The ROG STRIX B650E-I GAMING WIFI motherboard supports Ryzen 7000 and 8000 Series processors, but does not directly specify support for the Ryzen 7 9800X3D. However, the Ryzen 7 9800X3D is part of the 7000 Series, so it may be compatible. To confirm compatibility, I recommend checking the list of supported processors on the manufacturer's official website.
Yes, the "ROG STRIX B650E-I GAMING WIFI" motherboard supports the AMD Ryzen 7 9800X3D. This processor belongs to the Ryzen 7000 series, which is supported by this motherboard as it uses the AMD Socket AM5 and the AMD B650 chipset.
The motherboard has two m.2 slots
1 x M.2 2280 (PCIe 5.0 x4)
1 x M.2 2280 (PCIe 4.0 x4)
This should not be a problem for the FireCuda SSD from Seagate.
