200W ATX Gold power supply

This KHACHIMO unit delivers 200 watts of ATX power with 80 PLUS Gold certified efficiency. It supports Modern Standby for rapid wake-from-sleep performance. The resonant LLC topology with DC-to-DC conversion provides clean, stable voltage rails. A zero RPM fan mode stops the fan entirely at low and medium loads for silent operation.

Suits compact Gold-efficiency builds.

This supply fits builders who need Gold-rated efficiency and silent running in a 200 watt ATX form factor. It works well for Modern Standby desktops and low-power workstations. Systems with discrete graphics cards or multiple drives requiring more power should look at higher-capacity units. Buyers needing 300 watts or more cannot use this model.

200 watt maximum output decides fit

The single specification that determines compatibility is the 200 watt rated output. Your total system draw under full load must stay below this figure. Check the combined power draw of your CPU, GPU, drives and peripherals before selecting this unit. If the build requires more headroom, a larger supply is necessary.

Questions about this item

What ATX form-factor clearance does the 200 W unit need inside the case?

It fits a standard ATX power-supply bay; allow space for the rear power-cord socket and the modular cable plugs that extend from the front face.

Which mounting screws secure the supply to the chassis?

Four standard ATX case screws through the rear flange hold the unit; tighten them in a cross pattern so the housing seats evenly before connecting cables.

When should the internal cooling fan be cleaned to keep zero-RPM mode working?

Remove dust from the fan grille whenever case airflow noticeably drops; a blocked grille stops the fan from spinning down at low load.
