Hey there, I hope I'm posting this in the right place but I was looking at getting a refurbished Dell Precision T3400 off of amazon and was looking to upgrade the graphics card to a EVGA GeForce GT 740 Superclocked SS 4GB but looking it over I don't know if I would need to get a new power supply as well and if I do wouldn't know which one I would need. Here is some of the information I have for the stuff as well as what dell says about the power.
If someone could help me that would be much appreciated
