HP DPS-475CB-1A Workstation Power Supply 475W (USED LIKE NEW)
The DPS-475CB-1A is a 475 W internal power supply module designed for HP Z-series workstations such as the Z400 and Z440. It serves as the primary AC-to-DC conversion unit within these systems, delivering stable power across multiple DC rails to support workstations running high-performance components like graphics cards, multi-core CPUs and multiple drives.
Mechanically built for workstation integration, the unit features a compact form factor that fits into HP’s proprietary chassis modules, with the necessary connectors and form-factor to match the factory implementation. The supply includes an 80 PLUS Bronze style efficiency rating, helping reduce heat and power wastage in heavy-load operations such as rendering or simulation.
In day-to-day use the DPS-475CB-1A provides the backbone power base for a workstation environment supporting bursts of GPU/CPU load, ensuring quiet thermal operation in a sealed chassis, and maintaining reliability under continuous uptime demands. For system builders and IT service teams, its modular design means faster replacement and predictable performance in HP’s workstation ecosystem.
Features:
- 475 W rated capacity for workstation power demands.
- 80 PLUS Bronze-class efficiency for better energy utilization.
- Internal module design matched to HP workstation chassis.
- Multiple DC rails (including dedicated GPU/CPU rail) to handle mixed load.
