    Default Dell Optiplex GX1 proprietary PSU swapout

    So the long and short of it is a Have 2 Dell Optiplex BX desktop systems. I have had one since about 2000 and the other I was given a couple years back. A systems controller at work was actually still (its quite modern) using a dell GX1 and the PSU blew. I volunteered mine as a temp replacement till the vendor could supply one. Since the machine is 20 years old they swapped it for a rack mount PC instead. They ended up giving me the gx1 sans hard drive and caddy and psu.

    I love this machine, its built like a tank. Never really was or am a big dell fan but this machine has stood the test of time and continues to impress me. It was my WEP cracking box for a while and its my win 9x/DOS floppy drive workstation.

    I would really love to get the second one up and running as another DOS machine but I know the PSU is proprietary.

    Now stop me if this thread exists elsewhere but Id rather not pay the $20+ for a psu if I can alter another ATX to work. Does anyone have experience in this area?

    Any advice would be appreciated.

    P.S. If anyone has a spare hard drive caddy for this model (think the part number is 59602) PM me

    I found this article from way back giving some insight to the issues. It lists a couple tables and pinouts:

    With this info and a pin pop-tool would it be as easy as just popping out the pins and connecting them in the right ATX standard layout?
