300w eh. You might be able to get away with an GPU upgrade. How will need to confirm the amps on your PSU
There should be a listing for 12v and a number under that says 20a for example. What is this number?
unfortunately i wont be able to see that lol. that is on the back and for me to look at that, i would have to unhook everything and pull out my entertainment center. my setup is kinda crammed all together atm
