hey olin, what are your cpu and gpu temperatures while playing?

I think it's your powersupply, can you try another game?

So far I try
Monster Hunter world, Apex, Dark souls 3, We were here too, Rainbow six.
Yesterday I play Apex my PC crash one time, even the "We were here" has crash several times.
But Interesting is, I try to play Dark souls again,and play it few time it didn't crash, run smoothly.
Weird.

thats because dark souls is not graphic intensive, im sure if you play gtav or the witcher 3 it crashes.
Most likely a psu issue, when the grpahics card draws too much power.

Monitor temperatures when it crashes.
BIOS and graphics drives up to date?
It might be your PSU

Is 650w not enough for RX480?

It's not the wattage that's a problem, it's the quality of the parts
