Question Is the PSU dying

[General_havy]

HI!
So for the last few days i have been having problems with my PC not starting properly. The fans spin but the PC doesn't start, and i have to shut it down and turn it on again. Also today i tried to play R6S with friends and my Pc suddenly crashed. First i thought it overheated, but as i had recently cleaned it i was skeptical and monitoring the temperatures in game they seemed normal CPU around 50 and GPU around 75 Celsius. Afterwards i ran a stress on both the GPU and CPU seperatly and everything worked fine. Than i decided to try to test both at the same time in AIDA 64 and after a second or 2 my PC crashed. I tried it again with the same results. Now i believe that indicates that my PSU is falling. IT is a few years old at this point. It is a no thrills Cooler master 600W 80 plus bronze one. But i just wanted to hear your opinions if it might be something else worth checking out before buying a new PSU since i do not have a spare one to test it.
Thanks in advance.

PC SPECS:
CPU: Ryzen 1600
MOBO:Gigabyte b350m gaming 3
Ram Kingston 16gb 2666hz cl16

I agreed, it sounds like PSU are bad.

However, I'd advice to take a look at the mainboard and see if any of the capacitors looks like begin to "boil over".
