Gigabyte B450 Aorus Pro review - Product Showcase

 

This motherboard will get you six SATA 6 Gb/s storage ports (two horizontal and four vertical). Sitting left of the PCIe x16 slot are two M.2 slots as well, the first at x4 PCIe lanes Gen3 directly from the CPU thus 32 GB/sec of performance (primary slot), the secondary slot uses PCIe 2.0 and two lanes and this is much slower. There are USB 3.03.1 ports available through internal motherboard connectors, including USB 3.1 Gen 2, the fastest with a 10 Gbps connection. 

Here we can see the four DIMM slots which offer support for dual-channel DDR4 memory up to an advertised 2933 MHz (with Zen+). You can install a maximum of 64 GB in total. Given the nature of Ryzen and its CCX interconnect tied to the memory speed, we do recommend high-frequency memory. Please make sure you get a 3200 MHz kit if you are a gamer (which works just fine)

 Here you can see a 10cm type 2242/2260/2280/2210 slot. Delivering up to 32 Gb/s data transfer speed per connector. So it supports PCIe 3.0 x4 (Ryzen series processors). Nice thermal shield!  As stated, the second slot is not full speed, we'll demo this in the benchmark sessions. So be aware: the 2nd slot is shared with the chipset and is slower.
