Hey everyone! I recently built a PC using some used parts, and I'm using an older Be Quiet Pure Power 630W power supply with a Ryzen 7 2700X and RX 5700XT Gaming OC graphics card. Lately, I've been running into a problem: whenever I try to launch more demanding games like CS2 or PUBG, my screen goes black and my mouse and keyboard turn off. The case fans and CPU cooler still run, but I have to manually turn off the PC to get it to reboot. Interestingly, lighter games like GTA San Andreas don't trigger this issue. I'm starting to think the problem is with the power supply—maybe it can't provide enough power when the GPU demands it. What do you all think? Should I look into getting a new PSU?

Have you tried running a benchmark to see if the same issue occurs? That could help pinpoint whether it's really the PSU or something else. If you haven't, try running something like 3DMark to stress-test your GPU and see how the system reacts.
If you can replicate the issue with a benchmark, that’ll give you a clearer picture. If your PSU can't handle the load, then it might be time to invest in a new one, especially if you're gaming on more power-hungry titles.
It does sound like a power supply issue, especially since lighter games work fine. Consider getting a PSU with higher wattage and better efficiency if you end up replacing it. Safety first!
