Today, we’ll be taking a look at the ASRock B550 Phantom Gaming-ITX/ax motherboard. This is one of the first mini-ITX motherboard we’ve tested in our labs that features the B550 chipset, and supports all 3rd Gen Ryzen processors.

What makes B550 motherboards so appealing, is the fact that it’s cheaper than the X570, it supports PCIE 4.0, and comes with good overclocking options, as well as support for future Ryzen 4000 CPUs. Now that’s something which we didn’t expect from a mainstream chipset. But there is one more thing that this motherboard has, that makes it even more attractive. What is it? … Well, the ASRock B550 Phantom Gaming-ITX/ax is the only ITX motherboard that I’ve seen that features two M.2 slots for SSDs. One Hyper M.2 (PCIE 4.0/Gen4) and the other, Ultra M.2 (PCIE 3.0/Gen3). Most mini-ITX motherboards that I’ve come across only come with one M.2 slot.
