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.
3.
Connect the 8-pin or 4-pin ATX12V connector for the CPU to the appropriate connector
on your motherboard. 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.
4.
Connect the PCI-E connector(s) to your graphics card(s), if applicable.
5.
Connect all Molex/SATA connector(s) to your hard drives, optical drives
(CD/DVD/BluRay™) and other accessories. Please note that some devices will use either
the older 4-pin Molex connectors, while others will use the newer 5-pin SATA connector.
4-pin Molex connectors have two black wires, a yellow, and a red. The SATA connector
has an additional orange power wire.
