The best board for gaming PCs with 2K monitors

The Asus ROG STRIX B550-A GAMING is an example of a well-designed and well-equipped mid-range motherboard that can be used to build a fairly powerful 2K/4K gaming PC. It is part of the popular ROG STRIX overclocking line, but unlike most of its counterparts in the series, it is based on the mid-range AMD B550 system logic instead of the X570 chipset, and its average cost is around $200.

Powerful power converter

For this amount, a potential buyer gets a standard-sized ATX board with a high-end 14-stage power converter, high-quality alloy chokes and durable capacitors. In order to reduce overheating, the manufacturer has equipped the VRM zone and M.2 ports with additional radiators. And for the power ports and the video card slot, special reinforced mounts were used. The integration of the fourth generation PCI-E bus makes it possible to use high-speed M.2 SSDs with an average operating speed of around 5000 MB / s in the system. Support for DDR4 RAM with a maximum speed of 5100 MHz gives you a free hand in a future upgrade, when the price of such modules drops to the level of the current DDR-3200 memory.

No restrictions

It is worth noting that the use of the B550 chipset turned out to be the right decision, since when installing and overclocking the conditional Ryzen 7, the B550 does not heat up as much as the ROG STRIX boards with the X570 chipset. At the same time, it also reacts sensitively to auto-overclocking of the processor, without limiting it in any way. Plus, the B550 works great with Ryzen processors of all generations, sharpened for socket AM4. And now add to this cocktail the ability to pair video cards in Crossfire mode, high-quality ROG Supreme sound, built-in AI Networking optimization system, proprietary Armory Crate software, as well as numerous connectors for LED strips and water pumps, and you will get a perfectly balanced solution for gaming assemblies. near-top level.
