Compact 1U ATX power supply

The KHACHIMO 1U 12V 450W unit fits 1U rack and small-form-factor chassis that accept ATX-type supplies. It targets builders who need server-grade density without sacrificing efficiency certifications. Buyers requiring redundant or hot-swap power modules cannot use this single-unit design.

Build integration and thermal behaviour

The supply delivers 450 W from a single 12 V rail using resonant LLC topology with DC-to-DC conversion for tight regulation. Zero RPM fan mode stops the fan at low and medium loads, reducing acoustic output in noise-sensitive deployments. Modern Standby compatibility enables rapid wake-from-sleep transitions for always-on edge or workstation roles.

Efficiency certification and operational impact

80 PLUS Gold certification confirms high efficiency across typical load ranges, lowering electricity draw and waste heat. The combination of Gold-rated efficiency and fan-stop behaviour reduces cooling demand in dense racks. No modular cables or software monitoring utilities are mentioned in the supplied data.

Questions about this item

Will the 450 W rating hold under continuous full-load operation in a 1U chassis?

The unit is rated at 450 W with 80 PLUS Gold efficiency, so it can sustain that output continuously within its thermal design.

How loud does the fan get when the supply runs at high load all day?

Zero RPM mode keeps the fan off at low and medium loads; under sustained high load the fan spins up but the resonant LLC topology and DC-to-DC conversion are designed to minimise coil whine and acoustic noise.

Which ATX cables or motherboard connectors must already be present for this 1U supply to work?

It uses the standard ATX pinout, so a motherboard with a 24-pin main connector and the required 12 V CPU power connector is all that is needed.
