Verdict

The Biostar Racing Z490GTN is a Mini-ITX motherboard built on the Intel Z490 chipset, supporting 10th and 11th Gen Intel Core processors via the LGA 1200 socket. It features two DIMM slots supporting up to 64GB of DDR4 memory with overclocking speeds reaching 4400+MHz, a single PCIe 3.0 x16 slot, and a 6+2 phase power design. Storage includes one M.2 PCIe 3.0 x4 slot (located on the rear), four SATA III connectors, and an additional M.2 E-Key slot dedicated to Wi-Fi/Bluetooth modules. Main pros include its compact form factor for SFF builds, stable performance with mild overclocking support, and an easy-to-use UEFI BIOS. However, it lacks an integrated Wi-Fi card, omits USB Type-C connectivity, and has tight clearance between the CPU socket and RAM slots that can interfere with large air coolers.
