I have my HP 8200 Elite SFF, AND I want to add a dedicated graphic card into it. I want to use it to play some games (not resource-hungry games, I play games like The Sims 4, Minecraft, you know, simple games). I was looking for graphic cards and found the GT 710. It's cheap and looks nice, but the power supply must be 300W minumum, when mine is 240. I have read many posts that say the card doesnt use more than 50W and it works perfect, some say it won't work and will fry up everything. I was looking power supplies for my PC and there are not upgrades apparently. So I wanted to know if I can use that GPU with my PSU, or if I need to get another PSU and which I should get. Right now the PC has 8GB RAM, a 250GB HDD, an i5-2400 processor, and Intel HD Graphics 2000 integrated graphics (and the 240 PSU). I usually connect 2-4 things to the USB port. Hope this info is useful.
