Hmm...I missed out this portion. "I was unable to reset using button I had to shut down by turning off power supply" It is very weird that you can't reset using the reset button. It is not possible, because the reset button is directly connected to the motherboard. The function of the PSU is pretty simple. It supplies power. There's only a few occasions that I encounter PSU issue were, the PSU blew up, and my 480W PSU couldn't take it when I try to SLI 2 highend Nvidia. If the PSU was still supplying power at that time, I would rule out the PSU. But since this is an isolated case, I won't bother to investigate further. Do take more note when it happens again.
BTW, if you face this problem again, you don't have to turn off the PSU directly, unless that's convenient. You can also press the power button for 4 seconds or longer. That should power down the PC.
