Part Number: D15‑1K0P1A
Also known as: 851383‑001, D1K0E001H — all refer to the same 1000 W PSU used in certain HP workstations.

Key Specifications

Maximum Output Power:

• 1000 Watts total capacity.

Form Factor:

• Internal workspace PSU, ~214 mm deep, ~120 mm wide, ~86 mm tall. 

Connectors:

• Main 18‑pin motherboard connector
• Additional 12‑pin power

Compatibility

This PSU is designed for specific HP workstations:

• HP Z4 G4 Workstation
• HP Z6 G4 Workstation 

It may physically fit and electrically match only these chassis variants — standard desktop ATX cases and server chassis are not guaranteed without adapters. This PSU is not a generic ATX PSU. 

Important: HP workstation PSUs use proprietary connectors — you usually cannot swap a generic PSU into the workstation, nor easily use this PSU in a standard desktop without special adapters or custom wiring. 

Use Cases

• Full‑power replacement for Z4/Z6 G4 workstations
• Ideal for systems with multiple GPUs or heavy CPU loads
• Stable wide‑range input suitable for global use
