I know this is an old one but I have the same problem. I have a Corsair CX600M PSU and tried the test. The fan did not turn on. I have a Roswell Extreme RX750-D-B PSU I borrowed that is working and no power at all. I think the MB is bad. I am using the on board DVI for video. I could not find and separate on board GPU power connection on the MB.
EDIT: I wanted to post an update. I did get the power supply to run. http://
So the PSU suddenly ran for the test and then I got it to powered up the computer. I did not have the drives connected so I went into CMOS. I shut down and started up twice with no drives. Connected the drives and then no power. Odd is when it first worked for the paperclip test it was connected for about 3 seconds before it started. I think it is the power supply but tried a working Rosewill with the paperclip test and no power.. Not sure if the MB or drives fried the power supply.
