Ok I have a 500 watt psu and I am at the limit. Sometimes I have to open the computer case and unplug video card then plug it back in for it to work. But I saw a while back a internal psu like thing that you put in the cd drive spots and it provides additional wattage for the computer, for like video cards and stuff like that. I can't find anything that is like that online. Idk what it's called. But I want to know if anyone has heard of this or Did I just see the thing wrong.
