I recently started putting together an old PC to give to my little brother. It was my main PC up until March of this year, and it has been sitting under my desk turned off ever since. Whenever I try to boot the PC with a HDD or SSD connected to the motherboard and PSU, the computer does not post. The CPU and PSU fans spin for about 1/2 of a second and then stop. If I have no drives connected to the SATA ports on the motherboard, then the computer boots normally into the bios. I have tried multiple SATA data and power cables. I have tried removing the GPU to see if the fans would continue to spin with the GPU completely disconnected and they would not. I have noticed that when the SATA power connector is connected an SSD and not the motherboard, when the PC turns on the cable gets very warm. I have tried two 2.5 inch HDDs and one 2.5 inch SSD. The PSU is new and pretty highly rated on Newegg, but I have not put it through intensive testing. Part of me suspects the PSU because of the warm power connector (when it posts and the SATA drive is not connected to the mobo), but everything seems to work well when no SATA devices are connected.

Thanks!

I finally fixed it. I was using a SATA cable that was provided with a different PSU and the inactive port of the six pin cable was different for a Thermaltake PSU compared to a EVGA.
