hey guys im from brazil, and im buying a new PSU, my current one is 7 years old and only 500W, and im upgrading to a RTX3080 and using psu calculator i need about 605W, but searching for PSU prices i found a XPG core reactor 650W for (630 reais - 120 dolars) but the 850W version is (650 reais - 126 dolars) is there any benefit in buying the 850W version the price is really really good and i only need the 650W version but i know basically nothing about PSU so is it better to buy the 850W version?
