Compact ATX Replacement for OEM Systems

The KHACHIMO PS-2151-08 is a 150 W ATX power supply designed to fit legacy OEM chassis that use proprietary pin-outs. It targets repair technicians and owners of specific branded desktops who need a direct swap without rewiring. Builders assembling custom ATX rigs should look elsewhere because the connector layout is not standard.

150 Watt Ceiling Limits High-Power Parts

The 150 W rating sets a hard ceiling on total system draw, so discrete graphics cards and high-core-count processors cannot be supported. Only low-profile GPUs or integrated graphics configurations will stay within the budget. The unit’s Modern Standby compatibility and 80 PLUS Gold efficiency help at idle, but they do not raise the peak output.

Eight-Pin Connector Dictates Compatibility

An 8-pin connector is the single specification that decides fitment; the unit ships with the exact pin arrangement required by the listed OEM motherboards. If the target board uses a different keying or pin count, the supply will not connect and no adapter is included. Verify the motherboard header before ordering.
