The VRM may reduce its output to prevent overheating.
Hello, your current TUF B450M PRO gaming card supports the R7 5800X3D setup well. Since you don’t need PCIe gen 4, upgrading the motherboard isn’t the priority here. Check if your existing board can handle the thermal demands of the new GPU without throttling. If it’s likely to struggle, consider a more affordable budget motherboard that still meets your needs. Your R5 3600 with CX750 provides enough headroom for heavier workloads.
The cooling on the VRMs looks quite good, which means you should be fine. You’ll notice it more clearly once it’s installed, and if power isn’t stable, consider upgrading to a better B550 board—though it might be a bit of work.
Absolutely, having the B450M-Pro S would be amazing. Don't compromise too much—it'll pay back soon.
