My computer wont power on. it shows no sign of power at all.  I have tested the power supply with a PSU tester and the tester shows that the PSU is working properly. I also checked the cord for the power supply. I made sure all connectors were properly seated. the power button is connected properly.  the computer was working fine the night before.  I shut it down and when i went to turn it on the next day, nothing.  I am hopping its not the motherboard.  is there anyway its still the power supply even though the tester shows all the right voltage?

 

MSI Z97 G45 motherboard

I7 4770k

8gb ram

750w ultra PSU

That PSU is pretty sketchy IMO. It's quite possible it could've died. I'd recommend borrowing another PSU or using a spare if you have one and testing it with that. 

CPU: INTEL Core i7 4790k @ 4.7Ghz - Cooling: NZXT Kraken X61 - Mobo: Gigabyte Z97X SLI - RAM: 16GB G.Skill Ares 2400mhz - GPU: AMD Sapphire Nitro R9 Fury 4G - Case: Phanteks P350X - PSU: EVGA 750GQ - Storage: WD Black 1TB - Fans: 2x Noctua NF-P14s (Push) / 2x Corsair AF140 (Pull) / 3x Corsair AF120 (Exhaust) - Keyboard: Corsair K70 Cherry MX Red - Mouse: Razer Deathadder Chroma

Bit of an AMD fan I suppose. I don't bias my replies to anything however, I just prefer AMD and their products. Buy whatever the H*CK you want.

Well if you're completely sure everything is seated/plugged in properly and there wasn't a MAJOR hardware change or anything I'd say you should try to test it with another PSU.
