Which PSU can power 4x HD 5970 , Core i7 990X , EVGA X58 Classified 4 way sli , 4GB x 6 G.skill ram.
I also plan on overclocking.
I have a HAF X chassis
Please help to find a psu that could easily fit inside the chassis

You should at least get a 1500w for the 4 5970s.
Are you quad firing them (which is two 5970s)?
Or Octo firing them(which is 4 5970s)?

1500W for 4 5970s (could work is the Silverstone ST1500 1500W)

I advise you to go higher if you are doing 4 5970s.

But if your doing 2 5970 then 800 should be enough or a 900w psu is better.

How many 6 to 8 pin pci e connector does the 5970 need?

You can have only 2 5970's. And basically any PSU could fit inside HAF-X.
I would recommend you these:

^+1 only 2x 5970's as they are dual gpu cards giving a total max of 4gpu's in crossfire.

I would love to no what your using this pc for and at what resolutions?

 

[julius 85]

And that motherboad might not support quad Crossfire.

EDIT: Nvm, it does.

Oh, and buying a 5970 isn't worth it, let alone 2 of them. You could get 3 GTX 580's, maybe even 2 GTX 590's for the price of 2 5970's

you gonna run bitcoin?

I hope you have some very loud speakers, as a friend of mine has a single 5970, and when he plays games it makes the same amount of noise as a Harrier Jump Jet performing a vertical take off.
