Question PC randomly restarts when playing high-intensity games.

A few years back I got this pre-built pc and have been using it since with little to no issues. Recently I upgraded the motherboard CPU and RAM. It was working fine the first couple of weeks but recently it has started shutting off and going straight to boot when in the middle of a game, no bluescreen or audio hang. This only happens when I'm playing high-intensity games such as Destiny 2 and Apex Legends. It has not happened when playing any other games including Overwatch and League. I regularly check the temperatures while gaming and it doesn't seem to be overheating, even under a heavy load, everything is staying under60-70c.

what is your power supply and what are your new upgrades?
if the CPU or the GPU are needing more power than the PSU can provide during a game, reboot.
as it is happening in games its not random, only when under load which again points to the PSU.

Cypberpower skimps on the PSU, the smart is not a good unit. only 504 actual watts, not even bronze efficiency.
both CPU's are 65W, the GPU is the same and the power draw from the RAM should not be enough to trigger reboots.

if you can get hands on a spare PSU for testing the PSU question will be answered in short order. swapping is the next step.

My canned random reboot Rant
Random reboots are usually caused by the PSU, the RAM or software AND in that order of likely-hood.
PSU - If you can borrow/swap a PSU for testing. sibling/friend you can swap out the PSU and each system will be testing the other.
RAM - run the system with one stick of RAM see if stability returns if not Test all the RAM with memtest 86 for five passes or overnight. if you get no 0 errors after more than five passes the ram is good. with the random reboots I would suggest running this test after the PSU swap or after the PSU has been cleared.
Software - Drivers or other issues can cause reboots. Boot to a linux distro on a USB drive. mint linux will boot to memtest86. you can run the OS from the USB and await reboot.
end canned rant

Okay. I'll run the RAM tests and see about swapping out the PSU. Would it also be worthwhile to put my old Motherboard and CPU back in with the new RAM and see if the problem stops?

the corsair TX series or RMx series

suggestions cover the PSU series not the wattage. although a quality 500W or more will do you at stock speeds

I think I've solved it. I forgot to mention I also added an SSD to my build which would be taking more wattage. After unplugging one of the case fans (it wasn't spinning very fast at all) and unplugging the dvd drive the comp has since worked flawlessly. If I ever look to upgrade I'll definitely be getting a new PSU but as of now, it's perfect. Thanks for the help!
