850W 80 Plus Platinum Power Supply for ThinkStation P500 P510 P700 P710 Workstation

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.

⭐ Recommended C13 AC Power Cord - Sold Separately

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.

✅ Confirmed Compatibility

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.

✔️ ThinkStation P500 Types 30A6 and 30A7: Compatible configurations originally equipped with the 850W automatic voltage-sensing power supply
✔️ ThinkStation P510 Types 30B4 and 30B5: Compatible configurations originally equipped with the 850W automatic voltage-sensing power supply
✔️ ThinkStation P700 Types 30A8 and 30A9: Compatible configurations originally equipped with the 850W automatic voltage-sensing power supply
✔️ ThinkStation P710 Types 30B6 and 30B7: Compatible configurations originally equipped with the 850W automatic voltage-sensing power supply

⚙️ Fit Notes

✓ 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.
