Pc shutting down when gaming

[Gekkon]

CPU: AMD Ryzen 7 3800X
RAM: G.Skill trident z neo 4x8GB 3600Mhz

CPU cooler: aorus x 240 waterforce
Mobo: x570 aorus master
GPU: rtx 3080 gigabyte vision OC

PSU: corsair RM750

When playing high resource games like apex legends halfway my pc just shuts down but when playing valorant for long hours it works fine. I do not have an extra PSU so want to make sure if its really the PSU problem before purchasing a new one. All drivers and bios is updated to the latest version. Anyone able to help?

I would recommend running a monitoring software like HWinfo64 to see what happens when the system shuts off. 750w psu is likely the issue, 3080 can have transient power spikes that will trip OCP/OPP on 750W PSU

Same with what BiotechBen was saying. Potentially between the 3800X and the 3080 OC version you're tripping the OCP/OPP. If you have a second monitor pull up HWinfo64 and watch whats going on between power and heat. Depending on your case you might have temps going too high as well. So just keep an eye on both.

Kit of 4 or 2 kits of 2?

Test with 2 sticks in A2 and B2.
