  • Delivers 300 W for stable desktop operation
  • Fits OptiPlex 390, 790, 990, 3010, 7010, 9010 MT large chassis
  • Includes 24-pin, 4-pin and four SATA connectors
  • Passive PFC design keeps circuit layout simple
  • Compact 150 x 140 x 86 mm form factor

Compatible desktop replacement

This 300W unit is built as a direct replacement for OptiPlex 390 790 990MT and 3010 7010 9010MT large-chassis desktops. It matches the original part numbers GVY79 053N4 9D9T1 X9GWG VK8VC 8TXFY and ships brand new after individual testing. Buyers needing a different form factor or proprietary server pinout should look elsewhere.

Capacity and headroom

The supply delivers 300W maximum output through a single 12V rail with passive PFC. Four SATA connectors support multiple drives while the 24-pin and 4-pin motherboard leads cover standard ATX needs. Systems requiring multi-channel 12V distribution or higher peak wattage will exceed this design.

Build and connectors

A 24-pin main connector and 4-pin CPU plug sit alongside four SATA power leads in a fixed cable layout. The housing measures roughly 150x140x86mm and fits the large OptiPlex chassis without modification. No modular cables or redundant hot-swap features are included.

How can I verify the power supply is operating correctly once installed?
