Question Help - AMD Ryzen 7 9800x3d & GTX 5090 pc constantly shutting off

[goot]

Have a brand new PC with a AMD Ryzen 7 9800x3d and GTX 5090 card and 1500W PSU

When gaming after about 10 - 20 mins, the computer randomly just suddenly shuts off

as if someone just disconnected power to the computer

I don't get any error logs or anything in Event Viewer

Is this a faulty PSU ? Faulty GPU?

GPU and CPU temps are fine

I have very good cooling in the PC

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:

include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

A PC will shut off due to two reasons. 1| An overheating issue. 2| Your PSU is incapable of power your entire system when taxed.

If you are saying that you have good temps just because you have good cooling....
Use msi afterburner and actually look at the temps while gaming.
