Question PC crashes while playing most games, have to replug the cable of the power supply

[DynamicProgram]

So basically, yesterday i got home, i finished with my setup (also got a new monitor which could be the issue but probably not), and my pc started crashing pretty often when playing some games, it crashed while playing counter strike global offensive, minecraft and probably some other games too(geometry dash doesent crash it for some reason). i checked my cpu and gpu temperatures, decreasing my ram temperature, but nothing seems to be effective and i am starting to think my psu is faulty or it doesent provide enough power so it all shuts down, any help is appreciated.


Processor AMD Ryzen 5 1600 Six-Core Processor 3.20 GHz
Installed RAM 16.0 GB
GPU is a gtx 1050 ti PALIT
my psu is a coolermaster mwe 500 230V
my motherboard is a b450m K II
250GB ssd
1TB HDD
