Gigabyte Z790 AORUS Elite AX Review: The Mid-Range Z790 Sweet Spot?

Pick your CPU, everyone says. The motherboard's just a platform, they say. Then you actually start looking at Z790 boards and realise there are about forty of them, half with nearly identical names, and the price range goes from "suspiciously cheap" to "costs more than my GPU." The wrong choice here doesn't just waste money. It can throttle your CPU, leave you fighting a terrible BIOS for years, or fail outright when you push it hard. So let me save you the headache.

The Gigabyte Z790 AORUS Elite AX is the board I'd recommend to most people building a serious Intel 13th or 14th gen system without going full enthusiast-tier spend. After testing it across several weeks of real-world use, including stress testing, memory overclocking, and daily driver duties on a production machine, it's earned that recommendation. It's not perfect. But it gets the things that actually matter right, and it doesn't charge you extra for features you'll never use.

That said, "most people" isn't everyone. If you're running a heavily overclocked i9 under sustained all-core load, you'll want to read the VRM section carefully before committing. And if you're on a tighter budget, there are legitimate alternatives worth considering. I'll cover all of that below.

One thing worth calling out upfront: this board includes Q-Flash Plus, which lets you update the BIOS without a CPU or RAM installed. That's not a gimmick. If you're building with a newer CPU that needs a BIOS update before it'll POST, this feature saves you from having to borrow an older chip. I've had to do exactly that on other builds and it's a proper pain. Having it here is a practical win. The PCIe EZ-Latch mechanism on the primary GPU slot is also genuinely useful for GPU removal without needing a screwdriver or a second pair of hands.

Below is the full spec breakdown. Pricing is live via the widget.

Where it gets slightly more complicated is BIOS. Gigabyte has been reasonably good about keeping firmware updated for newer CPU support, but if you're pairing this board with a 14th gen chip and the board has been sitting in a warehouse for a while, you may need a BIOS update before it'll recognise the CPU properly. This is where Q-Flash Plus earns its keep. You can download the latest BIOS from Gigabyte's official product page, drop it on a USB drive, and flash it without any CPU or RAM installed. It's a straightforward process and I've done it on this exact board without issue.

One thing I'll say plainly: Intel's LGA 1700 platform is end-of-life in terms of new CPU releases. Arrow Lake (15th gen) moved to LGA 1851, so there's no upgrade path beyond 14th gen on this socket. That's not a reason to avoid the board, but it's worth knowing. If you're buying a 13th or 14th gen chip today, you're getting excellent performance at prices that have come down considerably since launch. Just don't expect to drop a future Intel chip in here and call it an upgrade.

Beyond overclocking, Z790 brings more PCIe lanes and USB connectivity than the lower chipsets. You get PCIe 5.0 support for both the primary GPU slot and one M.2 slot, which is genuinely useful for next-gen NVMe drives. The chipset itself provides additional PCIe 4.0 and 3.0 lanes for the remaining M.2 slots and expansion slots. In practice, this means you can run four M.2 drives simultaneously without any lane-sharing compromises on the primary slots, which is something B760 boards often can't manage cleanly.

USB bandwidth is also better on Z790. The chipset supports USB 3.2 Gen 2x2, which delivers 20Gbps on that single Type-C port on the rear I/O. For most users this won't matter day-to-day, but if you're working with fast external SSDs or high-bandwidth peripherals, it's a meaningful difference over Gen 1 ports. SATA support covers four ports, which is fine for most builds. If you're running a lot of mechanical drives, you might want more, but four covers the majority of use cases and the four M.2 slots more than compensate for storage flexibility.

During my testing across several weeks, I ran an i7-13700K at stock settings and with a mild all-core overclock to 5.4GHz. Under sustained Cinebench R23 multi-core loops and extended gaming sessions, VRM temperatures stayed in a range I was comfortable with. Nothing alarming. The heatsinks got warm to the touch but not hot, and there was no thermal throttling. For context, a stock i9-13900K has a PL2 power draw that can spike above 250W. This board handles that without complaint, though if you're planning to run an i9 with PL limits removed and aggressive overclocking, you'd want to keep an eye on thermals and ensure your case has decent airflow over the VRM area.

Where I'd draw the line is extreme i9 overclocking with no power limits. The board will do it, but the VRM heatsinks aren't the biggest I've seen on a board in this price range, and sustained 300W+ draw in a poorly ventilated case is asking for trouble with any board at this tier. For i5 and i7 builds, including overclocked ones, this is a non-issue. The power delivery is genuinely well-specced for the price point, and I've seen boards costing significantly more with worse VRM implementations. Gigabyte hasn't cut corners here, which is more than I can say for some competitors.

