System failure occurs when processing demands exceed capacity.

It isn't the power source, I verified. My system runs on an ASROCK B450 Steel Legend board with two monitors—1440p at 144Hz and a 1080p at 75Hz. It uses an AMD Ryzen 7 5800X and Radeon RX 7600 XT from XFX, paired with 32 GiB of DDR4 RAM. I'm using Void Linux, but I've faced problems with Fedora and Ubuntu across different kernel versions. Experiences vary: GNOME, KDE, Hyprland, and most recently Sway all have issues. Under heavy load, the display abruptly stops, audio halts, and the side monitor briefly flashes green—possibly due to a card-to-HDMI interface fault. My suspicion is a mesa crash, maybe from thermal stress altering contact points. I'm not certain of the exact cause, but it's unlikely to be the power supply. The new 1300W seasonic power unit replaced my old 750W unit and didn't resolve the problem.
The voltage rails indicate deviations from the expected levels. This often stems from failing to meet current or power requirements rather than insufficient current or wattage. As a result, VRMs must compensate more, which can lead to increased stress and eventual degradation.
It occurs once the PC starts up for just a short time. Medium performance lasts several days, yet when I raise the FPS in a game it freezes within about ten minutes.
Well, actually, that's not the case. You're missing the point—what you really need to understand is that the updated PSU isn't the issue. It's likely the limited budget GPU. Try using just one monitor and check if the problem persists.
I'm setting up Windows on another drive tonight and attempting to recreate the setup. If successful, I'll run HWinfo64. If not, I suspect the problem lies with Mesa. I still have a reliable power supply that has served me well for years. I changed it recently, assuming it was the cause, but even the high-quality seasonic unit from the Ebay refurbishing program didn't resolve the issue. It seems unlikely both power supplies are faulty, given their performance in other systems. The GPU itself isn't a low-end model—it's an XT card, which is considered a mid-range build. XFX is highly regarded among AMD GPU manufacturers, comparable to Power Color. Of course, specs alone don't tell the whole story. I plan to test it with one monitor as you recommended.
