Im running on this PSU right now

Newegg.com - ENERMAX Liberty ELT400AWT 400W ATX12V SLI Ready CrossFire Ready Modular Active PFC Power Supply - Power Supplies

I've got an e6750 3 gigs of ram and a 750g seagate.

im tired of my 7900gs and i wanna upgrade.

i've read stuff here and there about being able to run the 4830 on a 400w. Any thoughts?

i'd also like to ad that i'm probably gonna throw in another 750g and a 80g raptor in there as well as a few more gigs of ram in the near future.

It will be fine 4830 is around 110W you could probably step upto a 4850
E6750 = 65W
mobo+ ram overhead = 25W
hdd = 10W each
optical = 5w

total = 225W

I would go for the 4830 and do some overclocking on both CPU and GPU. Let the overclocking fest begin!

Dual 20A rails should be fine.
