My dad freaked out beacuse when I told him the video card I was gettting needed 300w and our power supply only has 350ish. A) What will happen if the video card won't get enough power? B) Could doing this damage any part of the computer? C) How many watts will I need for it to bet safe? O ya this stuff: 1 CD/DVD drive 1 Floppy drive 2 Hard drives (1 internal, 1 external) I need to know this kind of fast because the time on ebay only last for a few more days.
