Our take on the ASUS Prime B650M-R Motherboard AMD Ryzen 9 9900X CPU Combo

A bundle pairing ASUS's Prime B650M-R micro-ATX board with AMD's Ryzen 9 9900X, a 12-core, 24-thread Zen 5 desktop CPU. The board covers the essentials: PCIe 4.0, two M.2 slots, Realtek 2.5Gb Ethernet, front USB-C at 5Gbps, VRM and chipset heatsinks, and Aura Sync RGB headers. It suits builders who want strong multi-core CPU performance without paying for a premium board's extras. Against pricier B650 and X670 boards it gives up PCIe 5.0, extra M.2 slots and heavier power delivery, which matters little for most gaming and general use but limits overclocking headroom and fast storage expansion.

Questions and answers

Is the Ryzen 9 9900X good for gaming?
Yes. Its 12 Zen 5 cores keep up in games, and it is strongest where games also stream or run background work. A cheaper 8-core chip often matches it in pure gaming for less.
Do I need a BIOS update for the 9900X on this board?
The 9900X is a Socket AM5 chip, and B650 boards support Ryzen 9000 series with a current BIOS. Older stock may ship with an earlier BIOS, so check the revision or plan to update before first boot.
Can I overclock the 9900X on the Prime B650M-R?
The board supports CPU and memory tuning, but its power delivery is modest for a 12-core chip. Expect limited headroom compared with a premium B650 or X670 board; Precision Boost usually does the work for you.
Does it have Wi-Fi?
No. The board has Realtek 2.5Gb Ethernet only, so you need a wired connection or a separate Wi-Fi card or USB adapter.
What comes in the box?
The ASUS Prime B650M-R motherboard and the AMD Ryzen 9 9900X CPU. A cooler is not included with the 9900X, so plan for an AM5-compatible cooler.
How many M.2 drives can I install?
Two M.2 slots, both PCIe 4.0. That covers a boot drive plus a second fast drive, but not the PCIe 5.0 storage found on pricier boards.
Where is the ASUS Prime B650M-R Motherboard AMD Ryzen 9 9900X CPU Combo cheapest?
At Newegg, for $759.99, as of our latest check.
