Best AMD Motherboards For Gaming In 2023
Here are our picks for the best AMD AM5-based motherboards for gaming you can buy right now!
With the latest Intel Raptor Lake/Refresh and AMD Zen 4 lineup becoming the norm these days, it’s fair to say that users who are looking for an m-ATX motherboard will settle with either an LGA 1700 or AM5 socket respectively. Fortunately, there are a couple of chipsets present for both platforms, and even though they aren’t powerful enough to break world records, they surely offer plenty of ports and connectors for easy upgrades, a decently capable power delivery system, and satisfactory connectivity options.
Things To Consider When Buying A Micro-ATX Motherboard
Power Delivery: Unlike ATX motherboards, m-ATX motherboards generally don’t come with too many power phases. This is due to their compact design, but it’s always recommended to check the VRM and its components, especially when overclocking is one of the primary goals.
Component Compatibility: Always check for the type of RAM supported on the motherboard. It’s important to understand that with the transition from DDR4 to DDR5, some users might mistakenly buy a DDR4 motherboard which results in slightly lower performance. One should also check for PCI-E Gen 5.0 support and if the motherboard doesn’t lack M.2 connectors.
Connectivity: Connectivity can be divided into two types: Wireless and wired. Wireless connectivity indicates the presence of Wi-Fi and Bluetooth, while wired connectivity indicates the presence of a sufficient number of ports for peripheral connection. Faster USB ports are always preferred, particularly the Type C Gen2x2, which offers 20Gbps of speed.
Onboard Features: It can be difficult to find onboard troubleshooting features on m-ATX motherboards, but one should opt for the one that has Debug LEDs for easy troubleshooting. If the board also comes with power and reset buttons, then it should be given priority over those that don’t have them.
Cooling: VRM and the chipset should come with a decently sized heatsink for heat dissipation. Some motherboards also come with an M.2 connector shield which is even better. Also, plenty of chassis fans and AIO headers will ensure all-around cooling of the build.
