The Gigabyte B450M K is a compact entry-level motherboard from the popular 2023 Gigabyte Ultra Durable line. It has been designed with long life in mind and has been manufactured with a variety of durable components to extend the life of the device. For example, double mounts for RAM modules, anti-sulfur coated resistors and a sealed PCB textolite. The device itself is equipped with a 6-phase power subsystem and does not have the usual VRM cooling.

The layout of the board includes 2 slots for DDR4 memory with support for XMP profiles, with a total capacity of up to 64 GB and a speed of up to 3600 MHz. The model belongs to the compact form factor micro-ATX, which can be easily installed in most computer cases of various types. The entry-level AMD B450K chipset is used as the system logic, the AM4 socket is provided for installing the processor, which is compatible with most AMD processors released from 2017 to 2022.

The only exception is the Ryzen 7000 chips released at the end of 2022, which work with AM5 system logic. The board handles network traffic using a Realtek gigabit LAN controller. For data storage, there are four classic SATA3 connectors and one M.2 connector for compact SSDs. There is one PCI-E slot for a video card, and an HDMI 2.0 port is located on the rear panel for connecting a monitor directly to the processor's integrated video card. All in all, Gigabyte might be a great choice for those looking for a low-cost, reliable, and versatile solution for an entry-level home or office PC without a discrete graphics card.
