Gigabyte B650M H M-ATX Motherboard

The GIGABYTE B650M H is a Micro ATX motherboard built on the AMD B650 chipset with an AM5 socket, designed to support AMD Ryzen 7000, Ryzen 8000, and Ryzen 9000 series processors. Its compact 23.0 cm × 22.5 cm form factor makes it a practical choice for space-conscious builds without sacrificing platform capability. Power delivery is handled by a 5+2+2 phase digital VRM solution using low RDS MOSFETs, providing stable voltage regulation under sustained CPU loads. The board accommodates two DDR5 DIMM slots in a dual-channel configuration, supporting speeds from 4400 MT/s up to 7200 MT/s (OC), with a maximum capacity of 128 GB (64 GB per slot). Both AMD EXPO and Intel XMP memory profiles are supported for straightforward memory tuning. For storage, a single M.2 connector (M2A_CPU, Socket 3, M-key, types 2280/2580) supports PCIe 4.0 x4 NVMe SSDs when paired with Ryzen 7000 or compatible Ryzen 8000/9000 processors. Four SATA 6 Gb/s ports are also onboard, and RAID 0, 1, and 10 configurations are available for both NVMe and SATA arrays. The primary PCIe x16 slot runs at PCIe 4.0 x16 with Ryzen 7000 and Ryzen 9000 processors, while Ryzen 8000 Phoenix variants operate at x8 or x4 depending on the specific SKU. An additional PCIe 3.0 x1 slot is provided via the chipset. GIGABYTE's EZ-Latch mechanism enables tool-free GPU removal. Display output is available through one DisplayPort 1.4 (up to 3840×2160 @ 144 Hz) and one HDMI 2.1 port (up to 4096×2160 @ 60 Hz), both dependent on processor integrated graphics support. Audio is managed by a Realtek High Definition Audio CODEC supporting up to 7.1-channel output, with a dedicated audio noise guard separating analog circuitry at the PCB level. Networking is provided by a Realtek Gigabit Ethernet controller (1 Gbps/100 Mbps/10 Mbps) with bundled bandwidth management software. USB connectivity includes 2× USB 3.2 Gen 1 and 4× USB 2.0 ports on the rear panel, plus internal headers for additional USB 3.2 Gen 1 and USB 2.0 expansion. The rear I/O also features a PS/2 port and a dedicated Q-Flash Plus button for BIOS updates without an installed CPU, memory, or GPU. Smart Fan 6 technology supports PWM and DC fan modes across three onboard fan headers, with per-header curve configuration and a FAN STOP feature. ARGB and standard RGB LED headers are included for lighting customisation. The board ships with a 3-year warranty.
