Ok I've basicly narrowed the selection of power supplies down to 2 brands. Thermal Take and PC Power and Cooling. http://www.pcpowercooling.com/products/viewproduct.php?show=T51SLI http://www.thermaltakeusa.com/2005/purepower/w0083/w0083.htm http://www.thermaltakeusa.com/2005/purepower/w00101102/w00101102.htm For now I'm running an AMD 64x2 4400+ Toledo core, an ATI X1900XT 512mb video card, Soundblaster ZS platinum pro, 10k hard drive, DVDrom and a DVD writer, probably will put a floppy in eventually. The case is a Thermal Take Xaser Armor with 4 case fans. I may want to add an extra fan or two in the future. The motherboard is an ASUS A8N SLI Premium(I couldnt find a crossfire I liked) Any suggestions on which of the power supplies? Edited: I forgot to add which heat sink would be good for the AMD chip?
