I picked up an Ablecom SP645-PS a while back and I was just getting around using it. I was told it worked fine and have no reason to not believe the person in question. However upon taking the PSU out and looking at it there is no power switch on it. How do I turn it on? Tried hooking it up to my tester and an old mother board but no go. Look at some others online (I believe its the same thing as Supermicro PWS-0060 as well as some others. It in fact has the sticker on it) and they seem to have an on/off switch. I am aware that I am probably being a dumb ass here but I have never actually ran into this problem before.
