Compatible Desktop Power Supply

The KHACHIMO 450W ATX unit fits the listed Dell and Lenovo small-form-factor desktops including 280G2, 400G4, m710e, 720e, 510S and M420 models. It replaces multiple original part numbers such as PA-1450-1, PCH018, PA-1181-7, PCK027 and PA-1261-7. Buyers needing a non-standard proprietary pin-out should verify their chassis wiring before ordering.

Build Quality and Connectors

An 80 PLUS Gold rating means higher efficiency at typical loads, reducing waste heat and allowing the fan to stay off longer. Resonant LLC topology with DC-to-DC conversion delivers stable voltages and limits coil whine. The included 6-pin connector matches the motherboard power header on the supported platforms.

Modern Standby and Accessories

Modern Standby compatibility enables extremely fast wake-from-sleep and better low-load efficiency for always-connected workflows. Zero RPM fan mode keeps the system near-silent during light office tasks or media playback. No extra cables or software utilities are bundled with the unit.
