These 24-pin connectors connect the mainboard to the ATX power
supply. Find the proper orientation and push down firmly to make
sure that the pins are aligned. The 8-pin connector provides a
dedicated power supply for the CPUs. For Wake on LAN support,
5-volt Stand-by lead (+5VSB) from ATX power supply must supply
at least 2A.
