I'm trying to upgrade from on board to a graphics card. I have a dell inspiron 660s. It's a sff so the card has to be sff as well. I'd like to get away with useing the power supply that's already in it. It's a 220 if I'm not mistaken. I've seen older post on here about this but there several years old. I'm trying to find out what my options are in 2017 for a good card that will use my power supply that I already have and that isn't going to break the bank. 100/120 seems reasonable for a card. If anyone has any suggestions I'm all ears. Thanks in advance. And if I can provided anymore info plz let me know what u would need.
