A decent mATX board for your new Trinity HTPC.
The F2A55-M allows for easy overclocking, both through the UEFI BIOS and through the software. The UEFI BIOS, in case you don’t to fiddle around too much, has a one click button on the main interface that will allow you to choose an Extreme Overclock preset that automatically overclocks the A10-5800K from the stock 3.8GHz to 4.3GHz. That’s smack in the middle of the default turbo boost speeds of the A10-5800K which goes up to 4.3GHz. The forced overclock of 4.4GHz isn’t much faster either, so if you want a simple solution without any headaches, ASUS has taken care of it.
Otherwise the below benchmarks show a 4.4GHz on CPU and 1085MHz on GPU overclock on the A10-5800K @ 1.5v settings.
The ASUS F2A55-M is a decent motherboard with average performance. What makes it different from others is the UEFI BIOS, if you want to fiddle around in there, plus the package of ASUS software that cares of various things from overclocking to setting custom fan speeds to continuous monitoring for anti-surge protection.
Sure, there are no SATA III ports or Gen 3.0 PCIe slots, but that’s not the point of building a budget HTPC or low-powered gaming system. In that sense, there’s little to fault with the ASUS F2A55-M, and if you’re in the market for a solid motherboard for an AMD Trinity APU based small system, then ASUS definitely gives you a nice choice.
