Compatible Dell T5500 and T5400 replacement
This 875W server power supply replaces the original unit in Dell Precision T5500 and T5400 workstations. It matches part numbers J556T, W299G, N875EF-00, H875EF-00, PS-875BB A and D875E001L. The unit delivers up to 875Watt total output for demanding professional workloads.
Check connector layout and rail limits
Verify that your existing workstation uses the same proprietary connector pinout before ordering. The supply provides +12V across four rails rated at 18A each, while +5V and +3.3V rails deliver 32A and 30A respectively. Ensure your motherboard power distribution matches these specifications.
No cables or software included
The package contains only the power supply module itself; no modular cables, mounting brackets or configuration utilities are supplied. You must reuse the original cabling and chassis hardware from the workstation. Installation is a direct hardware swap with no firmware updates required.

Questions about this item
Does the power supply ship with the cables needed for a T5500 or T5400, or must I source them separately?
The unit is a direct replacement module for T5500 and T5400 workstations and plugs into the system's native power backplane; no extra cables are required.
The listing shows several part and model numbers — which one should I match to my existing unit?
Match any of the listed identifiers — J556T, W299G, 0J556T, 0W299G, N875EF-00, H875EF-00, PS-875BB A or D875E001L — they all refer to the same 875 W module for T5500 and T5400.
What does the 875 W rating mean for the +12 V rails when the supply is installed in a T5500?
The four +12 V rails (VA through VD) each deliver up to 18 A, giving a combined +12 V capacity that supports the workstation's processors and graphics cards within the 875 W total limit.
