  • Enables use of existing PSU with newer 8-pin motherboard sockets
  • Features ATX 12V 4-pin female and EPS 12V 8-pin male connectors
  • Delivers 12 V power through adapted connector configuration
  • Simple adapter cable solves CPU power connector mismatch

4-Pin to 8-Pin EPS 12V Adapter

This adapter cable converts a standard ATX 4-pin 12V female connector into an EPS 8-pin 12V male connector. It is intended for builders who have an existing power supply with only the older 4-pin CPU power lead but need to connect a motherboard that requires an 8-pin socket.

Power delivery limited to 4-pin source

The adapter cannot increase the current capability of the original 4-pin rail. The motherboard will still draw power through the same 12 volt lines present on the 4-pin connector, so total available power remains constrained by that source and the supply's rating.

Check motherboard and PSU compatibility

Verify that the motherboard will boot and run stably with only half the 8-pin socket populated via this adapter. Some boards require the full 8-pin connection for high-load operation. Also confirm the power supply's 4-pin connector is a standard ATX 12V type and not a proprietary variant.

Questions about this item

Should I use this adapter if my power supply only has a 4-pin CPU connector and my motherboard needs an 8-pin EPS 12V socket?

Yes, this cable converts the ATX 12V 4-pin female plug from your supply into an EPS 12V 8-pin male connector that fits the motherboard socket.

Will the 4-pin to 8-pin conversion deliver the full 12 V power my CPU needs?

The adapter passes the 12 V lines through, but the supply still provides only the current its 4-pin connector was designed for, so high-draw CPUs may be limited.

What connectors are on each end of this ATX to EPS adapter cable?

One end has an ATX 12V 4-pin female connector for the power supply, the other end has an EPS 12V 8-pin male connector for the motherboard.
