ASUS ROG Crosshair X870E Hero

The ROG Crosshair X870E Hero is ASUS's flagship AM5 board for Ryzen 9000, 8000, and 7000 series desktop processors, built around the AMD X870E chipset and aimed at enthusiasts who want the strongest VRM and I/O available on the platform without moving to a workstation-class board. It pairs a 22-phase, 110A SPS power stage design with dual PCIe 5.0 x16 slots and five M.2 sockets, giving builders headroom for high core-count Ryzen 9000 X3D chips and multiple Gen5 SSDs at once.

The board runs an 18+4 (22-phase total) power stage configuration using 110A SPS MOSFETs for Vcore, backed by a large VRM heatsink and heat pipe assembly rated for roughly 1,980A of combined delivery. This level of power delivery is aimed squarely at overclocked Ryzen 9000 X3D and 9950X-class chips rather than typical mainstream builds, which is more headroom than most buyers will ever use. Four DDR5 DIMM slots support up to 192GB total capacity, with AMD EXPO profiles enabling overclocked speeds up to roughly DDR5-8200 on Ryzen 9000/7000 series processors and DDR5-8600 on APU-based chips, once the CPU's memory controller and DIMM quality allow it. Two PCIe 5.0 x16 slots are available, with the primary running at x16 or x8 while the secondary supports x8/x4 bifurcation for multi-GPU or add-in-card setups. Storage is handled by five M.2 sockets: three PCIe 5.0 x4 slots wired directly to the CPU for maximum SSD throughput, plus two PCIe 4.0 x4 slots from the chipset. Networking includes both 5GbE and 2.5GbE Ethernet controllers alongside Wi-Fi 7 (802.11be) with 2x2 320MHz channel support and Bluetooth 5.4. Audio runs through a Realtek ALC4082 codec paired with an ESS Sabre9219 DAC for higher-end analog output, and the rear I/O includes BIOS FlashBack and Q-Release for tool-free GPU removal. Against the Gigabyte X870E AORUS INFINITY NEXT already in this catalog, the Crosshair X870E Hero trades some of Gigabyte's raw phase count for tighter ASUS BIOS tuning tools and a stronger dual-LAN setup, while its five M.2 slots edge out most competing X870E boards for SSD expansion.
