⚙️ Fit Notes
- Match your original wiring harness part number whenever possible
- Confirm your original harness is marked or identified as YN945
- Confirm your system is a Precision T5400 using the compatible 875W power supply family
- This harness is intended for the GM869 / H875E-00 / HP-D8751A001 / N875E-00 / NPS-875ABA / YN642 875W PSU family
- This listing is for the wiring harness only
- Power supply is not included; use the compatible GM869 875W power supply if needed
- This harness is not a universal ATX power cable set
- Do not use with different workstation models, different PSU wattages, or different PSU connector layouts unless the original harness part number and full connector layout match
- Compare the large PSU connector, white motherboard connectors, black auxiliary power connectors, SATA power connectors, 4-pin peripheral connector, small auxiliary leads, cable lengths, routing points, clips, and branch locations before installation
