So I have been looking at a graphics card for my pc (Dell Inspiron 3847) and it has a 300 Watt power supply. The card I am looking at is the Nvidia Geforce GTX 750 graphics card which on the Nvidia site says it is compatible with a 300 Watt power supply and on the newegg site says 400 watt. Can I run this card on the power supply I got or do I need a new one? I'm not sure if I were to get a new one if it would work with a dell and my budget is a bit of an issue.
