I recently bought a power supply, the thermaltake smart series smart 700w 80+ plus rated power supply, for my build. But soon realized that the mother board had a additional 4 pin atx conector while the power supply does not. i looked it up and it said the system will probably still run expect if a higher current demand requires it like overclocking or a large video card. I am not planning to over clock anything but does a rtx 2070 super founders edition count as a large video card? The cpu I have in the build is a ryzen 7 3800x if that helps.
