Avoid Mixing Power Supply Cables

WARNING

Don't mix PSU cables between PSU models!

Modular power supply units — PSU

Nowadays, power supply units are modular or semi-modular: all or some-of the power cables are removable for cleaner cable management. Additionally, all cables become black!

Example of a semi modular PSU and some removable cables

Power connectors pin layout

Power connectors are standardized on the device side (ATX mother board, PCIe Graphic Connector (PEG), SATA memory drives, "Molex", etc.).

Unfortunately, power connectors are NOT standardized on the power supply unit side!
