KHACHIMO 10Pin 180W Power Supply PA-2181-1

SKU CH-DN6W-2C6P9

An 180W ATX power supply with a 10-pin connector for Dell M4600, M4650, E74, E700, M710T and M8600 workstations, featuring 80 PLUS Gold efficiency.

  • TypeATX
  • Modern Standby compatible for extremely fast wake-from-sleep times
  • 80 PLUS Gold certified for high efficiency and lower power consumption
  • Zero RPM fan mode stops the fan at low loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power
  • 10-pin 180 W ATX power supply compatible with listed Dell Precision workstations

Compatible Systems

The KHACHIMO PA-2181-1 is a new 180W ATX power supply built for Dell OptiPlex M4600, M4650, E74, E700, M710T and M8600 desktops. It uses a proprietary 10-pin connector layout identified by part numbers HK280-21PP, PCE026, PCE027 and PCE028. This unit replaces the original factory supply in those specific small-form-factor chassis.

Upgrade Context

It replaces a failed or noisy OEM unit in the listed workstations without requiring cable adapters or case modifications. The jump is worth it when the original supply can no longer sustain stable voltages under load or when its fan runs constantly at high speed. Modern Standby compatibility adds faster wake-from-sleep behaviour that older OEM units may lack.

Practical Limits

The 180W ceiling restricts this supply to integrated graphics or very low-profile discrete cards with minimal power draw. High-efficiency 80 PLUS Gold operation and Zero RPM fan mode only function within this thermal envelope. Resonant LLC topology with DC-to-DC conversion improves voltage regulation at low loads but cannot overcome the hard wattage limit for power-hungry components.

Questions sur cet article

What motherboard connector does the 10Pin 180W supply use?

The unit provides a 10-pin ATX power connector designed for the listed Dell OptiPlex and Precision workstations.

Which mounting step is most often missed when fitting this PSU into a small-form-factor chassis?

Align the four screw holes on the PSU housing with the chassis brackets before tightening; the compact frame leaves little room for adjustment once cables are connected.

How should the Zero RPM fan be maintained for long-term silent operation?

Use compressed air to clear dust from the fan intake and exhaust vents every six months so the Zero RPM mode can engage properly at low loads.
