Our Verdict

The Asus ROG Maximus Z790 Hero is another excellent all round ROG offering from Asus. It's feature rich, reliable and refined, though it's priced at a level that takes the Maximus range well outside of the mainstream.

For

  • Dual Thunderbolt 4
  • for fast memory
  • PCIe M.2 card
  • Quality audio

Against

  • Expensive
  • No 5G or 10G LAN
  • Some U coolers may encounter compatibility issues

If you’ll forgive my turn of phrase, the Hero is the hero of Asus' Republic of Gamers motherboard range. It's the 'entry level' board, often the one that attracts the most attention, and most of the time it's the first one to be released. It s the top of the line Extreme and the overclocking focused Apex.

The Asus ROG Maximus Z790 Hero looks a lot like its Z690 predecessor and shares a similar feature set. That's not much of a surprise given that Z790 doesn't differ all that much from Z690, though Z790 does bring an increase in the number of PCIe 4.0 lanes and a 2nd gen optimized electrical design for helping with things like faster memory . For example, the Z690 Hero lists for DDR5-6400+, while the Z790 Hero s DDR5-7800+.

Along with faster memory and out of the box 13th Gen U , the Maximus Z790 Hero features very good connectivity , a quality VRM, and the best of Asus' hardware and firmware engineering expertise. 

At $629 / £649 / AU$1,199, it feels odd referring to the Z790 Hero as the entry level Maximus board. Whether it's electrical complexity, engineering challenges, component costs or profiteering somewhere along the retail chain, it's just the way it is. You don't get high-end motherboards from any manufacturer for cheap anymore.

Let's see if the Hero has what it takes to win the hearts, minds and dollars of the people.

The Maximus Z790 Hero features a good amount of mirror like finish, at least once you pull all of the protective plastic off. There's a good-looking RGB section atop the rear I/O section. It's very tastefully done. We've hit peak RGB and the days of retina burning disco light shows are hopefully now behind us. You do get three ARGB headers and one non-addressable RGB header, however, should you want it.

The board has 8x 4-pin fan/pump headers, a USB 3.2 Gen2x2 header (with up to 60w charging ) and headers for an additional four 3.2 Gen 1 ports and four 2.0 ports. There are onboard power/reset buttons too.

Along with six SATA ports, the Z790 Hero features five M.2 slots, with just three on the board itself. The layout of the on-board slots is excellent. I've never liked M.2 slots located underneath the primary PCIe slot where they absorb heat coming from a graphics card. The Hero gets it right. Well done Asus. 

The extra two M.2 slots come courtesy of a high quality PCIe add in card, complete with its own solid and heavy heatsink. One slot s PCIe 5.0, while the other s up to PCIe 4.0.

The VRM heatsinks are large, with a lot of surface area. Do note that while they conform to Intel's 'stay-out' socket area, they encroach enough to potentially interfere with large coolers. In my case, the tubing of my AIO cooler. The only way I could install it was to have the tubing on the memory slot side. If you do have a large cooler, for example one with protruding heatpipes, it's definitely worth doing a bit of research to ensure it will fit.

Speaking of coolers, the Z790 Hero again features holes for mounting legacy LGA1200/LGA115x coolers. 

Around the back we have top notch connectivity options. The inclusion of dual Thunderbolt 4 Type-C ports is a good value add, and they alone for some of the price of the board. Add to that six USB 3.2 Gen 2 ports and four Gen 1 ports and you’ll be set for a few years to come. 

The TB4 ports can carry a DP 1.4 signal, which gives you the option of triple display when added to the single HDMI 2.1 port.

Asus includes a high class audio solution including an ALC4082 audio and ESS Quad DAC. Wi-Fi 6E is expected and 2.5G Intel LAN is the baseline. The omission of 5G or 10G LAN is disappointing at this price, but I'll let you be the judge of whether that's important to you or not. With the advent of faster Wi-Fi 6 and 6E, is LAN as important as it once was? For a NAS , certainly, but there are a lot of gamers that don't use ethernet anymore.

System Performance

Gaming Performance

Benchmarking boards isn't as simple as it once was. Motherboard makers tend to play it fast and loose with power limits. Manually setting baseline parameters means over the top all core turbo levels are removed, though of course, you're free to enable them if your cooling allows it.

In system benchmarks, the Z790 Hero performed well, sitting at the top of the rankings, or close to it. It's no slouch in gaming either, standing up well against the other tested boards.

As is often the case though, the differences are quite small and often within a margin of error, which is a good indicator of a mature underlying platform. That's as it should be given the 13th Gen architecture and BIOS microcode aren't really different from 12th Gen Alder Lake and Z690.

Test rig

U: Intel Core i9 13900K
Graphics: Zotac GeForce RTX 3080 Ti AMP Holo
RAM: 2x 16GB G.Skill Trident Z5 DDR5-6000 C36
Storage: 2TB Seagate FireCuda 530
Cooling: Cooler Master PL360 Flux 360mm AIO
PSU: Corsair AX1000

When it comes to overclocking, your U will generally be cooling limited before the motherboard is stressed. Even a quality 360mm AIO nears its limit with a Core i9 13900K at stock! As for memory overclocking, that separates a good board with a good BIOS from a poor one.

I have a nice shiny set of G.Skill Trident Z5 DDR5-7200 (stay tuned for a review). It's not a given that every board can run at that speed reliably. The Hero certainly can, though in my case it required a high level of IMC voltage to do it. I think with a better U the Hero will be able to do more, and in fact its rated for DDR5-7800+. It's the best four-slot DDR5 board I've tested to date.

ROG boards always come with high expectations, and they very rarely disappoint. If you love ROG—and there are millions of you out there—you'll be right at home with the Asus Maximus Z790 Hero. Feel free to reliably overclock your K-series U with DDR5 7000+ memory. Chuck in a fast graphics card and future PCIe 5.0 SSD and you’ll be rocking a rig that will see you through 2024 and beyond.

It's the best four-slot DDR5 board I've tested to date.

It's a genuinely high end offering that doesn't lose all that much compared to the hyper-expensive top-end boards. Price wise, compared to the likes of the Maximus Extreme or MSI Godlike, the Z790 Hero is a relative bargain! But in the real world, as the entry level Maximus, it's an expensive proposition. You may well find that Asus' Strix or TUF boards offer what you need at a more attractive price point.

Apart from the omission of faster LAN, I cannot complain about the feature set. There's no doubt that forward looking features, such as Thunderbolt 4 and the add-in card with PCIe 5.0, add cost and complexity, but it's still a $600+ motherboard. Building a high-end system with an RX 7900 GPU is very expensive as we close in on 2023. Inflation sucks.

But ROG products are always tier, and there's an acceptable cost associated with that. If Asus keeps churning out well-designed boards with reliable BIOS, for fast memory, and forward-looking feature sets, there will be buyers for them. And you won't have any remorse.

The Verdict

The Asus ROG Maximus Z790 Hero is another excellent all round ROG offering from Asus. It's feature rich, reliable and refined, though it's priced at a level that takes the Maximus range well outside of the mainstream.
