Hey guys, my optiplex has everything i need for my gaming needs except graphics card. I'm on a very tight budget so I got an R7 260x for free from a friend. Problem is he didnt have the PCIe cable, thats easy enough though as I can order online for like $2, but it seem my computer has nowhere for the other end to plug in. Do i really have to drop $50 for a power source or is there something im missing. Thanks
