240 W ATX power supply for compact builds

The KHACHIMO IUPS-401 delivers 240 W of continuous power in a standard ATX form factor. It carries 80 PLUS Gold certification for high efficiency at typical loads. Modern Standby compatibility enables rapid wake-from-sleep transitions. Resonant LLC topology with DC-to-DC conversion provides clean, stable output rails.

Suitable for low-power desktops and office systems

This unit fits small-form-factor PCs, basic workstations and refresh hardware that stays well within a 240 W envelope. Zero RPM fan mode keeps acoustics near silent during light workloads. Builders targeting mid-range or high-end graphics cards should look at higher-wattage units. Systems requiring multiple drive arrays or heavy overclocking headroom will exceed the rated capacity.

240 W rated output

The single specification that decides fit is the 240 W maximum continuous power rating. Match this figure against the total combined draw of your CPU, graphics card, drives and peripherals. If the calculated peak load approaches or surpasses 240 W, a larger supply is required. No other metric in the data overrides this limit.

Questions about this item

Which motherboard power connectors does the IUPS-401 provide for an ATX build?

The unit follows the ATX form factor so it includes a 24-pin main connector and a 4-pin or 8-pin CPU power connector for standard motherboards.

Will the 240W output and Modern Standby support work with an older board that only has legacy sleep states?

Yes, the supply delivers up to 240W and its Modern Standby design is backward compatible with traditional S3 sleep on older motherboards.

How can I confirm the Zero RPM fan mode is active after I install the PSU?

Under light loads the fan stops completely; you can verify by listening for silence and checking that the 80 PLUS Gold efficiency rating is met at low power draw.
