850w good for 2 5970s?

post #1 of 10
Thread Starter 
So i should have a pair of 5970s in my future, Obviously 430w (current PSU) isn't going to cut it, so I am planning on buying this:

Mostly because it is smaller than most 850w units, and i have a small case.

Will 850w be enough or should i look higher?

Borderline. If you don't overclock them then ok.

Never get a drive bay PSU. All of the ones on the market are terrible. Except that FSP one... it was just mediocre.


Look for a quality 950-1000W power supply. Look in the recommended PSU faq at the top of this section.
post #5 of 10
I'd suggest at least a 1000w. eg. http://www.newegg.com/Product/Produc...034&Tpk=hx1050

I mean, you are running a quad gpu setup. And it's always good to have at least a little headroom so you can overclock

It'll run but you are cutting it close!

Guru3D recommends that you have 70amp on the 12v rail and that PSU looks to have a 72amps maximum of course quality PSU can always output above their maximum ratings.

are you talking about one of those "gpu dedicated" psu's? if so i'd advise against it.
many have stated that one high quality psu is better than 2 crappy ones(in general)
as for the 850W barrier, that's cutting it pretty close.

HX1000 is made entirely pointless by the HX1050:

Which is better in almost every way.


And of course there are even better 1kW units around.

Look at the silverstone strider gold 1000w. Its modular and relatively compact.
