Verdict

The ASUS A55BM-A/USB3 is a micro-ATX motherboard designed for the AMD FM2+ socket, supporting AMD A-series and Athlon processors with a maximum of four cores. It features the AMD A55 FCH chipset and two DDR3 DIMM slots that support up to 32GB of dual-channel memory with speeds reaching 2133 MHz (and up to 2400 MHz via overclocking). Key specifications include one PCIe 3.0/2.0 x16 slot, six SATA 3Gb/s connectors supporting RAID 0, 1, and 10, and multiple video outputs including HDMI (supporting 4K resolution on FM2+ APUs), DVI, and VGA. Its primary strengths lie in the ASUS 5X Protection suite, which offers enhanced durability through high-quality solid capacitors and digital power regulation, alongside USB 3.0 Boost for faster data transfers. However, notable drawbacks include its reliance on the older SATA 3Gb/s standard rather than the faster 6Gb/s, a limited total of two RAM slots, and the absence of a TPM connector.
