250W ATX power supply for compact builds

This KHACHIMO unit delivers 250 watts through a standard ATX form factor. It suits small-form-factor PCs, office workstations or home-theatre systems that draw modest power and need reliable, efficient delivery. The Modern Standby capability makes it a good match for systems that spend long periods in low-power sleep states.

Fits standard ATX bays and frees cable space

The supply mounts in any ATX-compatible chassis and uses a resonant LLC topology with DC-to-DC conversion to keep output clean across varying loads. Its 80 PLUS Gold rating reduces waste heat, so case airflow requirements stay low. A single 6-pin connector is provided for auxiliary power needs.

Zero RPM fan mode cuts noise at idle

At low and medium loads the cooling fan stops completely, giving near-silent operation during typical desktop or media tasks. The same topology also suppresses coil whine, so the system stays quiet even when the fan spins up under heavier demand. Modern Standby support enables faster wake times without extra configuration.

Perguntas sobre este artigo

At what load does the 250 W limit become the first bottleneck during sustained use?

The 250 W rating is the maximum continuous output; sustained demand above that level will trigger protection or shutdown.

How does the Zero RPM fan mode affect noise and temperature during all-day operation?

At low and medium loads the fan stops completely for silent running; under heavier loads it spins up to maintain safe temperatures.

Which connectors must the motherboard and graphics card already provide for this unit to work?

It requires a standard 24-pin ATX main connector, a 4/8-pin CPU power connector and a 6-pin PCIe connector for the graphics card.
