No fan, moves a turn or two, I know that the power connections good. Thanks, >> heres a quick and dirty way to test one: if you have a hard drive, plug that into one of the power connectors, then hit the switch. that will let you know if its working or not. this test will work, as i use an xt supply just to run a scsi drive for my mac when i bring it out for testing once in a while. if not working, i have several extra xt supplies i need to get rid of. message me privately if interested. david
