Compatible 180W ATX Replacement

This 180W ATX power supply replaces the original unit in compatible KHACHIMO systems including S700, S740, S780, S800, S850, B85 and E93Z models. It uses a 14-pin connector layout matching part numbers APB003, PS-2181-08, 54Y8883 and HKF1802-3D. The unit is new and intended for owners restoring or maintaining those specific desktops.

Sustained Efficiency And Quiet Operation

80 PLUS Gold certification means the supply maintains high efficiency across typical workloads, reducing waste heat and keeping internal temperatures lower during extended use. Resonant LLC topology with DC-to-DC conversion delivers stable voltage rails under continuous load while minimising coil whine. Modern Standby support allows the system to enter and exit low-power sleep states quickly without destabilising the power delivery.

Zero RPM Fan Mode And Proprietary Mounting

At low and medium loads the cooling fan stops completely, providing near-silent operation for office or media tasks. The 14-pin connector and specific form factor are proprietary to the listed KHACHIMO chassis, so the unit will not fit standard ATX cases or motherboards. Builders needing a conventional 24-pin ATX supply or higher wattage for discrete graphics cards should select a different product.

Questions about this item

How loud is the 180W APB003 when the Zero RPM fan mode engages at low load?

At low and medium loads the cooling fan stops completely, so the unit runs near-silently until higher power draw spins the fan up again.

Which motherboard connector does the 14-pin APB003 require to deliver power?

It uses a proprietary 14-pin ATX connector designed for compatible Lenovo S700, S740, S780, S800, S850, B85 and E93Z small-form-factor systems.

Will the 80 PLUS Gold APB003 work with an older Haswell-era CPU in a supported chassis?

Yes, the DC-to-DC topology and Modern Standby support provide clean power and efficient sleep states for older processors installed in the listed Lenovo models.
