KHACHIMO 250W ATX Power Supply NPS-250FB B P3117

250W ATX Power Supply for Desktop Systems

This 250W ATX unit delivers reliable power for standard desktop builds and compatible OEM chassis such as the 600SC, 2400, 3000, 4100, 4300, 4400, 4550, 4600, 8250, and 8300 series. It carries 80 PLUS Gold certification for high efficiency and lower running costs. Modern Standby support enables extremely fast wake-from-sleep times and improved low-load efficiency. The Resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine.

Standard ATX Fit with Zero RPM Fan Mode

Installation follows the standard ATX form factor, so it fits typical mounting points and uses familiar connector layouts. The Zero RPM fan mode keeps the cooling fan completely off at low and medium loads for near-silent operation, then spins up only when thermal demand rises. Ensure the case provides adequate airflow for the fan when it becomes active and that cable routing does not obstruct the exhaust path. Verify that your motherboard and components match the connectors supplied with this specific unit.

250W Limit Defines Component Choice

The 250W rated output sets a firm ceiling on the total system power draw, so high-end discrete graphics cards and heavily overclocked processors are not supported. Builds that require more than 250W combined load will exceed this supply's capacity and risk instability or shutdown. The 80 PLUS Gold rating helps minimise waste heat within that envelope, but it does not increase the maximum deliverable power. Plan the complete system power budget before committing to this unit.