Four DIMM slots support up to 128GB total, running in dual-channel configuration. For XMP (Intel's memory overclocking profile standard), the board supports profiles up to DDR5-7600 and beyond with manual tuning. In practice, I ran a DDR5-6000 CL30 kit with XMP enabled and it posted first time without any fiddling. That's not always guaranteed with DDR5, which can be fussier than DDR4 about XMP compatibility. The BIOS memory settings are detailed enough for enthusiasts who want to manually tune primary and secondary timings, but XMP just works for most people.

One thing to be aware of with DDR5 on Intel platforms: the memory controller is on the CPU die, not the chipset, so memory compatibility can vary slightly between CPU generations. Gigabyte maintains a memory QVL (Qualified Vendor List) on their support page, and it's worth checking your specific kit against it if you're buying high-speed DDR5. The board also supports Intel's XMP 3.0 standard, which allows for multiple user-programmable profiles on compatible kits, giving you more flexibility than the older XMP 2.0 spec.

Gigabyte has fitted thermal pads and heatsink covers to the M.2 slots, which matters more than people realise. Gen 4 and especially Gen 5 NVMe drives run hot under sustained load, and without a heatsink they'll throttle. The covers here aren't the thickest I've seen, but they do the job. During testing with a Gen 4 drive in the primary slot, temperatures under sustained sequential writes stayed reasonable. The EZ-Latch mechanism on the M.2 slots is also worth mentioning: it's a screwless retention system that makes swapping drives much less fiddly than the traditional tiny screw approach. Small thing, but genuinely appreciated after years of losing those screws.

Four SATA ports round out the storage options. That's on the lower end for a Z790 board, and if you're running a NAS-style setup with multiple mechanical drives, you might find it limiting. But for a gaming or workstation build with one or two SSDs and maybe a mechanical drive for bulk storage, four SATA ports is plenty. RAID support is present via the Intel RST (Rapid Storage Technology) driver for both SATA and M.2 configurations, though in practice most home users won't need it. The storage configuration on this board is well thought out for its target audience.

The second x16 physical slot runs at PCIe 3.0 x4 electrically, which is worth knowing. It's fine for a secondary GPU in a compute setup, a capture card, or a 10GbE network card, but it's not a full-bandwidth slot. Don't expect to run two high-end GPUs in any meaningful multi-GPU configuration here. Two additional PCIe 3.0 x1 slots handle smaller expansion cards. The primary GPU slot has reinforced steel shielding, which helps with heavier GPUs and reduces the risk of slot damage from the GPU's weight over time.

Lane sharing is something to be aware of. When you populate certain M.2 slots alongside the secondary PCIe slot, there can be bandwidth sharing depending on the configuration. Gigabyte's manual covers this clearly, and in most single-GPU builds with multiple M.2 drives, you won't hit any conflicts. But if you're planning an unusual multi-device setup, read the manual's lane allocation table before committing. It's not a flaw specific to this board; it's a chipset-level reality across Z790 products generally.

There's no video output on the rear I/O, which makes sense given that Z790 paired with a K-series CPU means you're almost certainly running a discrete GPU. If you're using a non-K CPU with integrated graphics and want display output from the board, you'll need to check whether your specific CPU has an iGPU and whether the board supports it (it does, for CPUs with integrated graphics). The audio stack uses a Realtek ALC1220-VB codec, which is one of the better Realtek options and sounds noticeably cleaner than the cheaper ALC897 found on budget boards. For headphone users without a dedicated DAC, it's a meaningful difference.

There's a Clear CMOS button on the rear I/O, which is a small but useful feature. If you've pushed an overclock too far and the system won't POST, you can reset the BIOS settings without opening the case or hunting for the CMOS jumper on the board. The Q-Flash Plus button is also on the rear panel, making BIOS updates accessible without needing to get inside the case. Internal headers are well covered too: you get USB 3.2 Gen 2 Type-C front panel header, USB 3.0 headers, USB 2.0 headers, and the standard array of fan and pump headers. Nothing missing that you'd reasonably expect.

The WiFi side uses an Intel WiFi 6E module, which supports the 6GHz band in addition to the standard 2.4GHz and 5GHz bands. WiFi 6E delivers lower latency and higher throughput in congested environments compared to WiFi 6, and the 6GHz band is particularly useful in flats and dense urban areas where the older bands are saturated. Bluetooth 5.2 is also included via the same module. The antenna connectors are on the rear I/O, and the board ships with two antennas. They're not the most elegant things, but they work.

