[Ronnie]

im planning on getting 2x2900pros, a water loop, and then my current rig
my question is will my psu be enough to handle it?
or should i sell it and get something new?

thanks in advanced

should have no problems

cool, that will save me some dough for my WC setup

as long as theres enough amps on the rail it will be fine

I haven't used Hiper before. But aslong as it's a good solid 580W with enough amps, you'll be more then fine.

If I were you I'd change it. Hiper PSUs are not known for their quality and the 580w only has 2 rails rated at 20 and 18 amps.

The R600 isn't the most efficient card and 2 of them in crossfire will put quite a heavy load on the system.

Something like this would be ideal
Newegg.com - CORSAIR CMPSU-520HX ATX12V v2.2 and EPS12V 2.91 520W Power Supply 100 - 240 V UL, CUL, CE, CB, FCC Class B, TUV, CCC, C-tick - Retail

Yes you should. At the least a Corsair 620

Some have been running forever without problems but they do have a reputation of blowing up. There's a thread on another forum dedicated to blowing up hiper 580w psus and I can tell you there are dozens and dozens of very unhappy people in there.
