hey guys this is kind of a stupid question but i have a spare psu with a on of wires and a case that sits by my desk with nothing in it is is possile to plug the power supply strat the the fan with no mobo or anything it looks like i have the wires for it thanks for reading :)
Did you mean do you want to plug a case fan directly to the PSU's lead? It's possible if the case fan has a 4-pin molex connector. I modified 2 fans (80mm and 92mm) that had each a 2-pin connector to 4-pin molex. Selling those as it's too loud for me and I can't really get any more use out of them.
But anyways, it's possible.
