The load on the video card drops

In general, when my processor starts to work at 70-80%, the voltage on the video card drops, the load actually drops and the frames in the game fall, I'm trying to understand what the problem is mb someone came across, thought that the problem was in the power supply, took a Corsair CV450 from a friend 80+ Bronze everything is exactly the same

CPU: Ryzen 1600af 3600mhz
GPU: MSI GeForce GTX 1650 SUPER VENTUS XS OC
Mother: MSI A320M-A PRO (maybe it's in her xs)
RAM: Crusial Balistix 3000mhz 2x8
PSU: Chieftec ATX 600W iArena
SSD: 240gb goodram

I have already tried everything in which there could be obvious reasons from changing Windows to changing bp and RAM, I don't know what else could be, in the hope that they can help me here


this is not only in cyberpunk, but also in many other games, although when I watch a video with my pc configuration, everything works stably for people
