GIGABYTE B450M K DDR4 AMD Motherboard

The GIGABYTE B450M K is a Micro ATX motherboard built on the AMD B450 chipset, designed for the AM4 socket and compatible with a wide range of AMD processors including Ryzen 5000 Series, Ryzen 5000 G-Series, Ryzen 4000 G-Series, and 1st through 3rd Generation Ryzen processors, as well as Athlon processors with Radeon Vega Graphics. Its compact 23.3 cm x 19.8 cm footprint makes it a practical choice for space-conscious builds without sacrificing connectivity or feature depth. Memory support is handled through two DDR4 DIMM slots capable of accommodating up to 64 GB of system memory (up to 32 GB per DIMM). The board supports DDR4 speeds from 2133 MHz up to 3600 MHz in overclocked mode, with dual-channel architecture and compatibility with XMP memory profiles for straightforward performance tuning. Storage is served by a single M.2 connector (Socket 3, M key, type 2280) supporting both PCIe 3.0 x4/x2 NVMe and SATA modes, complemented by four SATA 6 Gb/s ports with RAID 0, RAID 1, and RAID 10 support via the chipset. For graphics output, onboard display connectors include one D-Sub port (up to 1920×1200 @ 60 Hz) and one HDMI 2.0 port (up to 4096×2160 @ 60 Hz) with HDCP 2.2 and HDR support, useful when pairing with APU-based processors. Connectivity on the rear panel includes four USB 3.2 Gen 1 ports, two USB 2.0 ports, a Gigabit Ethernet port powered by a Realtek GbE LAN chip, PS/2 keyboard/mouse port, and three audio jacks. Audio is handled by a Realtek High Definition Audio CODEC supporting up to 7.1-channel output. The board features Smart Fan 5 with five temperature sensors and two hybrid fan headers supporting both PWM and voltage-mode fans. Fan control and system monitoring can be managed through GIGABYTE’s APP Center software suite, which includes EasyTune, @BIOS, Smart Backup, System Information Viewer, Q-Flash, and Xpress Install utilities. A TPM header (2×6 pin, for GC-TPM2.0_S module) is present internally for security-conscious deployments. The AMI UEFI BIOS occupies a 128 Mbit flash chip and conforms to PnP 1.0a, DMI 2.7, WfM 2.0, SM BIOS 2.7, and ACPI 5.0 standards. Windows 11 64-bit and Windows 10 64-bit are officially supported.
