I thought about it, but I was hoping that there is adaptor or something. Did anybody know if it exists.
ok here is how u do it. put the positive on the positive one then go to where the third one should be and put the other one on it leave the middle one open
Most motherboards mount the PW LED on three pins with the center one open.
What's the frequency, Kenneth?
Most AMD ones do, if you go to maplin or some such shop, you should be able to find a 3 pin plug. Its easy to take out the 2 wires from the current plug and put them in a 3 Pin one, at least they are in most of the cases i have built in.
This is the norm for motherboards, yes, even 386 Intel motherboards. You can cut down a 4 or more pin connector to 3 pins, lift the tabs to pull the wires out, and put them in the new connector.
