https://www.coolermaster.com/catalog/power-supplies/mwe-series/mwe-550-white-230v-v2/#image-Item9 i have this PSU with 2ssd and 1 hdd16gb ramWith no specific model, can't really say.
80+ spec is pretty easy to meet these days, there are better power supplies for not a lot more.
200W GPU, 65W CPU, probably looking at a good 550W supply. How much do you have to spend?
That's the bottom quality recommanded to use with a 3060Ti.
