(Apologies if this is in the wrong section)

How ya doin' folks,

I've recently got hold of a second 5770 and was wondering if my current PSU will hold up with Crossfire.

At the moment I'm using:

But I also have an Atrix EXTREME Power Supply 720W ATX PSU Dual Rail 135mm Dual Bearing Silent Fan laying around.

My current rig specs are:
- CPU: AMD Bulldozer FX-7 Eight Core 8320 3.50GHz with 4.0GHz Turbo enabled
- Motherboard: Asrock 970 Extreme3 R2.0 (Socket AM3+) DDR3 Motherboard
- RAM: 8GB 1600MHz Dual Channel DDR3 RAM
- Sapphire HD 5770

Cheers guys,

JD

Hi. The OCZ has 25a on the +12v rails and might do it. The Atria although 720w, only has 20a on the +12v rails. Not sure of what that card requires, but you are talking two in XFire.
