power connectors from the power supply to the motherboard, do the following:
1. Plug the 24-pin or 20-pin main ATX keyed power supply connector into the mother-
board power socket. You can plug a 20-pin connector into a 24-pin socket (and vice
versa) by connecting them in an offset fashion, or you can use cable adapters to mate
them up. Most ATX systems also use a 4-pin or 8-pin ATX12V connector. These are
also keyed and plug in only one way (see Figure 19.25 ) .
2. Connect a power lead from the power supply to the CPU fan if the motherboard does
not have a CPU fan power connector.
