  • 265 W output powers OptiPlex 390, 790, 990, 3010 MT
  • Genuine Dell unit replaces GVY79, 053N4, YC7TR, D3D1C, 9D9T1
  • Mini-tower form factor fits listed chassis only
  • New condition ensures full rated performance
  • Direct replacement avoids compatibility guesswork

Compatibility

This 265 watt Dell power supply fits the Mini Tower chassis of the Optiplex 390, 790, 990 and 3010. It replaces part numbers GVY79, 053N4, L265AM-00, YC7TR, D3D1C and 9D9T1. The unit is supplied new or as unused old stock. Buyers with small form factor, ultra-small or all-in-one Optiplex models cannot use this PSU.

Form-factor limit

The supply is built only for the Mini Tower version of the listed desktops. Other chassis sizes use a different mechanical layout and connector arrangement, so this unit will not install in them. No adapter or bracket is mentioned in the data. Shoppers who need a replacement for a non-MT Optiplex must source the correct form factor.

Power headroom

Rated at 265 watts, the unit delivers the original factory power budget for the compatible Optiplex towers. It supports the standard components those systems shipped with. Configurations that add high-wattage graphics cards, extra drives or heavy overclocks will exceed this capacity. Builders planning such upgrades need a higher-output PSU.
