ATi HD2900XT 1GB, 600Watt Good enough?

[TheBOSS]

Hi all, I just got a Sapphire HD2900XT 1GB DDR4, which is supposed to run at core clock:750ish Mhz, and memory clock:2000Mhz.

Mine is currently running in safe mode, at core:501Mhz and memory:1014Mhz.
I currently have an AOpen 540Watt, in a rather lovely gold colour, which clearly isn't gonna cut it anymore.

I've been trying to find what the required PSU is. The ATi site doesn't have the 1GB DDR4 card, only the 512Mb DDR3 card. They say at least a 550Watt with 2x3pin PCIe connectors. I found another site, for the Diamond HD2900XT 1GB DDR4, and they reccomend a 750Watt PSU, however I think their card is slightly OCed, Memory is at about 2200Mhz.

I can't even open 3Dmark05 or 06.

Please someone help!!!!!!!!!!

Will the iSonic Megapower 600Watt be good enough?

550w PSU, with sufficient Amperage on the +12v Line, should be enough for any XT, that 750w suggestion was bunk. As above, make sure the amperage is ample, this is just as important as wattage, the XT needs +12v@32a.

600W is fine. Unless it's a case PSU or eBay 600W.

Rosewill Stallion 600W is good...
