Unexpected Shutdowns - Possible power supply issue?

I built my PC about 11 months ago; in the past couple of weeks it has started shutting down while playing games or watching YouTube videos.

I have also noticed that there is a delay when I press the power button and the system starts (LEDs, fans, POST, etc.) Sometimes the power button is completely unresponsive but if I power cycle the PSU it will start to work.

I updated my BIOS about a week ago to see if that would fix the issue, but no luck. All graphic drivers are up to date as well.

I don't think it's a heat issue. CPU, MB, and GPU all idle around 30 degrees and rarely go above 50 under load.

After reading some other posts I am thinking it is the power supply, I'd just like to get some other opinions before buying a new one.

Intel i5 4670K @ 4.2 GHz
Cooler Master Hyper 212 EVO
Asrock Z87 Extreme4
Gigabyte GTX770 2GB
Corsair CX750M
8 GB RAM (sorry, can't remember the brand?)
Samsung EVO 500GB
Rosewill Challenger-U3 case
Windows 7 Home 64-bit

Let me know if you need any other info.

Thanks for the input!

Thanks, I looked up some reviews and saw that others were having the same issue with the power supply. Do you have any recommendations for a more reliable one?

I have been able to get it booted but it seems like it takes the power button a long time to respond. There is usually a noticeable delay after I press the power button, and sometimes I have to turn the power supply off and back on before I can boot the PC.
