After Gigabyte started adding new B 550 – also new B 450 boards, ASRock is now taking up this idea and has listed three new boards on its website. The B 450 M Pro4, the B 450 Pro4 and the B 450 M / ac, i.e. three budget boards. ASRock has marked the new models with an “R2.0” for the more recent revision, so that confusion can be excluded.

You really have to find the differences between the three new offshoots with a magnifying glass . In all three R2.0 models, ASRock has minimally expanded the CPU power supply and uses an additional performance level. For the rest of the equipment, the manufacturer continues to rely on the same features, but has given the new versions a different coat of paint that comes across as more modern.

So brings the ASRock B 450 Pro4 R2.0 is the only new ATX model, of course, with more expansion slots, namely two mechanical PCIe-3.0-x 16 – and that four PCIe 2.0 x1 slots. Six SATA 6GBit / s and two M.2 M-Key connections enable storage expansion. Of course, some USB interfaces of the current generations are also available (apart from USB 3.2 Gen2x2, of course).

As a smaller version, ASRock also offers the B 450 M Pro4 R2.0 in the more compact Micro-ATX format, where of course less space is available. But at least one PCIe 3.0 x 16, PCIe 2.0 x 16 ( mechanical) as well as PCIe 2.0 x1 for system expansion. In this case, too, there are two M.2 M-Keys and four natively connected SATA 6GBit / s ports. A common feature is the onboard sound with the Realtek ALC 892 / 897 and also the gigabit LAN port and three graphics outputs: HDMI 1.4, DisplayPort and D-Sub with the ATX and HDMI 1.4, DVI-D and D-Sub with the Micro-ATX model.

Third and last in the group is the ASRock B. 450 M / ac R2.0, which is very similar to the first version. ASRock has also added another CPU coil here. But apart from that, everything stayed with the tried and tested. One each PCIe 3.0 x 16 and PCIe 2.0 x 16 (mechanical), plus four SATA 6GBit / s, of course also four DDR4-UDIMM memory banks for a memory expansion up to 64 GB. In this case, however, only an M.2 M-Key interface with PCIe 3.0 x4 connection made it onto the board.

In addition to a Gigabit LAN socket, there is a WLAN-AC module is included, as you can see from the model name. Compared to the two Pro4 versions, the B 450 M / ac R2.0 has fewer USB ports and is limited to six USB 3.2 Gen1 and USB 2.0 .

In all three cases, no information on availability and price is available. However, the prices will very likely be close to the first versions.
