Replacement Power Supply for Select Dell Systems

This 365W proprietary power supply replaces Dell part numbers T1M43, 7VK45, D365EM-00 and HU365EM-00. It is designed as a direct replacement for Optiplex 3020, 7020 and 9020 desktops, Precision T1700 workstations and PowerEdge T20 servers. The unit fits only models that originally shipped with a 365 watt power supply.

Suitable for Restoring Factory Power Delivery

Buyers restoring a listed Dell system to original specification will find the correct connector layout and rated output. This supply is not for systems that shipped with a different wattage unit, nor for standard ATX chassis builds requiring industry-standard pinouts. Builders needing higher capacity or modular cabling should look elsewhere.

Steady Output Under Continuous Load

Rated at 365 watts, the unit delivers consistent power during extended workstation or server workloads rather than only brief peaks. Thermal management follows the original Dell design for the supported chassis. Stability is maintained across the supported Optiplex, Precision and PowerEdge platforms during sustained operation.

Questions about this item

Does my Dell Optiplex 3020 need to have shipped with a 365W unit for this T1M43 supply to fit?

Yes, this replacement is only for models that originally came with a 365 watt power supply; other chassis use a different form factor.

Can I reuse the cables from my old 7VK45 power supply with this 365W replacement?

The unit is a direct swap for part numbers T1M43, 7VK45, D365EM-00 and HU365EM-00, so the existing proprietary connectors match.

After installing the 365W supply in my Precision T1700, how do I confirm it is delivering power correctly?

The system will complete POST, the front power LED stays solid amber or white, and the operating system loads without unexpected shutdowns.
