I'm currently checking out a shop, which is nice, but has limited choice. From the following powersupplies, which PSU would be best for a pretty heavy gaming rig with SLI? (I'll start with 1 card first, then add another one in SLI mode within 1 or 2 years) AKASA Powersupply ATX/EPS 12V 550W 80mm Denki Fan, SATA, 24/20pin AKASA Powersupply ATX/EPS 12V 650W 80mm Denki Fan, SATA, 24/20pin Antec Phantom 350W Fanless Stealth PSU Fortron/Source PSU ATX 550W Bulk, 120mm, SATA, 24pin, EPS12V NorthQ 4001EXT, Silent ATX 400W, 140mm Fan, 12-17dBA, 2xSATA, PCI-E, 20/24pin NorthQ 4775-400, ATX 400W Silent, 140mm Fan, 12-17dBA, 4xSATA, PCI-E, 20/24pin NorthQ Powersupply 4100 ATX 520W Silent, 120mm Fan, 12-17dBA, SLI, 20/24pin OCZ Technology Powersupply ATX 450W 120mm Fan, SATA, 20/24pin Tagan Easycon 430W, Modular Cables, 120m Fan, 4xSATA, ATX/EPS, SLI, 20/24pin Tagan i-Xeye 420W, Dual Fan, Blue Light, 2xSATA, ATX/EPS, PCI-E, 20/24pin Tagan 2force 480W, Dual Fan, 4xSATA, ATX/EPS, SLI, 20/24pin
The only two in that list that would likely be able to cope would be the Fortron Source 550W or the Tagan 480W. I'm never heard of NorthQ before, so I'd avoid them simply because of the unknown. I've heard of Akasa, but only in regards to heatsinks, not power supplies. OCZ I know is good, but the 450W is likely to be lacking. Tagan is also a good company, but the 480W is the only one that I'd look at...and that would be a minimum. If that shop could get ahold of the OCZ 520W, that'd be a good choice if they could get it in.
