Manufacturer description
The GIGABYTE B650 Eagle AX is an AM5 ATX motherboard built for Ryzen 9000, 8000, and 7000 Series processors, and it covers the essentials a mid-range AM5 build actually needs. Its 12+2+2 phase digital VRM and Advanced Thermal Design keep power delivery steady when you push a Ryzen 7 or Ryzen 9 chip under sustained load, while four DDR5 SMD DIMM slots support both AMD EXPO and Intel XMP profiles so your memory kit runs at its rated speed out of the box. Storage is the standout: three M.2 slots, one wired for PCIe 5.0 and two for PCIe 4.0, each covered by an M.2 Thermal Guard heatsink to stop…