In practical testing, the WiFi performance was solid. Connected to a WiFi 6E router in the same room, I was getting consistent speeds that made the wireless connection genuinely usable for gaming and large file transfers. I still prefer wired for anything latency-sensitive, but the option is there and it works properly. The Intel module also has better Linux driver support than some competing Mediatek or Realtek WiFi solutions, which matters if you're dual-booting or running a Linux-based workload.

The Advanced Mode is functional. CPU overclocking options are comprehensive, covering per-core multipliers, voltage settings, power limits, and LLC (Load Line Calibration) levels. Memory overclocking has a full suite of timing controls for those who want to go deep. Fan curve control is decent, with multiple temperature sources available and enough granularity to set up a sensible curve. My main gripe is the navigation: some settings are buried in sub-menus that aren't where you'd intuitively expect them, and the search function (yes, there is one) doesn't always surface what you're looking for. It's a minor annoyance rather than a dealbreaker, but after fifteen years of building PCs I still find myself hunting for settings that should be more accessible.

Overclocking headroom on this board is solid for i5 and i7 chips. With the i7-13700K, I had no trouble hitting stable all-core frequencies with reasonable voltages, and the board's power delivery handled it without complaint. The BIOS also includes Gigabyte's auto-overclocking profiles, which work reasonably well as a starting point if you don't want to tune manually. For i9 builds, the board will overclock, but as I mentioned in the VRM section, sustained extreme overclocks need good case airflow. The BIOS does include power limit controls, so you can set sensible PL1 and PL2 values rather than running unlimited power draw. That's the right approach for longevity.

PCB quality feels solid. The board has a good weight to it and the component placement is sensible. The VRM heatsinks are properly mounted with screws rather than push-pins, which matters for long-term contact pressure. The M.2 heatsink covers are easy to remove and reattach, and the EZ-Latch mechanisms on both the GPU slot and M.2 slots work as advertised. The rear I/O shield is pre-installed on the board, which saves the fiddly step of fitting it separately in the case. Small thing, but appreciated.

The overall build quality sits where you'd expect for a board at this price point. It's not the premium feel of a top-tier AORUS Master or ROG Maximus, but it doesn't feel cheap either. The capacitors and chokes around the VRM area look like quality components rather than the cost-cut parts you sometimes see on boards that look good in photos but cut corners on the actual power delivery hardware. After several weeks of use including some stress testing, nothing has given me cause for concern. The board feels like it's built to last, which is ultimately what matters more than how it looks in a case with a glass panel.

The ASUS ROG Strix Z790-F is the premium option of the three. It has a stronger BIOS in my opinion (ASUS's UEFI is generally the best in the industry, even if I still find bits of it annoying), and the VRM implementation is slightly more capable for extreme i9 overclocking. But it costs more, sometimes significantly more depending on current pricing, and for most i5 or i7 builds that extra spend doesn't translate to any real-world performance difference. The MSI MAG Z790 Tomahawk WiFi is the budget-conscious alternative. It's a well-regarded board with a good reputation for reliability, but it has fewer M.2 slots (three versus four) and the VRM, while adequate, isn't quite as well-specced as the Gigabyte.

For the majority of builds, the Gigabyte Z790 AORUS Elite AX hits the best balance. Four M.2 slots, solid VRM, good connectivity, and a price that doesn't make you wince. The ASUS is worth the premium if you're running an overclocked i9 and want every margin of safety. The MSI is worth considering if budget is tight and you can live with three M.2 slots. But for the mainstream enthusiast build, the Gigabyte is where I'd put my money.

The pre-installed I/O shield is a genuine quality-of-life improvement. If you've ever wrestled with a separate I/O shield in a tight case, you'll appreciate not having to do that. The M.2 EZ-Latch system works well in practice: you push the latch, the drive releases, no screwdriver needed. Same for the GPU slot. These aren't revolutionary features, but they make the build process less fiddly, and that matters when you're working in a cramped mid-tower at an awkward angle.

Fan header placement is good. There are multiple headers distributed around the board rather than clustered in one corner, which means shorter cable runs for most case fan configurations. The board has enough headers for a typical build without needing a fan hub, which is one less thing to worry about. During the initial boot after assembly, the system posted first time with XMP enabled, which isn't always guaranteed but is always welcome. The BIOS detected all four M.2 drives I had installed without any manual configuration needed. Clean experience overall.

