Combo platform

This bundle pairs an MSI X870 GAMING PLUS WIFI motherboard with an AMD Ryzen 9 9950X processor. The board uses the AM5 socket and X870 chipset to support Ryzen 9000, 8000 and 7000 series CPUs. The included 16 core, 32 thread Zen 5 CPU reaches a 5.7 GHz max boost and provides 64MB L3 cache. It targets enthusiasts building a high-end desktop for gaming or content creation.

Before ordering

Verify that your power supply includes two 8 pin CPU connectors for the 14+2+1 Duet Rail power system. The motherboard offers four 288 pin DDR5 slots with a 256GB maximum capacity in dual channel mode; only non-ECC unbuffered modules are supported. JEDEC speeds run at 4800 to 5600 MT/s while overclocked profiles can reach 8200+ MT/s depending on DIMM population. Ensure your chassis can accommodate an 8 layer PCB with extended heatsinks.

Sustained operation

The 60A SPS VRM uses MOSFET thermal pads rated at 7W/mK alongside choke pads and an EZ M.2 Shield Frozr II to manage heat during long workloads. PCIe 5.0 x16 from the CPU and Gen 5 x4 M.2 storage maintain bandwidth without throttling. The Realtek 8126VB 5G LAN and Wi-Fi 7 controller provide stable network throughput for extended sessions. Audio is handled by the Realtek ALC897 codec delivering 7.1 channel output.

Questions about this item

Does the board need both 8-pin CPU power connectors filled?

The 14+2+1 Duet Rail Power System uses dual 8-pin CPU power connectors for full current delivery to the 16-core processor.

What is the fastest M.2 slot and which drive lengths does it take?

M.2_1 runs from the CPU at PCIe 5.0 x4 and accepts 2280 or 2260 drives.

Can I run four DDR5 modules at the top overclocked speed?

With two slots populated the board supports up to 6400+ MT/s; four slots lowers the maximum further.
