According to what I understand, there are no AM5 boards without a VRM that can't support the 9800X3D in stock. Unless you plan to upgrade to a more power-hungry chip like a Ryzen 9 later, the VRM setup on AM5 boards is mostly fine. They work well with Ryzen 5 and Ryzen 7 components. For now, you can purchase any AM5 board and expect full performance from the 9800X3D. Maybe Zen 6 will face higher power limits in the future, but currently it's still possible.
It should work well as a solid board for a 9800X3D in a SFF configuration. It seems to offer an actual 8-phase VRM design (no doublers) for the CPU. Compared to 10-phase versus 8-phase at 80A each, it probably won’t change much for the 9800X3D and 9950X, though that could vary.
