3.
Connect the 24-pin main power connector to your motherboard. If your motherboard uses a 20-pin
connector, detach the 4-pin attachment on the 24-pin connector.
Note: The detachable 4-pin section cannot be used in place of a 4-pin +12V connector.
4.
Connect the 8-pin or 4+4-pin connector for the CPU. If your motherboard has an 8-pin socket with a cover on
some of the openings, we recommend that you remove the cover and use the 8-pin connector.
Note: Please also refer to your motherboard user’s manual for any special instructions.
5.
Connect extra cables from the cable pack to the sockets on the power supply only if needed. If you are going
to plug the PCI-E cables into the PSU, they should go into the red sockets. If the red sockets are not being used
for PCI-E, then they can be used for any other type of cable supplied in the pack that accompanies the PSU.
6.
Connect the AC power cord to the power supply AC inlet. Be sure to use the heavy-duty cord supplied with
your CP-1000.
