2. ATX power connectors (24-pin EATXPWR, 4-pin ATX12V)
These connectors are for the 24-pin and 4-pin power plugs from the
power supply unit. The plugs from the power supply unit are designed
to fit these connectors in only one orientation. Find the proper
orientation and push down firmly until the connectors completely fit.
Do not forget to connect the 4-pin ATX12V power plug to the ATX12V
connector on the motherboard; otherwise, the system will not boot up.
