How To Replace Your Power Supply

Removing The Power Plugs

Remove all power connectors that are installed on different devices inside your computer. In our case our computer had a CD burner, a hard disk drive and a floppy disk drive, so we had to remove the power connector from these three devices, plus the motherboard. Depending on your configuration you will need to remove more cables.

As for the motherboard, usually two connectors are used: a main connector with 20 or 24 pins and an auxiliary 4-pin connector, called ATX12V. Some low-end motherboards don’t have this ATX12V connector. You need to look for it carefully as usually it isn’t located near the main power connector – even though on our motherboard they were located side-by-side, this setup isn’t the usual one.

Remove the motherboard power connectors is a two-step procedure, first press the latch located on the middle of the connector and then pull the connector up. In Figure 9 we illustrate the removal of the main motherboard connector and in Figure 10 the removal of the ATX12V auxiliary connector.
