We preferred the positioning of the NVMe drive without having to dump heat from the video card. You can effortlessly pair the board with the Ryzen 9 5900X and the rest. We found this to be the ultimate combination of efficiency and power.

Overall, the features & layout of the B550-A Pro were sublime. Our tester felt that there is nothing to complain about it. Likewise, the design of the Gigabyte B550 Aorus Pro motherboard is elegant.

We liked the tones used on it, and Aorus motherboards come with stunning designs containing the right amount of elements. The looks of the Aorus Pro have few premium aesthetics.

According to the maker, it is the first product to come with those trademarks. For example, users can notice the neatly done aluminum finish on the VRMs. Besides, it also has a black PCB. You can find the integrated lighting on the board at the audio location.

Users can add RGB light by getting them additionally. Of course, they also have to plug it on the onboard headers. This unit is way ahead in terms of design and the layout compared to most units that we have reviewed having the same price.

The connectors, slots, and sockets come in black and grey tones. We also like the plastic shroud on the VRM heatsinks. You can find 4 DRAM slots near the right socket. The capacity of the exceptional memory at 128GB running to DDR4 4266.

Though that figure is slightly lower than others compared in the market, however, we are delighted to let you know that it can seamlessly reach the AMD ‘sweet spot’ DDR4 3600/3733. On the whole, the features & layout are stunning, with good features placed in there.
