I recently acquired a Dell MT3804 Motherboard that I wish to upgrade to. I've been trying to calculate how much power I need to run it with everything I have, but I can't figure it out because I can't find what type of motherboard the MT3804 is (ATX, E-ATX, etc etc?). I currently have a 750 watt power supply (RM750 Gold). Does anybody know either what type of motherboard it is or if I have a strong enough power supply? If not, how much do I need?

Specs for the computer:
CPU: i9-10900X
GPU: Radeon Pro W5700
RAM: 1 stick 32GB DDR4
Storage: 1tb NVME SATA & 2tb HDD Hard Drive
