Optiplex 390 MT power supply change?

This question has suggested answer(s)

Will this power supply fit and work with my Optiplex 390 MT?

It has two PNY 4gb 667mhz ram, Western Digital 250GB HDD, and Intel Core I5-2400 3.1GHZ processor, with an H61 socket motherboard, as well as Optiplex 390 standard minitower case.


Also will a XFX Radeon HD 577X fit inside as well?  The original PSU is trash so I needed to replace so the computer does not die.

  • did this work for you? as i plan to change my power supply as well.

  • Yes, it worked perfectly with a 520 watt power supply by Dynex.  It was quite a snug fit and don't forget to hold the case lever while your inserting the power supply to make it fit.
