Compatible System Power

This 150W ATX power supply is built for specific KHACHIMO all-in-one and small-form-factor desktops including the E93Z, SB85, S740, S780 and S800 series. It uses a 14-pin connector and matches part numbers PS-2181-08, HKF1502-3D, APB003 and PS-2151-08. It is not for builders needing standard 24-pin ATX power or higher wattage for discrete graphics cards.

Sustained Load Behaviour

The 80 PLUS Gold certification means the unit maintains high efficiency across typical workloads rather than only at peak. Resonant LLC topology with DC-to-DC conversion delivers stable voltage rails during extended use, supporting modern standby sleep states without voltage drift. This design reduces coil whine when the system runs continuously at low or medium load.

Thermals Noise and Power

Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation. Gold-level efficiency lowers waste heat, keeping internal temperatures cooler during normal desktop tasks. The combination of efficient topology and fan-stop behaviour reduces both acoustic output and power draw in everyday use.

Questions about this item

How loud and warm does the 150W unit get after running all day?

The 80 PLUS Gold certification keeps power draw low, so the unit stays cool, and the Zero RPM fan mode stops the fan entirely at low and medium loads for silent operation.

What must I already own for this 14Pin PSU to work?

You need a compatible AIO chassis such as the E93Z, SB85, S740, S780, S800-10 or S850 that accepts the 14Pin connector.

Will this PS-2181-08 replace the older PS-2151-08 in my existing system?

Yes, the PS-2181-08 is listed as a direct replacement for the PS-2151-08 and fits the same supported AIO models.
