685W power supply for Precision T5810

This 685 watt server power supply is built for the Dell Precision T5810 workstation. It replaces the original unit using part numbers W4DTF, K8CDY, CYP9P, KTMT8 or VDY4N. The unit weighs 5.0000 pounds and carries model number 641329921043. It is supplied new with a 90 day warranty.

Suits T5810 owners needing a direct replacement

This supply fits only the Precision T5810 chassis and its proprietary connector layout. Builders working on other Dell workstations, custom towers or standard ATX cases cannot use it. Buyers who need redundant power modules or higher wattage for multi-GPU configurations should look at a different platform.

Verify the T5810 part number before ordering

Confirm that your workstation label lists one of the five part numbers above. Check that the existing power supply cable routing and latch mechanism match the replacement unit. Ensure the system firmware is current so the new supply is recognised at boot.
