Yes, the ASRock B550 Pro4 can boot headless (without a GPU) when paired with a compatible AMD Ryzen processor, such as the Ryzen 3600, as confirmed by a user on Linus Tech Tips with BIOS version 2.40. However, some ASRock motherboards may require a GPU during POST, as noted in a discussion about a different ASRock model (X470 Taichi Ultimate), where the system failed to boot without a graphics card.
Since the B550 Pro4 supports headless operation in at least some configurations (e.g., with a Ryzen 3600), it should work for headless server setups, but success may depend on the specific CPU and BIOS version. For example, CPUs without integrated graphics (like most Ryzen processors) may still boot headless on this board, but you should verify the BIOS settings, such as disabling any GPU-dependent checks or enabling onboard LAN for remote access.
If you're planning a headless setup, ensure your BIOS is updated, and check for any settings related to boot or POST requirements in the manual. If you encounter issues, a low-cost GPU might be a workaround, though it’s often unnecessary for this board based on user reports.
