First off , I be familiar with computer hardware but be in no mean a tech . I order this graphic card with a  Corsair Enthusiast Series 850-Watt 80 plus bronze certified power supply compatible with Intel Core i3 , i5 , i7 and AMD platform - cmpsu-850txv2  while there be not many instruction with the card on how to install I watch enough `` how-to '' video to feel semi comfortable open the computer case and replace the card . as I progress I find out that installation of a pcus express card be a breeze and I have no need to be apprehensive in the first place . Make sure to plug in everything include 2 power cable ! turn on the computer and install the driver with the provide cd and wallum ! I be able to play all the game I want on the highest graphic setting -lrb- shogun 2 and swtor -rrb- . I highly recommend this product ! Update : Make sure to pay attention to the `` Product Dimensions : 12.5 x 3.5 x 6.5 inch . '' the card be very large ! install in my boss computer and have to move a hard drive . however , all go well .
