rick30062001 :
hello thanks but my pc only has a 300 waw power supply does that make a difference ive never put a vidio card in before do they snap in just like ram does tthanks again rick hill
Yes, they do "snap-in" like the RAM. Please check the power leads coming out of your PSU - if they are all plugged-into a component, you will not be able to power a new GPU. If you have two unconnected MOLEX (flat 4-pin) connectors, you may be able to use the pigtail (the 2x6 power lead that attaches to one or two MOLEX power leads) that ships with the GPUs.
Please be very careful in selecting a GPU, make sure that the card's specs. indicate it will run on your 300W PSU.
