Pc shuts down after running game randomly

[DD-king]

My pc suddenly shuts down when I play valorant or any other game randomly.

I performed all the benchmarks like heven benchmark for GPU about 2-3 times on repeat and the Max temp. on gpu was 85.

I don't understand what's the issue is.

When the pc shuts down and then I try to power it again all the case fans and cpu fans spin but there is no display output and the GPU fans do not spin indicating power to GPU. Then after some time it starts and everything is working great until it shuts down again.

 

My specs

Ryzen 5 5600x( with deepcool ak400)

Gigabyte B550m wifi

Sapphire pulse Rx 6600 (used)

WD SSD sn570

Psu gigabyte p650b

Since you bought it used, i dont know how old it is. But the thermal paste may have failed

How long have you had the RX6600?   If you bought it used, it may have had issues and that's why it was being sold.  Something to check into.

 

What case do you have?  How's the airflow?

 

Agreed with below... possible PSU tripping, which may be due to a faulty GPU.

Honestly sounds like it could be a PSU issue, but I may be wrong.

To check id swap the PSU to see, if it works alright then you'll know.

I have sent me psu for rma they are doing a burn-in test.

I have had that GPU for 3 weeks now.

They had it for almost a year and they didn't used it much and I performed stress tests on the GPU and it was working fine before I bought it.

Air flow is quite good for the case I have 2 exhausts and 4 intake. Thermals are around 85 for GPU.

It's around 1 year old. I don't know how to check if the thermal paste is failing cus it didn't shut down during the stress test and did shut down where I played any game at random. 

I played valorant for 1 hour and then I played warzone for a bit nothing was worry then it suddenly shut down.
