Recommended PSU for a triple crossfire RIG

[KingZeddy]

Hi,

I have a Asus M3A32-MVP Deluxe mobo which has quad crossfire support. I currently have three Radeon 3870HD cards on it and a AMDx2 6000 processor. One Sata drive and two DVD/Bluray Drives. I have been getting the odd reboot which I dont think is heat related, I wondered if it was due to the thermaltake toughpower 700w PSU being too weedy?

Can you recommend a good PSU - budget MAX £150, particularly as I am looking to pop a Phenon II 920 or 940 black edition into the mobo.

thanks
