Ready-built AM5 platform for gaming

This bundle pairs an MSI MAG X870E TOMAHAWK WIFI motherboard with a Ryzen 7 9800X3D processor. The board uses the AMD X870E chipset and AM5 socket to support Ryzen 9000, 8000 and 7000 series CPUs. Four DDR5 slots accept up to 256 GB of memory running at JEDEC 5600 MT/s or overclocked speeds up to 8400 MT/s.

Tool-less hardware installation aids

EZ PCIe Release unlocks the graphics-card slot with a single button press. EZ M.2 Shield Frozr II secures M.2 SSDs in 2280, 2260 or 22110 sizes without screws. A built-in USB 40G port provides 40 Gbps throughput for external storage or docks.

CPU 3D V-Cache defines gaming throughput

The included Ryzen 7 9800X3D carries 3D V-Cache technology that directly raises frame rates in cache-sensitive titles. If your workload benefits from that extra L3 capacity, this combo matches the motherboard's PCIe 5.0 and DDR5 headroom to the processor's strength.

Questions about this item

Will the EZ M.2 Shield Frozr II need any tools or thermal pads replaced when I swap an M.2 SSD later?

The EZ M.2 Shield Frozr II uses a tool-less latch so you can remove or install an M.2 drive without screws. The heatsink stays attached to the board; you only lift the shield, swap the SSD, and snap it back down. No extra thermal pads are required unless you peel the original ones off.

Which M.2 slot hits its throughput ceiling first when I run sustained PCIe 5.0 x4 writes?

M.2_1 and M.2_2 are wired to the CPU at PCIe 5.0 x4, so their limit is the drive’s own sustained write speed. M.2_3 and M.2_4 run through the chipset at PCIe 4.0 x4, so they saturate earlier at roughly half the bandwidth of the CPU-attached slots.

How loud does the VRM fan get and what is the 5G LAN controller’s power draw when the system runs all day?

The board uses a fanless VRM heatsink, so there is no VRM fan noise. The Realtek 8126 5G LAN controller is a low-power PHY that draws only a few watts under load, adding negligible heat to the chassis during continuous operation.
