400W ATX Power Supply

The KHACHIMO PWS-401-1R is a standard ATX power supply rated at 400 watts. It is intended for desktop builds that require a basic, tested unit for everyday computing tasks. The supply suits office workstations, home PCs or replacement scenarios where extreme power headroom is not required.

ATX Form Factor Limits

The ATX form factor fits most conventional tower and desktop chassis designed around the standard mounting pattern. Builders using slim, small-form-factor or proprietary cases may find the unit physically incompatible. The interface provides the usual motherboard and peripheral connectors defined by the ATX specification.

400W Capacity Headroom

A 400W rating comfortably handles mainstream CPUs, integrated graphics and a modest complement of drives and memory. Systems equipped with high-end discrete graphics cards, multiple storage arrays or heavy overclocking will exceed the available headroom. The unit is tested working and built to a good quality standard for its rated output.

Questions about this item

How do I decide between the 400W capacity and other wattages?

The 400W rating is the maximum continuous output; choose it when your total system draw under load stays below that figure.

What does the 400W headline figure mean once the unit is installed?

It guarantees up to 400 watts of combined DC power across all rails for your components.

Which ATX standard does this supply follow and what does it cap in practice?

It follows the ATX form factor, so it fits standard cases and caps output at the labelled 400 watts.
