[rico3]

since the release of ATI new graphics card the Radeon HD 2900 512MB ,ive been thinking of getting a new computer setup and trying this card out.... here on oc web page they are selling a crossfire pc setup..http://www.overclockers.co.uk/showproduct.php?prodid=FS-047-OK&groupid=43&catid=781&subcat= what is the power supply needed for crossfire set up? as ive seen other manufacture selling crossfire setup with 520watt power supply...surely that isnt enough power for dual ati radeon HD 2900 512MB in CROSSFIRE...

The PSU in that system is this one:

520 is pushing it for 2 HD2900XT i must admit.

If you do get a system, personally i would just get a GTX.

yeah got it wrong its a Hiper Type-M SLI/Crossfire Ready 580 Watt Power Supply... but i still dont think its powerful enought...

520W is enough for a single 2900XT, it doesn't use much more power than a GTX.
