Why Does My GPU Power Consumption Drop When Stressing Both CPU and GPU?

Asked By CuriousCoder42 On

Hey everyone! I recently upgraded to an Arc A750 from my old RX 580, primarily for work since most of my gaming is on the PS5. During a stress test, I noticed something weird: when I push both the CPU (Ryzen 3600) and the A750, the system crashes. The curious part is that the GPU's power consumption fluctuates and ends up dropping to about 5 to 6 watts, with usage dropping to 0%. I tried the same test with the RX 580 and saw similar behavior—the power consumption drops significantly, but it just stutters instead of crashing. My power supply is an old Cooler Master 650W. Do you think the PSU could be causing these issues, or is there something else going on?

Your GPU’s drop in usage likely happens because your CPU is getting overloaded and can’t send enough data to the GPU, causing it to throttle down. It’s probably not a PSU problem since drivers for the Arc GPU can be quite finicky with the combined load. If it works well with gaming and Furmark on its own, I’d say you’re still good overall.

I’d lean towards the PSU being the problem. Even though it’s rated at 650W, if the PSU is old (especially a Cooler Master, which has had some lower-quality models), it may not supply stable power anymore. It’s fine under single loads, but combined loads might spike the power draw too high for it to handle, leading to crashes. The A750 is more sensitive than the RX 580, hence why it crashes while the other just stutters. Consider upgrading to a better quality PSU!
