KHACHIMO HF55W-DE-L 55W ATX power supply

55W ATX power supply with Gold efficiency

The KHACHIMO HF55W-DE-L is a 55W ATX power supply built for systems that prioritise low power draw and quiet operation. It carries 80 PLUS Gold certification and uses a resonant LLC topology with DC-to-DC conversion to deliver clean, consistent power. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. A zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent running.

Suited to compact or low-power builds needing Gold

This unit suits builders assembling compact or low-power systems that benefit from Gold-rated efficiency and silent low-load operation. Modern Standby support makes it a good match for PCs that spend long periods in sleep states. Buyers who want more storage or multiple high-draw graphics cards should look elsewhere, as the 55W limit cannot sustain heavy multi-component configurations.

Sustained load behaviour with fan-off capability

Under sustained load the resonant LLC topology with DC-to-DC conversion maintains clean power delivery and reduces coil whine. The zero RPM fan mode keeps the fan stopped through low and medium loads, so noise stays minimal until higher thermal demands require active cooling. Gold-rated efficiency helps limit waste heat during continuous operation, supporting cooler internal temperatures over long sessions.
