[SOLVED] Power Button doesn't work

I would still check your line voltage at your wall outlet. Most power transformers used by utility companies have multiple or variable "taps". Think of a tap as you would a beer keg or water "tap". The tap lets the electrician adjust the output voltage of the transformer by physically moving the tap to different points on the output winding of the transformer.
As seen in the below image of a simple transformer, the input is on the left and the transformer output is on the right.
Connecting the wires to the Negative and Positive terminals would be using the full output voltage capability of the transformer. But if they moved the output wire from the positive terminal to that tap terminal, the output voltage would be something less than full. On a large power transformer, there would be several of those taps, or the tap could be moved (variable) to obtain any desired output.
By checking the voltage at your wall outlet, you can verify the electrician set the output tap to the correct voltage.
I don't think that is your problem now. Sadly, it would seem your problem is either unrelated to your line voltage, or the damage was already done. Checking the voltage now to ensure it is correct will help ensure no additional damage to other electronics in the house.
An AC Outlet Checker like the one I linked too above in Post #8 is simple to use and will measure the voltage accurately and safely. Many of the better UPS have an LCD status display panel that typically show the input voltage, as do Kill A Watt meters, which as seen here, come in UK versions too. And since they too just plug in, they can be used easily and safely too. Last, if you know what you are doing, a simple voltmeter can be used to measure your line voltage too.

Thanks for the reply. Will do just as that. I think the damage was already done to the PSU, so I'll replace it, as I don't see any problems with the other hardware.

Update: Replaced the PSU and it is all good now. I have no other issues. Thank you everyone for the help.
