Combo for AM5 builders

This bundle pairs an MSI MPG B850 EDGE TI WIFI motherboard with an AMD Ryzen 9 9900X processor. The board supports Ryzen 7000, 8000 and 9000 series CPUs on the AM5 socket. The included 12-core, 24-thread chip reaches a 5.6 GHz max boost and provides 64 MB L3 cache. It targets enthusiasts who want a ready-matched platform for high-end workloads.

DDR5 and PCIe 5.0 limits

Four 288-pin slots accept DDR5 up to 8400 MT/s when overclocked, while the CPU itself is rated for DDR5-5600. One PCIe 5.0 x16 slot and one PCIe 4.0 x16 slot handle graphics and add-in cards, plus a PCIe 3.0 x1 slot for legacy devices. Four SATA 6Gb/s ports and quadruple M.2 connectors cover storage. Networking uses 5Gbps LAN, Wi-Fi 7 with 320 MHz channels and Bluetooth 5.4.

80A SPS VRM decides fit

The board’s 80A Smart Power Stage VRM and extended PWM heatsink are designed to sustain the 9900X at full speed. If your build demands stable power delivery for prolonged all-core loads, this VRM specification is the key figure to verify. The ATX form factor fits standard chassis, and 7.1-channel Audio Boost 5 handles output.

Questions about this item

Which CPU is included in this combo and what are its core specifications?

The bundle includes an AMD Ryzen 9 9900X with 12 cores, 24 threads, a 5.6 GHz max boost clock, 64 MB L3 cache, and 12 MB L2 cache based on Zen 5 architecture.

What does the DDR5 8400+ MT/s overclocking figure mean for actual memory performance?

The board supports memory overclocking up to 8400+ MT/s with DDR5 modules, while the Ryzen 9 9900X officially supports DDR5-5600; higher speeds require manual tuning and compatible kits.

How fast is the Wi-Fi 7 connection and what bandwidth does the 320 MHz channel provide?

Wi-Fi 7 uses a 320 MHz channel to reach a maximum theoretical speed of 5.8 Gbps, which is 2.4 times faster than Wi-Fi 6 or 6E.
