My computor is run on 300W..I want to add a video card which requires 350W..?

Could I run this video card or how can I change to 350W.My computor is run on 300W..I want to add a video card which requires 350W..?
buy a power supply and switch it out. it's simple. it takes a screw driver and about 5 minutes of your time. before you go swapping out any power supply unplug it.My computor is run on 300W..I want to add a video card which requires 350W..?
U still can run the video card, But it will soon blow off. try to get a video card that is less than 300 w
