[SOLVED] Newly built PC in July

Jul 6, 2019
Hey hows it goin guys?

So I built my pc in July i used pc part picker like everyone else to choose the components. When i decided to built it everything went well and it works. I recently went back to pc part picker to see if the gpu i want to upgrade too would be compatible (I’m a newbie btw) and then i see this message for my current build: The MSI B450 GAMING PRO CARBON AC ATX AM4 Motherboard has an additional 4-pin ATX power connector but the Cooler Master MWE Gold 750 W 80+ Gold Certified Fully Modular ATX Power Supply does not. This connector is used to supply additional 12V current to the motherboard. While the system will likely still run without it, higher current demands such as extreme overclocking or large video card current draws may require it.
What does this mean?
