Editor's Pick: If you're building a new gaming or office PC on the AM5 platform, this board covers all the essentials. The 7-phase power delivery handles Ryzen 9000 series CPUs with ease for daily use, and the two DDR5 slots support overclocking up to 8000+ MT/s, so memory performance is solid. It comes with a PCIe 4.0 x16 slot and two M.2 Gen4 slots, leaving plenty of room for GPU and SSD upgrades. The onboard 2.5G Ethernet port keeps latency low for large file transfers on your local network or cloud gaming, and the clean layout makes it easy to work with in a compact mATX case.
