24-Pin to 12-Pin ATX PSU Power Adapter Cable | Motherboard Converter

The 24-Pin to 12-Pin ATX PSU Power Adapter Cable provides a practical solution for connecting a standard 24-pin ATX power supply to compatible desktop motherboards that use a proprietary 12-pin main power connector. It is especially useful when replacing an original proprietary PSU with a standard ATX power supply in compatible Lenovo and IBM desktop systems.

This adapter allows you to use a compatible higher-wattage standard ATX PSU without modifying the motherboard's original power connector. The cable uses a compact design with 18AWG wiring and is commonly supplied at approximately 15cm in length, making it suitable for internal desktop PC installations where the power supply and motherboard are positioned relatively close together.

The adapter is commonly listed for systems including Lenovo ThinkCentre M92P, M93P, H530 and selected Q77/B75/A75/Q75 platforms, as well as ThinkServer TS140 and TS440. Some versions are also sold for Acer Q87/Q87H3-AM motherboards, so pinout compatibility must be checked before installation rather than relying only on the physical 12-pin connector.
