Our Rating :
Price when reviewed : £155

Keenly priced and rammed with features, this is an excellent foundation for up-to-date Intel PCs


  • Packed with features
  • At the affordable end of the Z390 spectrum
  • Excellent selection of audio ports


  • Performance not tip-top
  • Could use more USB connectors

The ability to stick one of Intel’s latest ninth-generation processors into an eighth-gen Z370 motherboard hasn’t stopped an avalanche of new Z390 motherboards, even with this chipset’s lack of significant feature upgrades.

Nonetheless, there are models we’d be quite happy to build a Coffee Lake Refresh system around: the £296 Asus ROG Maximus XI Hero WiFi is a fitting base for high-end PCs, and now MSI’s MPG Z390 Gaming Edge AC successfully delivers a wide feature set for a far more accessible price.

MSI MPG Z390 Gaming Edge AC review: Design

It’s a full-size ATX board with Intel’s LGA1151 socket, so will hold any mainstream Coffee Lake and Coffee Lake Refresh CPU. It’s not entirely without visual flair – the rear I/O panel is concealed by an angular cover, and the underside of the right edge is decorated with controllable RGB lighting – but, generally, the inoffensive black, white and grey colour scheme will help it blend in neutrally to any sufficiently sized case.

MSI MPG Z390 Gaming Edge AC review: Features and connectivity

There are no built-in heatsink covers for either of the M.2 slots, but then the heat-spreading properties of these rarely improve performance in practice. The inclusion of two such ports, both capable of switching between PCIe and SATA modes, is a strength in itself, as are the generous three PCIe slots and three PCIe x1 slots. The former can support two-way SLI and three-way CrossFire GPU setups, too, and an SLI bridge comes in the box.

Admittedly, the topmost two PCIe x1 slots are likely to get covered up by a graphics card, unless it’s a slimline model. That might prove troublesome if you want to add a lot of expansion cards, but these are often installed to make up for shortcomings in the motherboard – and there’s little reason to buy a Wi-Fi card or a sound card here as well.

For one, there’s the star feature of integrated 802.11ac Wi-Fi, with Bluetooth 5.0 functionality coming from the same component. This only requires a couple of screw-on antennas at the rear I/O panel, not a larger wired antenna that needs placing elsewhere, and helpfully ensures your PC can stay connected without any extra dongles or adaptors, should you be unable to use a wired Ethernet connection (although the standard Gigabit Ethernet port is present and correct, too). Bluetooth, often overlooked in the desktop space, is also handy for connecting things such as wireless headphones.

An excellent selection of audio ports also cuts down on the benefit of a dedicated sound card. In addition to the usual 3.5mm line in, line out and microphone jacks, the MPG Z390 Gaming Edge AC provides rear speaker and C/SUB jacks as well as an optical S/PDIF port, so hi-fi and surround-sound speakers can be set up without fuss. MSI has opted for the up-to-date Realtek ALC1220 audio codec too, not an older version as cheap boards often do.

We wouldn’t have declined a few more USB connectors: the I/O panel totals two USB 2 ports, two USB 3 ports, one USB 3.1 port and a single USB Type-C. That will be enough for most home users, in fairness, but the slightly cheaper Gigabyte Z390 Gaming SLI has a full six USB 3 ports and two USB 3.1 ports.

Then again, it also lacks Type-C, S/PDIF and onboard Wi-Fi connectivity, so we’d say MSI’s motherboard has the advantage overall.

MSI MPG Z390 Gaming Edge AC review: Performance

Performance testing showed once again that, all other things being equal, your choice of motherboard won’t affect performance much. Even with Intel’s mighty Core i9-9900K, running our 4K benchmarks resulted in the MPG Z390 Gaming Edge AC-based system scoring just one point lower than the aforementioned ROG Maximus XI Hero WiFi: 329 to 330.

That said, Asus’s board seems better for ambitious overclocking. With the ROG Maximus XI Hero WiFi and an AIO watercooler, we got the Core i9-9900K to a stable 5.0GHz on all eight cores, but using the same settings with the MPG Z390 Gaming Edge AC meant crashes during the benchmarks.

The best we could manage was 4.9GHz with a 1.39v VCORE, so if you do want to push your ninth-gen Intel CPU to its extremes, it’s probably worth spending more on the motherboard.

Still, at least our trial-and-error testing was made easier by MSI’s industry-leading UEFI design. There haven’t been any big changes from the Z370 to Z390 generations, which is fine by us – the grid-based main menu has long felt like the most user-friendly among all the big motherboard manufacturers, although there are plenty of tuning options for experienced overclockers to dive into.

Mouse controls also feel a lot more reliable and intuitive than in, say, Asus’s BIOS, where it often ends up less frustrating to use the arrow keys for navigation instead.

MSI MPG Z390 Gaming Edge AC review: Verdict

Best of all, the MSI MPG Z390 Gaming Edge AC is one of the lower-priced ATX Z390 motherboards, even if that does arguably say more about Z390 pricing in general than it does about this particular model.

There are only a few more affordable ones, and they are invariably less well equipped, whether it’s I/O panel connectivity, a lack of Wi-Fi or the use of older audio codecs. As such, the MPG Z390 Gaming Edge AC is easy to recommend.
