I just recently purchased a PowerColor AMD Radeon HD 7850 graphics card (which didn't come with a power adapter cable) amp; needing to know what the power adapter cable looks like. If anyone could possibly send me a link with a picture, that would help out a lot.
I think your power supply should already have one. If not not I suggest you look at PC Part Picker too find a good one that will work. Don't worry it will auto filter good ones for you. I can't help you if the graphics card doesn't have a female plug.
I have never seen one in my life! But have you researched it on google?
