PSU power surge then PC won't boot - is my PSU or motherboard broken?

So I was playing rust when my PC just shut off.

I boot it back up, it displays that it had a power surge but all seems fine and I start playing again, after about 10 minutes it shuts off again - this time it won't boot up. Nothing...no fans move or anything. There is a light on my GPU that is on and a green light at the bottom of my MOBO but there's usually a large orange LED on the left of my motherboard that isn't on (I'm really scared it may be my MOBO).

I have unplugged it for 2 hours and tried again but it's still dead so can't be due to heat as I have a total of 10 fans in my PC.

I'm convinced (more hoping) that it's my PSU that is dead so someone please give me an insight into what is going on here.

Specs:
CPU: i5 6600k
GPU: GTX 950
RAM: 8GB DDR4
MOBO: ASUS Z170-P
PSU: Crappy ATX 500w (I know, it's from my first build, don't know why I didn't change it) which is why I think it's my PSU, surely my motherboard wouldn't get fried due to it being modern (it must have protection right?)

Please ask any questions as I've probably done an awful job at explaining everything. From what I've read it seems to be the PSU but some other threads hint at it being the motherboard - please help! D:


-one thing I forgot to add:
I noticed that the "Speaker" connected to the MOBO for the boot noise is broke (the circle thing has snapped off from the wires, not sure how but could this have any effect on my PC? Doubt it but figured I best put it out there in case.

Recommend don't use the PC until you get other good PSU.

Before you get the PSU, you can test the gtx950, RAM, HDD/SSD in other PC if you have. Just make sure they are fine.

After you get the PSU, boot the PC with minimum hardware, like no gpu, boot device, RAM, only using the onboard intel iGPU. If the PC can boot but you get no RAM, no boot device errors, that means the cpu/mb are fine, and add the hardware back to boot the PC.
