Professional users looking to purchase an ASUS Z390 board without much of the cost-upping controllers and aesthetics will probably be looking towards the Prime series. The Prime series offers an entry-level jump onto the chipset with bare minimum features, but like the rest of the Z390 chipset, they still support overclocking through the Z390 chipset and look to offer better value overall than the far-reaching gaming targeted boards.

ASUS Prime Z390-A

Starting with the premier entry-level Prime range, the ASUS Prime Z390-A is an ATX sized motherboard and features a white, silver and black design throughout. The board has a white rear panel cover and chipset heatsink, with integrated RGB on both with support for ASUS AURA Sync. The PCB has a white patterning which contrasts quite nicely and represents one of the more subtle looking ASUS Z390 options. The Prime Z390-A has three full-length PCIe 3.0 slots with two getting treated to ASUS Safe slot armor protection and the slots operate at x16, x8 and x4 from top to bottom. This means the Prime Z390-A officially supports two-way SLI and up to three-way CrossFire multi-graphics card configurations.

Memory capability comes from four RAM slots with support for DDR4-4266 and a maximum capacity of up to 64 GB. The storage solutions offered on the Prime Z390-A include two PCIe 3.0 x4 M.2 slots, with only one of them offering support for SATA drives; this seems to be a regular occurrence on the ASUS Z390 line-up. Also included are six SATA ports with the ability to operate RAID 0, 1, 5 or 10 arrays.

This top Prime Z390 model has a total of seven USB ports consisting of three USB 3.1 Gen2 Type-A, one USB 3.1 Type-C, two USB 3.0 Type-A and two USB 2.0 ports. A combined total of six audio ports split into five 3.5 mm audio jacks and single S/PDIF optical output controlled by a Realtek S1220A HD 8-channel audio codec, with a single LAN port being powered by an Intel I219V Gigabit networking controller. Finishing off the rear panel is a DisplayPort and HDMI 1.4b pairing of video outputs, as well as a handy PS/2 keyboard and mouse combo port.

The ASUS Prime Z390-A has an unknown MSRP as of yet and looks to offer users not looking to spending the additional budget on gaming related feature sets and flashy aesthetics; RGB is included on this model and white panels with RGB sets this system up really well from a design perspective. The native integration of USB 3.1 Gen2 into the Z390 chipset has been used well on this board and it looks to be a popular board for users not looking to use a WI-Fi enabled model.

    Still no mention of any Z390 boards with native Thunderbolt 3 (not AIC)! Has Intel given up on Thunderbolt for the PC world?

    If it's not integrated into the chipset, it's not really native as such. The ASRock Z390 Phantom Gaming-ITX/ac has a Thunderbolt 3 port on the rear panel, but that's the only one I'm afraid

    Oculus Rift requires 3 USB3 ports and doesn't accept any of them being connected to a hub, they all need to be connected directly into a raw port. I had to buy a dedicated 3GIO USB 3 board that added 6 useful extra ports. In my (yes, old) Gigabyte z87 mobo I also had issues using keyboard and mouse on USB 3 ports inside UEFI and some recovery softwares, so I had to buy a USB 2 mirror to connect them.

    Because of that, having USB 2 ports on front panel and nice quantity of USB 3 is what most differs mobos for me, given that all other features are nearly the same.

    ASUS Z390-A seems to be the best option. It has the important double USB2 ports, 5 USB3 ports and still has HDMI and DP for emergencies.

    I wish MSI had released a "godlike" board for the Ryzen series.

    You list the ASRock Z390 Phantom Gaming-ITX/ac above as an ATX board, but it's actually mITX. FYI
  • gavbon - Friday, October 19, 2018 - link

    I have gone through every page where the Phantom Gaming-ITX/ac is listed, but I can't see where it says it's an ATX board? Could you please be more specific? Are you viewing on mobile or desktop?

    It would be really helpful to break out one more criteria into a table: Type-C header for case-front ports.

    Helping a friend put together an i5 system and, knowing he'll keep it for a long time, am trying to get even with peripheral connectors (already has a monitor, so no using that as a hub). It's relatively easy to identify cases with a Type-C port, but that's pointless without a motherboard header. Having to go into each board's page to check is time-consuming.

    6 months later and I'm here for EXACTLY this reason. I've gone through probably 50 manuals over the past few days squinting to find this information. What a pain.
  • Synomenon - Thursday, October 18, 2018 - link

    So on the ASRock Z390 Phantom Gaming-ITX/ac, is the TB3 port on the rear using up lanes from CPU (making the only 16x slot, 8x only)?

    If it's not using lanes from the CPU, how will using that TB3 port (say with a USB3.1 Gen2 hub OR TB3 hub) affect all the other ports / IO on the board?
  • repoman27 - Thursday, October 18, 2018 - link

    Going off of what TweakTown published, it's a single-port Intel JHL6240 "Alpine Ridge" controller with a PCI 3.0 x2 connection to the PCH. So it won't affect the PEG lanes from the CPU. I'm amazed it's not Titan Ridge at this point though.
