Combo for AM5 builders

The bundle pairs an ASUS B650E MAX GAMING WIFI motherboard with a Ryzen 9 9900X processor. The 12-core, 24-thread CPU runs on the AM5 socket and reaches a 5.6 GHz max boost. The board delivers an 8+2+1 phase power design on a 6-layer PCB with alloy chokes and durable capacitors. It targets enthusiasts building high-performance desktops for gaming and AI workloads.

DDR5 memory and PCIe 5.0 expansion

Four 288-pin slots support dual-channel DDR5 up to 192 GB at 8000+ MT/s when overclocked. A PCIe 5.0 x16 slot and a PCIe 5.0 M.2 2280 slot connect directly to the CPU for graphics and storage. A second M.2 2280 slot runs at PCIe 4.0 x4 from the chipset. Four SATA 6Gb/s ports provide additional drive bays. Rear I/O includes USB 10Gbps Type-A and Type-C ports plus front-panel USB 5Gbps Type-C support.

Sustained load cooling and network stability

VRM heatsinks, M.2 heatsinks and a PCH heatsink work with hybrid fan headers and Fan Xpert 2+ to manage thermals during extended sessions. Realtek 2.5Gb Ethernet and Wi-Fi 6E with Bluetooth 5.3 maintain low-latency connectivity. Realtek 7.1 surround audio with shielding supports 24-bit/192 kHz playback. BIOS FlashBack, Q-Antenna and Q-LED Core simplify troubleshooting without a full reboot cycle.

Questions about this item

Will the Ryzen 9 9900X run at its 5.6 GHz boost without a separate cooler?

The processor is unlocked for overclocking and reaches 5.6 GHz max boost, but no cooler is included in the box. You must supply a compatible AM5 cooler rated for the CPU's thermal output to achieve those speeds.

Can I install four DDR5 modules to reach the 192 GB limit?

Yes. The board has four 288-pin DDR5 slots supporting up to 192 GB total in dual-channel mode. Populate all four slots with matching kits for best stability at high capacities.

Which M.2 slot should I use for a PCIe 5.0 drive?

Use the M.2_1 slot (Key M, type 2280). It is wired for PCIe 5.0 x4 when a Ryzen 9000 or 7000 series processor is installed, giving the full 5.0 bandwidth to a compatible drive.
