My current PC has a Ryzen 5 4500, 16GB of RAM, an RTX 3060 12GB, an MSI A520 motherboard, a 500W FSP H2-500 HEXA+ dual-rail power supply, and a 1TB SSD plus a hard drive. I'm considering upgrading the motherboard and processor to a B550 MSI Pro-VDH and a Ryzen 7 5700X. Would this combination cause any problems, particularly with the power supply or motherboard VRMs? Would the CPU upgrade noticeably reduce a bottleneck with the RTX 3060? I mainly use the system for 2K video editing and gaming, so I'd also appreciate suggestions for better-value upgrades.

A 500W power supply should be enough for a Ryzen 7 5700X and RTX 3060 as long as it’s healthy and has the proper PCIe power connector. However, it’s not a particularly high-end unit, so replacing it with a good-quality 550W–650W model would improve reliability if the budget allows. You probably don’t need to replace the motherboard just to run the 5700X; the A520 board may support it after a BIOS update, though its VRM cooling and BIOS support should be checked first.
Before buying parts, monitor CPU usage, GPU usage, temperatures, RAM usage, and storage activity while gaming and editing. If the GPU is consistently near full usage, the graphics card is the limit and a CPU upgrade won’t increase performance much. If the CPU is maxed out while GPU usage stays low, the 5700X could help, although seeing only 50–60% total CPU usage does not rule out a CPU bottleneck because one or two individual cores may be fully loaded.
Run the same checks during video exports too. Editing performance can depend on the software, codec, storage speed, and whether the program uses the CPU, GPU, or hardware encoding.
The Ryzen 5 4500 is a relatively weak gaming CPU, so moving to a 5700X would improve minimum frame rates and help with multitasking and video editing. That said, the RTX 3060 will still be the main limit in many games, so don’t expect a huge average-FPS increase unless the current CPU is actually holding it back. If you stay on the AM4 platform, consider the 5700X while keeping the current board if BIOS support and temperatures are acceptable. Increasing RAM to 32GB may also be a more useful upgrade for 2K editing and modern games.
The VRMs may be less comfortable with sustained heavy workloads, especially during long editing sessions, but a stock 5700X is generally not an extreme load. Check the exact board model and update the BIOS before swapping CPUs.
