ok so i have a Geforece gt 730 witch is the 2048 mb ddr3 version from pny i know its a low end card but its all i can afford at the moment. so with that being said id like to overclock it but i have some concerns i have read that some people have had success with doing so with this card; but i worry my psu cant handle it. its a max 300 w psu and my new GPU draws a very low 23 watts. i do keep my machine clean and well ventilated but it is older and so is my psu so would i be safe doing so or am i putting my psu at to much of a risk. if any other information is needed just let me know il be standing by thank you!
