750w for 5970?

[gangstativ]

Hi. I've just built a new rig, consisting of the following hardware:

Asus P7P55D-E pro
i7 860
8gb G-skill eco
Chieftec Super Series 750w
3 hdds
1 optical drive

Will the psu be sufficient for a 5970? And oc, too.

I would be a little worried about this particular psu. I've never seen the brand before looking it up and it's rated at 750watts maximum not continuous. So you could probably get by with it, but i would suggest getting a psu rated at continuous even if it's a lower rating, a 650 continuous, IMO would be a better buy

The Chieftec power supplies are very good. Very little ripple, within 1%

750W would definitely be enough. Enough for an additional 5870 or 5850.

Never heard of Chieftec? Wow... :O

Well, the psu was made by the same company that makes Corsair and Enermax, afaik, the base is the same.

You'll be fine.

Great. And there seems to be space for some OC, too.

Thank you.
