ASUS Prime Z390M Plus

The ASUS Prime Z390M Plus is the cheapest of three mATX ASUS Z390 motherboards and visually looks similar to the Prime Z390-P in terms of aesthetics with the white patterning on a black PCB. The Prime Z390M Plus features the same set of white and black slim heatsinks on the power delivery and has a full-length PCIe 3.0 x16 with a second full-length PCIe 3.0 x4 slot offering up to two-way CrossFire multi-graphics card support. This board like the Prime Z390-A has two M.2 slots with both supporting PCIe 3.0 x4, but only one offering SATA compatibility. Also included are four SATA ports offering support for RAID 0, 1, 5 and 10 arrays.

On the Prime Z390M Plus, memory compatibility stretches to DDR4-4266 which is impressive for an entry-level offering and ASUS has really upped their game in the memory speed stakes. This is provided over four available RAM slots with a maximum supported capacity of up to 64 GB.

The rear panel has two USB 3.1 Type-A ports and four USB 3.0 Type-A ports and features a pair of video outputs which consists of a DVI-D and HDMI connector. A separate PS/2 keyboard and mouse port are located on the left side, with an Intel I219V Gigabit networking controller powering the single LAN port and older Realtek ALC887 HD audio codec controlling the available 3.5 mm audio jacks. 

The ASUS Prime Z390M Plus pricing and availability is currently unknown but this model is likely to be the cheapest of the ASUS mATX sized options with a complete focus on offering value over premium chipset features such as the TUF gaming series offers, and this particular model looks to offer users a more value-focused mATX sized entry point onto the Z390 chipset.

    Are they ALL made in China? What happened to the ones made in Taiwan from a few gens ago? :/

    Unfortunately, I cannot confirm this. The ASRock Z390 Taichi I have in my hands says 'designed in Taipei', but that's about it.

    Gigabyte apparently has a factory in Taiwan. It seems all the rest moved production to China.

    The MEG Z390 Godlike looked like such an interesting board until I checked the MSI Specifications page and realised it actually does not have the PLX chip as suspected. The PCI Express slots on the board are configured as 16x / 4x / 8x / 4x instead of 16x / 16x / 8x / 4x or 16x / 8x / 16x / 4x. It seems after PLX sold to whomever owns them now, that the price hike stopped their usage on consumer boards completely.

    I really really hope somebody comes out with a board that has a PLX chip on board.

    The Supermicro C9Z390-PGW has a Broadcom 8747 PLX PCIe switch :)

    It would be a nice touch including in next MB review what pheriferals stop funcioning when too much PCI-E lanes are used. Some motherboards disable SATA ports when M.2 slot are used; others may require limiting bandwith to one PCI-E slot... etc. Before byuing a motherboard I would like to be warned that is not possibile to use all the features they are advertising.

    I wish we would get better thunderbolt support. Only one board has it built in? I'm thinking of a Taichi board and see a Thunberbolt AIC connector in the manual, but then I can't really find enough good quality posts of people having success putting it to use. I'd like to get a new external nvme ssd thunderbolt drive to run my vms off of so I can more easily take them on the road with me and use from my notebook.

    Certain Gigabyte boards, e.g. Z390 Aorus Pro WiFi, seem to be using Intel's Z390 CNVi, but aren't listed in the article.

    I'm going to be updating tomorrow with more information; been working on getting one of the board reviews ready for the end of the week :)

    Will be adding these in tomorrow (not at a PC currently) - We didn't have the information available prior to writing
