HP ProDesk PCH021 PSU Power Supply 180W (USED LIKE NEW)
The HP ProDesk PCH021 180W power supply is a compact internal SFF power module engineered to fit HP ProDesk 400/600 small-form-factor desktops. It is intended to deliver a single-rail high-current DC output while occupying minimal chassis space, so system designers can keep overall PC volume small without sacrificing baseline power capacity for CPU, storage and basic expansion cards.
Mechanically the unit is built for OEM integration: a slim rectangular metal housing with factory connector harnesses that mate directly to the ProDesk motherboard connectors. The internal design balances thermal management and acoustic behavior so that the PSU sustains continuous office workloads while fitting inside constrained airflow compartments typical of SFF cases.
In real-world use the PCH021 provides a predictable power envelope for business desktops smoothing startup surges, supporting short current spikes and keeping system voltages stable during platform activity. Because it’s a standard replacement part for several ProDesk generations, IT teams can swap or refurbish these PSUs quickly to restore service with minimal downtime.
Features:
- Compact small-form-factor (SFF) internal power module for ProDesk systems.
- Single high-current DC output optimized for desktop loads.
- Wide AC input range for global compatibility.
- OEM connector harness (multiple onboard connectors) for direct motherboard fit.
- Designed for continuous office duty in constrained chassis environments.
