Question Pc shuts off when gaming specific games

[That Dutch guy]

first thing’s first:
B450i aorus pro wifi
Ryzen 5 1600(am planning to upgrade)
Gigabyte aorus gtx 1080ti Xtreme edition
Corsair vengeance lpx 2x16gb 3600mhz
Rog strix 750w
H710(with all fans)

The problem
When I play games like satisfactory after 10-30min, the pc shuts off and the fans keep spinning. And the psu indicator on the gpu start flashing
And if I manually restart the pc everything is fine

I bought 3 extra hi performance fans bc I thought it was an overheating issue but when it shuts of the last frame said the gpu was only at 60 C

Now I don’t know what to do

If PSU can't draw enough power, it will shutdown or restart your PC. Means you'll need a new PSU.

Yea I get that but it’s quite a new unit and it also is 750w which is overkill. So I don’t think it draws to much power.
