It has a x16 PCIE card so we have no real power supply upgrade easy to find so let's get with just enough video to play a dvd?
Links ONLY from this point on.

Looking to connect my c521 to my samsung hdtv. Need Dvi/hdmi access. Which video cards will fit the c521 since its a slim tower that will have dvi and/or hdmi? (if only dvi then fine because i'll get an adapter). Also, i've read that i only have 280 watts power supply. Any new card will need minimum 300 watts. Can the power supply be chaged on this computer to 400watts or 500 watts?
Thanks in advance..
