What to know before buying

The 8-pin male connector is stated to be for a motherboard CPU socket only, not an 8-pin graphics-card socket. Confirm the connector type and PSU-to-motherboard compatibility before use.

Listing details to confirm

Listing details are inconsistent about connector description: the title says 4-pin female to 8-pin male, while a feature says 4-pin male to 8-pin male. The description also calls the 4-pin connector a Molex that is actually a 3-pin specification, despite naming it a 4-pin ATX adapter. Confirm the exact connector and pin arrangement before buying.

Who is it for?

A good fit for

PC builders whose power supply has a compatible 4-pin CPU power lead and whose motherboard has an 8-pin CPU power socket.
Buyers who need several short internal power-adapter cables.

Less suited to

Anyone needing a graphics-card power adapter or an 8-pin GPU connector.
Buyers whose PSU or motherboard connector does not match the cable's actual pin arrangement.
