Internal power cables

Inside a PC, the power supply connects to drives, fans and graphics cards with a range of connectors. SATA power cables feed modern hard drives, SSDs and optical drives, while older drives and many fans use the 4 pin Molex connector. Splitters and adapters let you power an extra drive or convert between the two types.

ATX extension cables add length to the motherboard power connector in larger cases, and PCI Express cables power graphics cards. Always check the connector and the power supply capacity before adding devices.
