Motherboard & CPU Combo
This bundle pairs the ASUS PRIME B850-PLUS motherboard with the AMD Ryzen 9 9900X processor for Socket AM5. The combination targets enthusiasts building a high-performance desktop around the Zen 5 architecture and DDR5 memory.
DIY-Friendly Installation
A pre-mounted I/O shield simplifies motherboard placement in the chassis. Fan Xpert 2+ provides granular cooling control, while Aura Sync addressable Gen 2 headers let you coordinate RGB lighting without extra adapters.
Capacity & Headroom
The 12-core, 24-thread CPU reaches a 5.6 GHz max boost with 64 MB L3 cache and supports DDR5-5600. Storage headroom comes from one PCIe 5.0 x4 M.2 slot (up to 128 Gbps) plus two PCIe 4.0 x4 slots, while 2.5 Gb Ethernet handles wired networking.

Perguntas sobre este artigo
How do I verify the 12+2 phase VRM is delivering stable power to the Ryzen 9 9900X after build completion?
Enter the UEFI and monitor the CPU Vcore and VRM temperature readings under load; steady voltages and controlled thermals confirm the Digi+ VRM is operating as designed for the 12-core processor.
The combo lists a pre-mounted I/O shield — which other components must I purchase separately to finish the system?
You still need DDR5 memory modules, a CPU cooler compatible with AM5, storage drives for the three M.2 slots, a graphics card, a power supply, and a chassis.
The board offers one PCIe 5.0 x4 M.2 slot and two PCIe 4.0 x4 slots — which should I use for the primary OS drive?
Install the OS on the PCIe 5.0 x4 M.2 slot to utilise the full 128 Gbps bandwidth; reserve the two PCIe 4.0 x4 slots for secondary storage or games.
