My PC randomly powers off when I combine heavier workloads, such as playing CS:GO while streaming or running Minecraft and League of Legends at the same time. I have a Ryzen 5 7600X, Radeon RX 960 XT, Gigabyte B650 AORUS ELITE AX motherboard, and Corsair HX750 80+ Platinum power supply. CS:GO runs normally when I play without streaming, but after a few rounds during a combined workload the system suddenly shuts off and requires pressing the power button to restart. I already replaced the graphics card and PCIe power cable, but the problem continued. An OCCT Power test ran for 10 minutes without causing a shutdown. What should I check next, and could the PSU still be the cause?

Temporarily disable EXPO in the BIOS and run the same games and streaming setup again. Unstable memory overclocking can appear fine in many tests but fail only under certain combinations of CPU, GPU, and RAM load. If the shutdowns stop with EXPO disabled, you can troubleshoot the memory settings from there.
A sudden power-off usually points toward overheating, unstable settings, or a power-delivery problem rather than a normal software crash. Check CPU and GPU temperatures under the exact workload that causes the shutdown, and look in the BIOS and Windows event logs for hardware or power-related warnings. The fact that an OCCT test passed doesn't completely rule out a problem, since different workloads can stress the system in different ways.
Make sure the motherboard BIOS is fully up to date. After updating it, load the factory defaults and test again before re-enabling performance settings. Older BIOS versions can have stability problems with newer Ryzen systems, especially when memory or boost settings are enabled.
My BIOS is actually still from 2022, so I'm updating it now. I'll test the system afterward and see whether that resolves the shutdowns.
I checked the Windows event log, but unfortunately nothing useful appeared there.
