Not sure. How do I check it?
If its not in your system documentation, you may need to open the case and look at the label on the power supply unit. When you open the case, take common electrostatic dishcarge precautions. If you are unsure about looking inside the case, it is easy and you can look at this site with instructions about installing a video card for simple instructions on going inside your case.http://www.upgradevideocards.com/install.html
