Dual Power Supplies

[Maximus22]

I was just wondering if there was a way to hook up two power supplies together in one computer. I have a 250 watt power supply and a 300 watt power supply and I want to get ready for dual athlons with scsi everything. I just want to know a way to hook them up so it will be like i have a 550 watt ps.

anyone???

no because your motherboard has only 1 plug for 1 power supply !

I read somewhere that you can split certain wires on the ps and join them as if you had one ps. If any one can tell me where i can find this tutorial.

Sure you can have two P.S.'s start at once so you can use the extra plugs to hook up devices (not the M.B. connector)

If you try to splice wires together, you'll get in big trouble by confusing the regulator of each supply and possibly cause oscillation and make the transistors short.

Keep each power supply separate except for their grounds (black wires - tie them to a common ground). IOW, use one supply for your motherboard, another for your peripherals. Plug both supplies into a power strip, and use the power strip's switch instead of the computer's. The reason for this is because ATX supplies need a zero voltage on ATX connector pin 14 (green wire, opposite red wire and between two black wires - can get zero volts by shorting green to black).
