Hi this pc was not a prebuilt it was mu uncles im not sure that exact model its a 400w evga psuBest GPU a certain CPU can handle will vary game to game and settings etc.
What is the make and model of your power supply? is this a prebuilt?
so a 1650 is the best option?Most GPUs are expensive these days due to assorted global factors/shortages, crypto currency miners, etc...
A GTX1650 is allegedly the current best seller, and most do not need any supplemental power.
