Question Pc restarts when running high end games

[Noeyo]

So i built this pc a month ago specs are below. I got my first problems when I tried to play rust and then new world. Basically the pc restarts after about 30seconds to 1 minute of play time. I thought it was the drivers so updated them and it still did it then I thought maybe my graphics card was faulty so I ran a benchmark and everything was fine. I am quite lost and I don't know what to do. Also temps are fine during graphics card benchmark max temp was 72° and my Cpu temps during cinebench is 55-60°.

Specs:

AMD ryzen 5 5600x
Asus rog strix B550-F gaming wifi
Asus Rtx 3060 12gb
Asus rog strix 750w atx power supply
16gb DDR4 3600Mhz
1 tb western digital m.2
Corsair H100x aio cooler

Only 3 things I can think of

1: Ram problem
2: PSU not supplying enough power.
3: PSU overheating

Try running memtest86 for a few hours and see if it catches any errors

So I ran memtest86 today for about 3 hours and it didn't catch a single error I am now thinking of swapping power supplies with my other pc but it's only a 500w unit so I don't know if that will be enough ?
