ASRock was seen with five B450 boards at the Computex 2018. Some are ATX, while others are either Micro-ATX or Mini-ITX. ASRock has released at least one model for each format. In addition to three boards from the Pro series, two models of the Fatal1ty gaming series were shown as well. The B450M Pro 4 and the B450M-HDV are produced in Micro ATX format, with the Pro4 basically offering better features. The maximum RAM expansion amounts to 64 GB instead of “only” 32 GB. But even with the power supply of CPU and RAM Pro4 is the HDV slightly superior to the higher number of phases.
A common feature, however, are the four SATA 6GBit / s sockets and also an M.2 M-Key connection (connected via the CPU) are identical. However, the B450M Pro4 still offers an additional M.2-M-Key slot, but then goes over the chipset to the factory. Two digital and one analogue graphic output are included, whereby the Pro4 can settle with two native USB 3.1 Gen2 interfaces.
And then there’s the B450 Pro4, which come in form of ATX dimensions and compared to his little brother has more expansion slots and offers two additional SATA ports. The B450 Gaming K4 is based on the same features of the B450 Pro4, except that the PCB has been redesigned and RGB LEDs have been installed. For mini-ITX sympathizers, the B450 gaming ITX / ac is excellent for building a small Ryzen system. Six coils take care of the VCore, two coils take care of the SoC voltage. For reasons of space, two DDR4 UDIMM banks are used and can accommodate up to 32 GB of RAM.
Four times SATA 6 Gb / s in vertical orientation can also be seen. For installing a discrete graphics card, for example, the PCIe 3.0 x16 slot is ready, which of course gets its lanes from the CPU / APU. Two USB 3.1 Gen2, USB 3.1 Gen1 and USB 2.0 and two digital graphics outputs, one PS / 2, Gigabit LAN and the usual sound ports are visible on the I / O panel. There is also a WLAN ac module is on board. There is currently no information on their availability and prices.
