I need a new one, but I was actually googling an alternative to a whole new and expensive power supply. I want to run two power supplies at once for one system, and I just had a couple of questions. 1. According to some places, I can just put both PS-ON wires together and two grounds and call it good, would that work with two different power supplies? 2. Would anything detrimental come about from powering a graphics card from one power supply and everything else from the other? 3. Is wiring grounds together (like in #1) a bad idea? 4. Would slightly-different voltages between the two power supplies cause something to go wrong? (i.e. let's say that graphics card is taking in 12.025V and mobo is taking in 11.995, will there be problems?) Here's rig: athlon x2 6000+, OC'd to 3.2GHz 2GB ddr-800 3 Harddrives 1 DVD drive Nvidia 8800GTS Overclocked (slightly) Biostar Nforce4-Ultra Hauppage TV tuner My main power supply is 450Watt, not the advertised 575W, the latter is the max rating, and the first is sustained. It was less than $40, so it's crappy as hell. The second power supply is a 350Watt Cooler Master, and it's pretty old. My main power supply puts out 25A on +12Volt, and the second one puts out 16A on the +12Volt rail.
