Power Supply Units (PSUs)

Cables

Every cable a PSU provides is rated to provide a maximum amount of wattage.

Adapters

Here are a list of safe adapters to use. Providing lower wattage than what is expected can lead to a fire.

  • 2x Molex to 1x 4-pin CPU.

  • 2x SATA to 1x 6-pin GPU.

  • 1x Molex to 1x 6-pin GPU.

  • 1x Molex to 1x 8-pin GPU.

  • 1x 8-pin GPU to 1x 6-pin GPU.
