Im thinking of getting a used psu (Seasonic SS520GB) I can get it for $32 Delivered at my door step. I was wondering if it is a good psu unit and will it last me or not? I plan on using i7 4790 + GTX 1660 Super/ Entry level RTX 3000 series card + 1HDD + 1SSD
It is 520watts as the seller said. Should i get it? Is it reliable?
The PSU is the most important part of a computer. PSU selection comes before GPU selection. If you can spend the money to upgrade to a new RTX 3000 series card you can get a better PSU than a used, 10 year old design. Get a good power supply first and then decide what GPU will fit your build and budget.
