Well I just installed my new Ultra x2 PSU and it does start up but the first screen sais, "System fan failed". Can't figure out how to get it to pass. please help me!
It'll be a tiny 3-pin. If you have an old mobo, you'll need to buy a 3-pin to 4-pin adaptor.
EDIT: Just looked at a pic of the wires that come with that PSU, and it comes with an adaptor. The wire you're looking for is the cable composed of 2 wires.
I believe you are talking about the cable that goes from a 4 pin (only 2 prongs in it) to three 3 pins (which only have 2 prongs inside them)...I don't understand how to use them
