PSU good enough for xfire???

[RavenUK]

I'm considering buying another 2900 to do some crossfire to get max performance for when crysis hits the shelves, thing is I'm not sure if my PSU will handle it, if i have to go to the expense of a new PSU then i guess i will, it just means the dog will go without his winalot for the next few months appreciate any thoughts on the matter.

My current PSU specs....

Pretty sure it would be fine, a little close maybe but IIRC those Tagans are good PSUs.

Ill give it a blast with my current PSU then, if it blows I'm holding you responsible...

If I'm right you have 576w odd on the 12v rails, that should do the trick, maybe pushing it though, not too sure.

Check some 2900 reviews, they will have the power consumption stats and such.

Xfire 2900s and a C2D OCed with 48A@12v? Easily.
