Question about ASUS TUF GAMING B650-PLUS WIFI

Hi guys, my new power supply only has a 24pin connector, which I plugged into the ATX behind the power banks. I have nothing left for the power connector next to the CPU. The board only has limited power, it doesn't flash or do anything else. Shouldn't the 24pin be enough? Or does the CPU need extra power, i.e. me, another power supply? Thank you very much. lynx
