I bought an acer ax3200 u3600a desktop about a year ago and I want to upgrade my graphics card from the integrated geforce 8200. I am limited by the small form factor - I have one open pci e x16 slot (must be low profile card) and a 220w power supply that can do 16A at 12V. Does anyone have any suggestions for a card that will meet these specs? I have been looking at some 8400 GS's on newegg but I'm not sure if they'll work. Also, if I end up having to upgrade my PSU, will I need some sort of smaller-than-standard size PSU?

Thanks, I'm relatively new to modding PC's.
