KHACHIMO 250W ATX power supply

The KHACHIMO PC40N250EV is a 250W ATX power supply built for compact or low-power desktop systems. It carries 80 PLUS Gold certification and uses resonant LLC topology with DC-to-DC conversion to deliver clean, consistent power. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. A Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent operation.

Best for quiet, low-power builds.

This unit suits builders assembling small-form-factor PCs, office workstations, or secondary machines where low noise and efficient idle power matter. The fan-less mode at typical loads keeps acoustic output minimal. It is not for systems with discrete graphics cards, multi-core overclocked CPUs, or any configuration that will draw sustained power above the rated 250W output. Buyers needing headroom for future GPU upgrades should look at higher-capacity units.

250W continuous output decides fit

The single specification that determines compatibility is the 250W maximum continuous power rating. Add the expected peak draw of every component — CPU, motherboard, drives, fans, and peripherals — and confirm the total stays comfortably below this limit. If the calculated load approaches or exceeds 250W, this power supply cannot support the build and a higher-wattage model is required.

Questions about this item

What does the 250 W rating mean for a typical desktop build?

The 250 W rating is the maximum continuous power this unit can deliver across all rails, suitable for office PCs or compact systems with integrated graphics and modest CPU power draw.

How does the 80 PLUS Gold certification affect daily operation?

Gold certification confirms high efficiency at typical loads, which lowers electricity use, reduces waste heat and lets the fan stay off longer in Zero RPM mode.

Will this ATX unit fit my standard desktop case?

It follows the ATX form factor, so it mounts in any case designed for a standard ATX power supply using the usual four rear screws.
