Here are key points about the ASROCK X370 PRO4.
Large VRM: The X370 Pro4 is an X370, which most people feel is meant for AMD's high-end Ryzen 7 processors, and since it needs to support overclocking those processors it means that overclocking AMD's Raven Ridge CPUs is very easy on this motherboard, in regards to the VRM. The SoC phases are also three phases, which is above the average, and should facilitate easy iGPU overclocking.
Dual M.2: One M.2 slot is routed to the CPU x4 PCI-E 3.0, and that slot shares its bandwidth with the x4 electrical slot, so you can technically use AIC storage devices on that slot. The second M.2 slot only supports SATA based M.2 drives, but there are a ton of SATA M.2 drives.
Dual RGB Headers: The motherboard has an RGB header and an AMD FAN LED1 header, but they are pretty much both RGB LED headers, and that is a good thing since the motherboard has no built-in RGB LEDs.
Legacy iGPU Outputs: The rear IO features HDMI, DVI, and VGA (D-Sub) on the rear IO to facilitate many different types of monitors. Many current B350 and X370 motherboards do not offer video outputs on the rear IO, and some of those that do only offer modern connections like HDMI and DisplayPort.
No USB 3.1: Although the motherboard has that light blue USB housing on the motherboard, it doesn't offer USB 3.1 (USB 3.1 Gen 2), rather only USB 3.0 (USB 3.1 Gen 1).
The ASROCK X370 Pro4 is one of their newer motherboards targeting Raven Ridge buyers. It offers a slightly expanded feature set compared to B350 motherboards, stronger iGPU output support, and a beefier SoC VRM for the iGPU.
It's a solid option for a more enthusiast Raven Ridge build. ASRock's Pro series lineup is basically their gaming series but with less effort put into aesthetics. For starters, this is one of the few motherboards I have reviewed this year without any type of LEDs; the motherboard is totally black.
I should mention that my motherboard came with the ability to boot the new CPUs, although that is not promised (unless it has a sticker that promises 2000 series support). Raven Ridge CPUs require updated UEFIs with AGESA code 126.96.36.199 to work.
Otherwise, you need to flash the BIOS on the motherboard with an older CPU (which AMD will loan you for free). AMD has new UEFIs for all of their AM4 motherboards that fully support the new CPUs. If you are looking for a motherboard for Raven Ridge with features optimized for Raven Ridge, give the X370 Pro4 a look.
