My user name says it all - getting too old for this stuff. Got a V71 full tower and moved my ASUS mobo, Antec PSU, HD's etc to their new home - went fairly smoothly 'til I got to the three pin from the rear exhaust fan and the two pin black Molex sticking through the grommet next to the drive bays. With power into the back of the PSU and a click of the power switch on top all I get is the red LED next to 24 pin power connector on the mobo. No fans, case LED's - nothing. What didn't I do? Almost forgot. I connected the 3 pin from the rear exhaust fan to the fan 4 pin on the mobo - it had a little guidance piece so slid right on. The 2 pin Molex went to a 4 pin female from the PSU.
