8. ATX power connectors (20-pin ATXPWR, 4-pin ATX12V)
These connectors are for the 20-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 fan cables to the fan connectors. Lack of
sufficient air flow within the system may damage the motherboard
components. These are not jumpers! DO NOT place jumper caps on
the fan connectors!
