I upgraded a old system with a 500 watt Cougar VTE Bronze power supply with a Rtx 2060 and Ryzen 5 3600 with PBO enabled. According to this https://www.techpowerup.com/review/amd-ryzen-5-3600/18.html under a full load the wattage is still rated under 400 watts even with a RTX 2080 Ti. Yet, I have seen posts floating around about how overclocking and such could overload a PSU and how I should get at least a 600 watt PSU, but I don't want to spend even more on this build, should I trust these claims or am I just paranoid?
