Replacing power supply

Gateway Desktops performance 500 deluxe
February 27, 2010 at 13:57:48
Specs: WINDOWS XP
WHEN REPLACING FAILED POWER SUPPLY WITH
HIGHER WATTAGE POWER SUPPLY, I LOST TRACK OF
CONNECTIONS. ANYONE HAVE
ANY HELP FOR WHICH CONNECTOR GOES
WHERE? OR, MORE TO THE POINT, WHICH
CONNECTIONS ARE NEEDED. I LOST MY LIST OF
DISCONNECTIONS. I HAVE TOO MANY
CONNECTORS BUT I AM NOT SURE WHICH
ARE NEEDED TO POWER UP AND RUN THE BASIC
COMPUTER. I HAVE A GATEWAY MFATXPNT, MODEL NO. 500S PO4. IT IS RUNNING ONE HARD DRIVE. I AM TRYING TO INSTALLING A 450 WATT ATX12v2.2 POWER SUPPLY. I'M A 77 YEAR OLD NEWBIE.

It's pretty tough to get it wrong. Click on the links to see pics of the connectors.

The main power to the motherboard is supplied by either a ATX 20 pin main power cable or ATX 24 pin main power cable & there should also be a square 4 pin ATX +12 volt power cable that connects to the board in the vicinity of the processor.

Hard drives & optical drives are powered by either a 4 pin peripheral power cable or an SATA power cable.

The floppy drive (if you have one) is powered by a floppy drive power cable.

If you have a video card, it *may* require an aux power connector. Sometimes it's a 4-pin peripheral or floppy drive connector, but it could be a 6 pin PCI Express power cable.

Considering the varying sizes & shapes of the plugs, it's virtually impossible to do it wrong. There are almost always several extra plugs available when you're done, that's normal...they're for future upgrades.

Thanks for the great answer. I found I had connected the wrong 4 pin connector. Fortunately, when I connected the right one, everything seems to be working ok.
Once again, Thank YOU for taking the time to answer.
