Power, connectors, outputs and dimensions identify this maker’s board and are not interchangeable with other cards using the same GPU. Confirm the exact retail revision, case clearance, PSU capacity and auxiliary cabling against the cited board documentation.
Architecture and compatibility notes
Intel Arc B-series desktop graphics uses the Xe2-HPG (Battlemage) architecture. 12 GB GDDR6, 192-bit and the board’s PCI Express link are dedicated card resources; the host platform determines the negotiated bus speed and width. Resizable BAR support is a platform feature, not a GPU power connector.
Windows 10/11 64-bit with the supported Intel Arc graphics driver. Use a UEFI platform with Resizable BAR enabled where supported; consult current Intel driver release notes. Linux support depends on kernel, Mesa and distribution versions.
