Psu for lga 775 motherboard

[Cdog042501]

I have an old optiplex runing a pentium 4ht on the 775 chipset i was looking to build a retro type gaming system however i have struggled to find a psu that works it uses a regular 24 pin from a modern cpu but a different 4 pin connector as i used my new psu and an older psu with a 20 pin to power and check the system to confirm it was a bad psu thx for the help

Some of the older optiplexes used a "proprietary" psu where they just swapped the pinout. But lga 775 is so old you can find core 2 duo or quad pcs (entire tower) for $50. No reason to buy just the psu when you can get a whole old pc if that's what you want to run.

If you have the Optiplex 745 MT It can be upgraded to Core 2 65nm 1066fsb CPUs including extremes. It can be overclocked some also. if it's older than that I would get somethig else.
