NITRO+ X870EA PhantomLink combo

The Sapphire NITRO+ X870EA PhantomLink motherboard arrives paired with the AMD Ryzen 7 9800X3D processor. The CPU brings 8 cores and 16 threads built on the Zen 5 architecture with 96 MB of 3D V-Cache. Together they target enthusiasts who want high frame rates in 2K and 4K titles plus a clear AM5 upgrade path.

16+2+1 90A power and full-coverage cooling

A 16+2+1 phase design rated at 90 A per phase feeds the processor through a quick-release heatsink armour that covers the VRM, chipset and M.2 slots. The thermal solution is described as nitrogen-ready and includes ARGB lighting on the backplate. Wi-Fi 7 and Bluetooth 5 controllers share the rear I/O alongside a 5 GbE wired port.

PhantomLink back-connect and sustained loads

The exclusive PhantomLink interface lets a compatible graphics card plug in from the rear, removing front-facing power cables and improving case airflow. Dual PCIe 5.0 M.2 slots and dual USB4 40 Gbps ports keep storage and peripheral bandwidth high during long sessions. The CPU supports a 5.2 GHz max boost clock and DDR5 5600 base memory with overclocking headroom to 8400 MT/s.
