Anyone know if R2E will work with this PSU

That PSU is fine, but the other components that you'll install in your system determine if it's adequate or not.

A single GTX280 FTW edition, with an i7 core 920 with 6gb of Corsair Dominator 1600 mhz... still good enough GhislainG? Thanks bro.. let me know when ya get a chance

According to Antec (http://www.antec.outervision.com/), you should be fine. To your list, I overclocked the CPU, added 2 hard disks, a DVD-RW, a few fans and USB devices. You would then require a 510W PSU.

Thanks a lot
