Verdict

The Gigabyte Z490 UD is an ATX motherboard built on the Intel Z490 chipset, supporting 10th and 11th Gen Intel Core processors via the LGA 1200 socket. It features a direct 11+1 phase digital VRM with an enlarged heatsink for stable power delivery, four DDR4 slots supporting up to 128GB at 4500MHz (O.C.), and dual M.2 PCIe Gen3 x4 connectors. Key pros include its 'Ultra Durable' build quality with PCIe armor, Q-Flash Plus for BIOS updates without a CPU installed, and RGB Fusion 2.0 support for custom lighting. However, common cons include the lack of a rear USB Type-C port, limited high-speed USB-A connectivity compared to premium boards, and a basic Realtek ALC887 audio codec.
