I have two computers dating back to 95 or so (1 200 MHz Pentium II MMX, 1 200 MHz Pentium Pro) with bad power supplies. I note that the main power connector for each of these is different: one has a single big plug (2x10, 20 pins), while the other has two smaller plugs. What's the terminology for each of these, so I know what power supplies I should be getting?

The 20pin is an ATX connection. The "two smaller" plugs are most likely AT from your description. The newer of the two is ATX.

<< How do you know that the power supplies are bad? >>



Both are "bad" due to fan failure from excessive dust buildup. One actually has a two-pin plug for the fan, so if I can find a 90mm fan with a 2 prong plug I should be good to go. The other has the fan wired into the supply, and my electricial skills aren't up to the task of connecting the wires to a new fan.
