Hello everyone,
I'm planing a new PC build but i'm not sure what kind of psu i need.

The components i'm going to use are:
Cpu: Intel core i7 2600k
Ram: 8gb ripjaw 2133 2x4gb
Gpu: 2 AMD radeon 7970 crossfire or 2 AMD r9 280x crossfire (depends on the deals that i may find)

I don't think i'm gonna need to overclock but it would be nice if i could :)

I have found a deal on a corsair cx 750w psu for 45 dollars, should i accept that deal?

The CX is not a good PSU and the the load of 2 of those cards would most likely make it fail faster. 750w would be the bare minimum, I recommend a 850w unit especially where you may OC later. The EVGA(B2, G2 or P2), XFX, Seasonic, Super Flower, or Antec are good units. And any reason why you are getting the 2600k over the newer generation? For what 2 280x cost(atleast in the US) you could almost get a single GTX 980 which is almost as fast but uses alot less power. Getting single faster card is usually a better option than 2 mid range units.

Thanks for the fast reply!
I can buy 2 r9 280x's for around 280,- dollars and 2 7970's for even less.
I am buying a 2600k because i can get a whole system for 340 dollars with a 2600k, but i think i'm going to buy al the parts myself and get better bang for the buck.

If i find the right deals (im gonna find them!) my system will cost around 625 bucks with an i7 and 280x or 7970 corssfire :)
