Compatible Dell Workstation Models

This unit fits Dell Precision M4600, 4650, M4200f, M4900 and T6900c systems. It replaces part numbers PA-2181-1, PCE027, PCE028, HK280-22PP and HK280-21PP for direct installation. Builders servicing other chassis or proprietary form factors cannot use this supply.

Build Quality and Connector Layout

The 10-pin connector matches the Dell workstation pinout for a secure fit without adapters. ATX internal topology includes resonant LLC and DC-to-DC conversion to reduce coil whine and support modern sleep states. A zero-RPM fan mode stops the fan at low and medium loads for quieter operation.

180 W Output Limit and Efficiency Class

Rated at 180 watts, this supply suits configurations that stay within that power envelope. The 80 PLUS Gold certification confirms high efficiency at typical loads, lowering consumption and heat. Systems requiring more than 180 W or a different connector pinout need a different unit.
