Questions about this item

What PCI Express generation and lane configuration does the board provide for graphics cards?

The board offers two PCIe 5.0 x16 slots that can run at x16 or split to x8/x8, x8/x4/x4 or x4/x4/x4/x4 depending on the installed CPU.

What case clearance and power connectors are required for the extended ATX board?

An extended ATX case is needed; the board uses ProCool II connectors fed by 24 plus 2 plus 2 power stages rated at 110A each.

How is the bundled Ryzen 9 9900X installed in the AM5 socket, and which step is often missed?

Lift the retention lever, align the triangle on the CPU with the socket marker, lower the lever fully, then attach the cooler — many builders forget to remove the protective plastic cover on the socket before seating the processor.
