3 Things to Know About the ASUS ROG STRIX B650-A’s PCIe Slots

Both PCIe x16 slots run at PCIe 4.0 The primary slot runs at x16 from the CPU, and the second runs at x4 through the chipset. There are no PCIe 5.0 slots on this board.

This is an unusual omission for a premium AM5 board Most ROG STRIX boards include PCIe 5.0 support. Skipping it on a B650 board limits future-proofing for next-gen GPUs or SSDs.

PCIe 4.0 is still fast enough for current GPUs You won’t notice a performance difference with today’s graphics cards. But if you plan to upgrade to future hardware that uses Gen 5 bandwidth, this board won’t support it.
