Compact 1U ATX power supply

The KHACHIMO AIO delivers 250 W of continuous power in a 1U form factor that fits small-form-factor chassis and rackmount builds. It targets system integrators and home-lab owners who need an ATX-400 compliant unit for space-constrained enclosures. Builders requiring higher wattage for discrete graphics cards or multi-drive arrays should look elsewhere.

Efficiency and acoustic features

80 PLUS Gold certification means lower wall draw and less waste heat at typical loads. Zero RPM fan mode stops the fan completely at low and medium loads for silent operation. Resonant LLC topology with DC-to-DC conversion reduces coil whine and supports modern standby sleep states for faster wake times.

Installation notes

The 1U height matches standard rack rails and shallow cases, but cable routing space is tight behind the connector panel. Verify that your motherboard's 24-pin and CPU power headers are reachable with the supplied cable lengths before closing the chassis. No modular cables are included, so unused leads must be tucked away carefully.

Questions about this item

Will the cooling fan need replacement after continuous use?

The Zero RPM Fan Mode keeps the fan off at low and medium loads, reducing wear and extending the fan's service life under typical operation.

What limits sustained output before protection engages?

The unit delivers up to 250 W continuous power; exceeding this triggers over-power protection to prevent damage.

How loud and hot does it get during all-day operation?

80 PLUS Gold efficiency and Zero RPM Fan Mode keep noise near-silent at typical loads while lower heat output maintains cooler chassis temperatures.
