Socket AM5 motherboard paired with a 16-core Ryzen 9 9950X3D CPU, DDR5 up to 8400 MT/s, PCIe 5.0 graphics and storage, Wi-Fi 7 and 5G LAN
CPU +R9 9950X3D
This bundle pairs the MAG X870 TOMAHAWK WIFI motherboard with a Ryzen 9 9950X3D processor for Socket AM5 systems. The CPU delivers 16 cores and 32 threads based on Zen 5 architecture with a 5.7 GHz max boost and 64 MB L3 cache. The board provides an 80A SPS VRM, four DDR5 slots supporting up to 256 GB, and dual-channel memory architecture. It targets enthusiasts who want a high-core-count platform with modern connectivity.
Verify that the motherboard BIOS version supports the Ryzen 9 9950X3D out of the box or plan a USB BIOS FlashBack update. Confirm your CPU cooler mounting pattern matches AM5 and that its height clears the extended PWM heatsink. Ensure the power supply provides an 8-pin plus 4-pin EPS connector for the 80A VRM. The four 288-pin DDR5 slots accept unbuffered non-ECC modules up to 8400 MT/s when overclocked.
The 80A SPS VRM and extended heatsink are designed to keep the 16-core processor at full speed during prolonged workloads. Dual PCIe 5.0 M.2 slots from the CPU and two additional slots from the chipset maintain bandwidth for storage arrays under continuous traffic. Realtek 5G LAN and Wi-Fi 7 with a 320 MHz channel handle persistent network streams. The USB 40G port sustains 40 Gbps transfers for external devices.

같은 제품군에서 메모리·쿨러·클럭이 다릅니다 — 결정 전에 비교해 보세요.
The box contains the MAG X870 TOMAHAWK WIFI motherboard and the Ryzen 9 9950X3D processor. You must buy DDR5 memory modules, a CPU cooler, storage drives, a graphics card, a power supply and a case separately.
The board supports up to 256 GB across four slots in dual-channel mode. For best performance install a matched 2-module kit rated at 8400 MT/s or higher; the CPU officially supports DDR5-5600.
The 16-core CPU can raise up to 5.7 GHz on active cores when thermal and power headroom allows, giving faster single-thread response in games and lighter workloads.
