Ruth's sister M821J internal power cable

SKU CH-9ZCV-3DP5H

A 525 W non-modular server supply with 20-pin interface, four-pin CPU connector and two SATA ports for Dell Precision T3500 workstations

  • Delivers 525 W to power a T3500 workstation
  • Active PFC corrects power factor for stable 200-264 V input
  • Two SATA ports supply drives without extra adapters
  • 20-pin interface matches Dell Precision T3500 motherboards
  • Non-modular design keeps all cables fixed for simple installation

Replacement PSU for Precision T3500

This 525 W power supply fits the Dell Precision T3500 workstation and matches spare part M821J. It delivers 525 W from a 200-264 V input and uses active PFC. The unit is non-modular and carries an Other Certification 80 PLUS rating.

Direct swap for D525AF-00 and compatibles

It replaces the original D525AF-00, H525AF-00, U597G and X008G units without adapter cables. The jump is worth it when the existing PSU fails or when a rebuild needs a tested 525 W replacement that shares the same 20-pin main connector and 4-pin CPU plug.

Limited by 20-pin main and two SATA connectors

The 20-pin interface restricts use to motherboards designed for that layout, and only two SATA power ports are provided. No PCIe 12 V connectors are present, so discrete graphics cards requiring auxiliary power cannot be supported. Builds needing more drives or GPU power will need a different platform.

Questions about this item

What motherboard connector does the M821J power cable use?

The cable connects through a 20Pin interface that plugs directly into the workstation motherboard.

Which step is most often missed when fitting the M821J cable in a Precision T3500?

After seating the 20Pin plug, the 4 pin CPU power connector must also be attached or the system will not start.

When should the M821J cable be replaced if the 525W supply stays in service?

Replace the cable if the 20Pin or 4 pin connectors show discolouration, melted plastic or intermittent power delivery.
