400 W ATX power unit

This KHACHIMO PWS-0042-24 unit delivers 400 W through a standard ATX form factor. It is intended for desktop builds that require a basic power source for everyday computing tasks. The unit has been tested working before shipment. It suits office PCs or entry-level configurations with modest energy demands.

Fits standard ATX chassis

The supply mounts in any case designed for ATX power units and connects to motherboards and drives with the usual cable set. No extra adapters or proprietary brackets are required for installation. It frees the builder from hunting specialised form-factor units. The 2024 listing date confirms current production availability.

Steady output for continuous use

Under sustained load the unit maintains its rated 400 W without relying on short-term peak ratings. Components are selected for stable voltage delivery across the 12 V, 24 V and 42 V rails during extended sessions. It is not suited for high-end graphics cards or multi-GPU arrays that demand substantially higher wattage. Builders planning heavy overclocks should seek a higher-capacity model.
