Overview
The GIGABYTE B650 UD AX is a full-size ATX motherboard built on AMD's AM5 platform with the B650 chipset, designed to support AMD Ryzen 7000, Ryzen 8000, and Ryzen 9000 Series processors. It brings a capable feature set to mid-range builds, combining next-generation connectivity, fast storage, and reliable power delivery in a package suited to both gaming and productivity workloads. Power delivery is handled by a 6+2+2 phase digital VRM solution, providing stable voltage regulation for Ryzen processors across the supported lineup. Memory is accommodated via four DDR5 DIMM slots in a dual-channel configuration, supporting non-ECC unbuffered modules in 1Rx8, 2Rx8, and 1Rx16 configurations with speeds rated up to 8000 MHz (OC). Both AMD EXPO and Intel XMP memory profiles are supported, enabling straightforward memory overclocking with compatible kits. Maximum supported memory capacity is 256 GB. Storage options are generous for the B650 tier, with three M.2 Socket 3 connectors — one operating at PCIe 5.0 speeds and two at PCIe 4.0 — alongside four SATA 6 Gb/s ports for traditional drives. The primary PCIe x16 slot supports PCIe 4.0 x16 mode with Ryzen 7000 and 9000 Series CPUs, while Ryzen 8000 Series processors run it at x8 or x4 depending on the specific variant. An EZ-Latch mechanism on the PCIe x16 slot simplifies graphics card installation and removal. Wireless connectivity is provided by an 802.11ax (Wi-Fi 6) adapter capable of up to 2.4 Gbps theoretical throughput, paired with Bluetooth 5.0. A Gigabit Ethernet port (RJ-45) is also included at the rear panel. Video output options include one DisplayPort and one HDMI port, catering to builds using integrated Radeon graphics in Ryzen 8000 Series APUs. The rear I/O panel features one USB Type-C port (USB 3.2 Gen 1), two USB 3.2 Gen 2 Type-A ports, six USB 2.0/1.1 ports, a PS/2 keyboard/mouse port, two SMA antenna connectors, and three audio jacks. Internal headers include USB 3.2 Gen 1 (Type-C and Type-A), three USB 2.0/1.1 headers, addressable RGB Gen2 and standard RGB LED strip headers, and a TPM header. Fan management is handled by GIGABYTE's Smart Fan 6 system with multiple temperature sensor inputs and hybrid fan headers supporting FAN STOP functionality. Q-Flash Plus allows BIOS updates without a CPU or memory installed.
