This 850W high-efficiency workstation power supply is a direct replacement for compatible ThinkStation P500, P510, P700, and P710 systems originally configured with the 850W PSU option. The removable assembly features automatic input-voltage sensing, an integrated cooling fan assembly, rear extraction handle, IEC C14 AC inlet, a proprietary system backplane edge connector, and one separate 14-pin system connector. Part numbers 54Y8907, FSP850-0AWSE, and SP50A33624 identify interchangeable references for this assembly.

Part-Number Mapping: 54Y8907 is the FRU/service number, FSP850-0AWSE is the power-supply model number, and SP50A33624 is the LI part number printed on documented FSP production labels.
This power supply has an IEC C14 inlet and requires a power cord with an IEC C13 equipment connector. For standard North American 125V outlets, use the 5120P - 6FT 125V NEMA 5-15P to IEC C13 Power Cord.
The IEC C13 end connects directly to the power supply. Use a correctly rated and approved regional IEC C13 power cord outside North America.
Compatibility applies only to systems originally configured for this 850W removable PSU assembly. P500, P510, P700, and P710 workstations were offered with multiple power-supply wattages. Verify the existing PSU part number, wattage, physical chassis, backplane contacts, 14-pin connector, mounting profile, and rear handle before ordering.

✓ Confirm the original power supply is rated at 850W. These workstation families were offered with lower-wattage PSU options, and wattage alone does not confirm a direct fit.
✓ The assembly uses two system-side interfaces: a proprietary gold-finger backplane edge connector and a separate 14-pin connector. Both must match the workstation.
✓ The 14-pin connection is not a standard desktop 24-pin ATX motherboard connector. Do not attempt to install this PSU in a standard ATX chassis.
✓ No conventional motherboard, CPU, GPU, SATA, or peripheral power cables exit directly from the PSU. System power is distributed through the workstation’s proprietary internal power hardware.
✓ Confirm the rear extraction handle, metal housing profile, mounting guides, backplane contacts, and 14-pin connector against the original supply before installation.
✓ Do not purchase this unit solely because a workstation belongs to the P500, P510, P700, or P710 family. Confirm that the specific machine was built for the 850W PSU assembly.
✓ These workstation families were sold with multiple PSU wattages. This replacement is confirmed only for machines built with the corresponding 850W power hardware.
✓ Although the 14-pin connection and plug-in assembly are described as hot-pluggable, this is not a redundant live hot-swap server PSU. Shut down the workstation, disconnect the IEC C13 power cord, and allow standby power to discharge before removing or installing the supply.
