Should I upgrade my PSU?

Hi all! I’ve got a system here with a 750W PSU, RTX 2060, and Ryzen 7 3800X. I also have two sticks of 16GB RAM (DDR4), 1 SSD, 1 HD (@ 5400 RPM), all on a Mini-ITX board. I’m looking to upgrade to an RX 6800 XT and am slightly worried my PSU won’t be enough. I also have five fans and use several peripherals, like an audio mixer, stream deck, and elgato prompter. Just curious to see your thoughts on if I should upgrade my PSU or it will be enough. Thanks so much!