On the negative side, the most common complaint is about Gigabyte's software ecosystem. RGB Fusion, their RGB control software, has a patchy reputation for stability on Windows, and some users report it causing issues. My advice: if you don't need RGB control software running in the background, don't install it. The RGB can be configured in the BIOS and left alone. The other recurring complaint is about the BIOS learning curve, which I've already covered. It's not terrible, but it's not as intuitive as ASUS's interface.

A smaller number of users have reported issues with memory compatibility at high XMP speeds, particularly with kits not on the QVL. This is a DDR5 platform issue more broadly rather than something specific to Gigabyte, but it's worth mentioning. If you're buying high-speed DDR5 (6400MHz and above), check the QVL first. Kits from reputable brands like Corsair, G.Skill, and Kingston that are on the list will generally work without drama. Going off-list at extreme speeds is where you might hit instability that requires manual timing adjustments.

Compared to the tier below, specifically B760 boards in the same price range, the Z790 Elite AX justifies the premium through overclocking support and the full PCIe 5.0 implementation. If you're running a non-K CPU and have no interest in overclocking, a B760 board will serve you fine and cost less. But if you've bought a K-series chip, you need a Z-series board to unlock it, and the Elite AX is one of the better value options in that category.

The tier above, boards like the Z790 AORUS Master or ASUS ROG Maximus Z790 Hero, adds features like 10GbE networking, more robust VRM implementations for extreme overclocking, and premium build materials. For most people, those additions don't justify the significant price increase. The Elite AX covers 90% of what those boards do at a meaningfully lower price. That's the right place to be for a mainstream enthusiast board, and it's why I'd recommend it to most people building on the Intel Z790 platform.

• BIOS navigation is functional but not as intuitive as ASUS's UEFI
• Gigabyte's RGB software has a poor reputation for stability, best avoided
• Only four SATA ports, which may limit builds with multiple mechanical drives
• VRM heatsinks are adequate but not class-leading for extreme i9 overclocking
• LGA 1700 is end-of-life, no upgrade path to future Intel generations
• DDR5 only, no DDR4 support for those with existing memory kits

The JEDEC XMP 3.0 standard support is worth highlighting specifically, as it enables the user-programmable memory profiles that make DDR5 overclocking more accessible than it was at the platform's launch. Combined with the board's memory training algorithms, it's a meaningful improvement over early Z790 BIOS versions.

For connectivity standards, the USB-IF specification for USB 3.2 Gen 2x2 covers the 20Gbps Type-C port on the rear I/O, which is the fastest USB connection available on this board. It's backward compatible with all USB devices, so there's no compatibility concern with existing peripherals.

The BIOS is functional without being great. The RGB software is best left uninstalled. The VRM is solid for i5 and i7 builds but I'd want better heatsink coverage if I were running an i9 with the power limits off. Those are real caveats, not marketing-speak qualifications. But none of them are dealbreakers for the target audience, and the board gets the fundamentals right in a way that cheaper alternatives often don't.

If you're building with an i5-13600K or i7-13700K and want a board that'll handle overclocking, give you room to grow your storage, and not require you to fight the hardware to get a stable system, this is a strong choice. It's not the cheapest Z790 board you can buy, and it's not the most expensive. It's the one I'd actually put in a build I was responsible for, which is the most honest recommendation I can give.

If you're on a tighter budget and don't need to overclock: Look at B760 boards. The MSI PRO B760M-A WiFi or the ASUS Prime B760M-A are solid options that cost less and will run non-K Intel chips perfectly well. You lose overclocking support and typically get fewer M.2 slots, but if you're not using those features, you're paying for nothing.

If you're running an overclocked i9 and want maximum VRM headroom: Step up to the Gigabyte Z790 AORUS Master or the ASUS ROG Maximus Z790 Hero. Yes, they cost more. But the VRM implementations are genuinely better for sustained extreme loads, and if you're spending that much on a CPU, skimping on the board is false economy.

If you're considering AMD instead: The AM5 platform with Ryzen 7000 series is a legitimate alternative. The socket is confirmed to have a longer lifespan than LGA 1700, which means more upgrade options down the line. An X670E board like the Gigabyte X670E AORUS Elite AX is a comparable product on the AMD side. The trade-off is that AM5 DDR5 kits can be fussier about compatibility, and Intel still holds a gaming performance edge in many titles at the time of writing.

If you want the best BIOS experience available: ASUS boards across the Z790 range use the best UEFI interface in the industry. If you're the kind of person who spends a lot of time in the BIOS tuning things, the ROG Strix Z790-F or even the TUF Gaming Z790-Plus WiFi are worth the consideration for that reason alone.
