I have heard of problems with dual rail PSU's, but don't really know anything about it, but sometimes they work.

want to plug two power greedy cards inside. You need a lot of quality single rail power, not just any power.
I remember there being a link in there for a 30a single rail'd PSU, but can't find it.

No, go with Dual 12v rails of at least 28 amps I'd say, 26 at a minimum. That's with at least 600-650watts. If you havn't purchased your system yet, I'd suggest not getting SLI at all.

well... i already have my system, i'm just soon switching over to sli and i need a good psu for it. I already have a 7900gt, and i'm getting my 2nd soon enough

and there's nothing wrong with sli, dual 7900's run alot better than any single card solution for a nice price... better than buying a 7800gtx 512mb...

Nah, I would of saved that money of needing to buy the new PSU and video card that will grant prolly 50% of a performance boost if your lucky.

well, i still need a new psu no doubt, this one i have is on the verge of dying any minute.... its terrible.. 19a i think it was... ya, so i do still need a psu.... and a graphics card.. i dunno, maybe a new processor.. or hdd... i dunno, most likely another 7900.. hard to change this mind, i just want to take the title from my neighborhood of having the best computer

and not only that.. i'm pretty sure a single 7900gt won't handle ut2007 and other games later on this year at full quality... i want nothing less than maxed out!

My Antec came with with dual 6 pin rail connectors for SLi (smartpower 2.0 500 wt and I only paid $73.95 retail at a local store in CA) and are the 6pin removable type connecotrs to the PSU. Very quiet PSU. Second fan only comes on under high power usage.
