Total Watts Help

[LRTom]

Evening

I'm about to go SLi and will need a new power supply. I will be running the following:

Asus A8N32-SLi
Opteron 144 @ 3.06Mhz
2 x 7800GT (Will be overclocked slightly)
Corsair 2GB DDR XMS3500LL

After much research I have decided to go for the FSP Epsilon. As most of my money is going on the second card and getting 2 AC Accelero X1's, I was wondering whether I could save money by getting the 600W model? Would this be enough for my setup? Or will it have to be the 700W model? Alternatively, any input on other makes? I've searched long and hard and found lots of info, but FSP seems to be coming out top, especially on price.

Thanks

Tom

Yeah, you should be ok with the 600W as they're good PSUs.

Have to agree, good PSU, but I would for the 700w job.

My 600W OCZ runs a very similar spec to yours with no issues. I'd say 600W would be fine but 700W would give some nice headroom.

Good calculator! Well I got 548W with a 25% surge so I think I'll go 600W.

So will I be buying pretty much the best PSU out there? So many contrasting views!
