Compact 1U ATX power supply

The KHACHIMO HKI050-120NB is a 1U form-factor ATX power supply rated at 12 V and 4.2 A. It targets compact workstations and small-form-factor builds that need a certified efficient unit in a slim chassis.

50 W continuous output with Gold efficiency

The unit delivers 50 W of continuous power on the 12 V rail, suitable for low-draw CPUs and integrated graphics. Headroom is limited; systems with discrete GPUs or multiple drives will exceed the available capacity.

Zero-RPM fan mode and LLC topology

At low and medium loads the cooling fan stops completely for near-silent operation. Resonant LLC topology with DC-to-DC conversion reduces coil whine and supports modern standby sleep states for cooler, quieter running.

Questions sur cet article

Will this 12V 4.2A unit power an older ATX motherboard that still needs a 20-pin connector?

The supply follows the ATX form factor so it will fit the same mounting holes and provide the standard 24-pin main connector; the extra four pins can be left unplugged on a 20-pin board.

How can I confirm the Zero RPM fan mode is active after I install the HKI050-120NB?

Under light load the fan should stay completely still; you can verify by watching the fan through the grille or by listening for silence while the system idles.

Does the box include the IEC power cord and mounting screws for a 1U chassis?

The unit ships with the power supply itself; the IEC mains cable and 1U mounting screws are not included and must be sourced separately.
