300w and 10a on one 12v line. this thing powers 1 6800gt, 1 overclocked amd 64 3200 2400mhz, 1 cd-rom 52x max LG, and thats it, all pci slots are empty. My system only posts and turns on normally when i set the ddr ram voltage to 2.6 ( i think 2.5 is default). I am 2 x 256 dual channel ddr 400 infineon ram. Is it my power supply not giving enough power to the infineon rams? I have to like put in my old ddr 2100 ram then go to bios and switch the ddr ram voltage to 2.6v, then put in the new ddr 400 infineon rams. Why cant the infineon ram post up my computer with the default bios settings? My monitor just stays off at 2.5v.
