400W ATX power supply

The KHACHIMO ENR-1240 is a 400 watt ATX power supply built for desktop computers. It uses a switching topology to convert mains electricity into the DC rails required by internal components. The unit was first listed by the manufacturer on 12 March 2024 and ships in new condition. Each unit is test working before dispatch.

Entry-level desktop builds and replacement units

This power supply suits builders assembling a basic office or home PC with modest power requirements. It also fits as a direct replacement for a failed ATX unit of similar capacity in an existing chassis. Systems that demand higher wattage for discrete graphics cards, multiple drives or overclocked processors should look at a higher-capacity model.

400 watt total output

The single specification that decides fit is the 400 watt maximum power rating. Add the expected peak draw of every component — CPU, graphics card, drives, fans and peripherals — and confirm the total stays comfortably below this figure. If the calculated load exceeds 400 watts, this unit cannot support the build.

Questions about this item

How loud and hot does the KHACHIMO ENR-1240 get when running continuously at 400W?

The 400W ATX unit is tested working before dispatch; fan speed and thermal output will vary with actual load and case airflow.

Which power connectors must my build already provide for the ENR-1240 to function?

A standard ATX motherboard with a 24-pin main socket and a 4-pin or 8-pin CPU power header is required.

Will the 2024 ENR-1240 power an older motherboard that still uses a 20-pin main connector?

The supply follows the ATX form factor with a 24-pin plug; a 20-pin board would need an adapter not included.
