Have you checked the power-outlet with another device?

Does the PSU have a power switch?

Does the PSU have a fuse?

Have you double-checked the connection to the power button?

Have you tried switching on the machine by manually bridging the power-button connector on the mainboard? Maybe the cases power button is busted somehow.

Another device = like a lamp or a radio.

And this is the connector I mean:

do you have it set up as specified in the mainboard's manual? And if you do, try to unplug it again and bridge the two pins with a screwdriver to switch the computer on

... carefully please. You can't harm your computer by touching the adjacent pins, but you do not want to slip and smash your screwdriver on the PCB.

you said it turns on but doesn't turn off? make sure that you have the 8 pin power along with the 24 pin cable connected to the motherboard. you can try testing the psu.
