KHACHIMO 145W ATX Power Supply 80 PLUS Gold FSP145-51CI FSP250-51

KHACHIMO 145W ATX Gold PSU

This 145W ATX power supply carries 80 PLUS Gold certification for high-efficiency operation. It targets small-form-factor or low-power builds that demand clean delivery and quiet running. Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion reduces coil whine and supports deeper sleep states.

Check ATX fit and wattage headroom

Verify that your chassis accepts a standard ATX power supply and that 145W covers the combined peak draw of every installed component. Confirm the unit's fixed cable set matches the motherboard, CPU and peripheral connectors your build requires. Ensure the cooling airflow path in your case can accommodate the fan even when Zero RPM mode keeps it stationary at low loads.

Sustained load behaviour and thermal profile

Under continuous load the 80 PLUS Gold rating ensures efficient conversion, limiting waste heat and keeping internal temperatures lower than less-certified units. The fan remains off during light and medium workloads thanks to Zero RPM mode, activating only when thermal thresholds demand active cooling. Resonant LLC with DC-to-DC conversion maintains stable voltage regulation across extended sessions, minimising ripple and coil noise during prolonged operation.
