I have a HP P7-1154 computer with a built-in graphics card. I would like to add a better graphics card for gaming. I have a Nvidai GeForce 8400 GS graphics card I would like to plug into it. I am guessing I will need to add a stronger power supply to handle the card. What do I need and anything else?
You will need a 300 watt power supply minimum for that card. If you are planning on playing games like crysis or battlefield 3 ect ect... i suggest you go for a 9800GT or HD 4850. also depends on your budget.
