In-depth analysis of the X870 AORUS INFINITY

Taking it a step further, the AORUS INFINITY is a true beast, designed specifically for processors with 3D V-Cache . The first thing that catches the eye is its cutting-edge design with iridescent effects and a socket layout rotated 90 degrees, which changes the usual component arrangement. Its power system is massive, featuring an 18+2+2 phase SPS design with 110A output , ideal for those who aren't afraid of extreme overclocking.

  • Storage management: It features a main M.2 5.0 connector compatible with 2580 and 25110 form factors, as well as other chipset-managed slots with tool-less heatsinks.
  • Rear connectivity: The panel is very comprehensive, including USB4 Type-C with DisplayPort support, USB 3.2 Gen 2 ports, and an audiophile-friendly S/PDIF optical output.
  • Network and Audio: Build a controller Realtek RTL8126 for 5Gbps LAN and the Realtek ALC1220 audio chip, ensuring professional sound and network quality.

One very interesting detail is the Ultra Durable PCIe Armor reinforcement on the backplate, which prevents the slots from bending with heavy graphics cards, along with the EZ-Latch Up technology to remove the graphics card without struggling with the plastic tabs.
