency.

But even with 850 Watts, I don't recommend you to OC your CPU & GPU heavily.
Go for 950 or 1000 Watts if you want to OC it heavily.
NZXT Hale90 1000 Watts or Silverstone Strider Gold 1000 Watts should be okay if you aim for 1000 Watts.

5970's top out at just short 300w each even before over clocking couple in a decent cpu over clock and you'd already be at 750w before even ocing the cards or adding disk drives etc.

not sure how high an oced 5970's tdp is but i would guess you will want at least 850w probably even go as far as 1000w.
