A bundle of ASUS's Prime B850M-A micro-ATX board and AMD's Ryzen 9 9900X, a 12-core, 24-thread Zen 5 desktop CPU. The board covers the essentials for a compact build: PCIe 5.0, three M.2 slots and 2.5Gb Ethernet, with no Wi-Fi included. The 9900X is one of the strongest all-round AM5 chips for gaming and heavy multitasking, though it runs warm and wants a good cooler. Buyers who need lots of PCIe cards or onboard wireless should look at a full ATX or Wi-Fi-equipped board instead.

The Ryzen 9 9900X is well received for its 12-core performance in gaming and heavy multitasking, with reviewers noting it trails the X3D chips in some games. The Prime B850M-A is seen as a solid, no-frills micro-ATX board whose lack of Wi-Fi and modest power delivery are the main gripes.
This bundle pairs the ASUS Prime B850M-A motherboard with the AMD Ryzen 9 9900X processor. The board uses the AMD B850 chipset and an AM5 socket, in a micro-ATX form factor.
The board is PCIe 5.0 ready and has three M.2 slots for storage. Networking is handled by Realtek 2.5Gb Ethernet.
