I've been using my PC for quite some time and recently upgraded the power supply (PSU) and the graphics card to an Asus Dual OC Radeon RX 7700XT. However, I noticed that my old Ryzen 5 1400 CPU was bottlenecking the performance, so I decided to upgrade to a Ryzen 9 5950X along with a new cooler. Since then, I've been having some issues where all peripherals disconnect at random times, and I'm starting to think it might be due to a mismatch with my motherboard. I'm currently using an ASRock AB350M Pro4 micro ATX AM4 board, which was part of my original build. My questions are: 1) Could these issues be due to a CPU/motherboard mismatch, even though PCPartPicker didn't list any errors aside from the BIOS version, which I did update? 2) What problems can arise from using an old motherboard with such a powerful new CPU? I believe I've already updated my drivers, but if that's a potential issue, feel free to let me know!

The age of the motherboard itself doesn't necessarily mean there will be major issues when pairing it with a high-end CPU like yours. The main thing to check is the connectors—try different ones just in case. It's unlikely a mismatch is the problem as long as the motherboard supports the new CPU, which it does. Just make sure everything is connected properly.
Just to share my experience, I've had motherboards last over a decade without major issues. Age isn't always the problem! But yeah, the power delivery on older boards can struggle with newer, more demanding CPUs, so that's definitely something to consider.
It's possible the motherboard is a bit worn out, or the VRMs (Voltage Regulator Modules) aren’t strong enough to handle the new CPU. This can lead to instability and disconnections with peripherals.
Have you checked your BIOS version? You should be running P7.20 for your CPU. Sometimes, not all settings update automatically, and having older settings might lead to issues. Also, what chipset driver version are you using?
From what I found, the chipset software version is 7.06.02.123, but it might be worth double-checking that it aligns with your hardware's needs.
Also, are you sure your PSU is functioning well? Since the issue started after the CPU upgrade, you might want to investigate whether it's providing enough power—sometimes testing it without the new CPU can help narrow it down.
I feel about 90% confident the PSU is fine; it had been working well with the previous setup before the CPU swap. It's a gold-rated PSU.
Honestly, this could stem from various issues—anything from a memory overclock to the motherboard’s capability itself, or even the PSU. Did you tweak any settings recently? I've personally encountered similar issues when I pushed my Ryzen too hard.
I updated the BIOS to 7.20 before switching CPUs, but didn't tweak any settings afterward. Right now, my PC is running a memory test because it started beeping on startup, indicating a memory issue. I'm not sure about the driver versions at the moment, though I did use the AMD tool to grab the right ones.
