So i decided to get a new graphics card. Which then turned into me also getting a PSU. I've never really messed with a computer like this before. I have a micro atx board. I opened up my case. Moved the optical drive so i could see where my PSU connects. I only saw the big 20 pin connector. No 4 pin. Can a PSU with a 20+4 pin work with a motherboard without the 4 pin? Im probably wrong and just didnt see it. But i want to make sure before i spend the money.
