I have read that there is a problem using older Dell PSU's with standard ATX motherboards, AOpen AX6B ATX MB in my case. From what I have read, there are some that say that doing this "could" kill the PSU or the MB or both. The Dell PSU in question came out of my Dell Dimension XPS b733r which I am sad to say, bit the dust yesterday due to my manhandling of memory insertion and spreading one of 2 mem slots. Anyway, I decided to harvest everything, including the PSU.
I have also read that in the Dell Pentium II and III, Dell uses a standard ATX PSU (200 watts) with an added 6 pin connector for the Intel motherboard's "Aux" power which it indeed had. My thought is that since the AOpen board does not have this additional connector, I just don't worry about it as the 20 pin connector should be fine to work. But, I do not want to fry my new (to me) AOpen MB. The DELL PSU fits like a glove into the 20 pin connector, but does have a missing pin, like pin 17/18 or pin 3/4 depending on how you look at it.
I can order a standard ATX PSU from a number of sources, 200-300w with all voltages, +12/-12, +5/-5 and +3.3 - like this one - https://www.ebay.com/itm/275799864531
If I can use the Dell PSU, that would be quicker and cheaper. Any thoughts would be greatly appreciated.
