GIGABYTE Z490 AORUS Master Motherboard Review

Introduction, Specifications, and Pricing

In anticipation of Z590 coming later this year, we are wrapping up our coverage of Z490 with two boards from GIGABYTE. On the bench today, the Z490 AORUS Master is the first and a board that lives just under the top tier AORUS Xtreme in GIGABYTE's gaming lineup.

Coming into the Z490 platform last year, A huge focus for vendors was to clean up VRM power designs to handle the new LGA1200 product stack as this generation would be the first to see HyperThreading from the Core i3-10100 to the Core i9-10900K. GIGABYTE has done this and more with an extreme VRM design, which we will touch on below, along with advanced thermal solutions with true fin stacks.

Specifications and Marketing

GIGABYTE Z490 AORUS Master Motherboard Review 02 | TweakTown.com


We kick off motherboard specifications starting with the Intel LGA1200 socket. This platform is compatible with an entire range of processors from 10th Gen Core i3 to Core i9. This board's power design is thoroughly overkill, even for the enthusiast overclocker, offering a doubled seven-phase design for the Vcore with Intersil ISL99390 stages at 90A each. SOC is powered by a single Vishay SIC651 50A stage and Intersil ISL69269 PWM controller behind it all.

3x PCIe 3.0 x16 slots handle expansion, the top slot being the only full x16 electrically. Storage starts with 6x SATAIII ports that give way to the Ultra m.2 storage configuration that includes three slots, all under the motherboard heat sink.

The Intel i225 handles LAN duties on this motherboard, with AX200 handling Wi-Fi. Audio design is one of the best we have seen ALC1220 with ESS Sabre for your DAC needs.


The Z490 AORUS Master carries an MSRP of $399.99 with a three-year warranty. Current pricing can be found below.

Final Thoughts

GIGABYTE has done an amazing job appealing to gamers with edgy motherboard design and superb build quality. On top of that, the AORUS Master offers what is likely the best power design I've seen on a Z490 platform with fourteen 90A power stages.

One of the biggest features often overlooked, or where corners are more often cut, even on high-end gaming motherboards, is rear I/O connectivity and most often USB ports. Gamers need USB, and most don't want to bother with hub and docks to extend this connectivity. AORUS Master delivers in this department with 10 USB ports on the rear I/O alone, another two through internal 2.0, and three more via 3.2 internal headers. Add to this that GIGABYTE is the first I've seen to offer dual Thunderbolt 3 headers, which makes this board a straight-up beast for connectivity options!

What We Like

VRM Design: Over 1300A of pure VRM power for your CPU!

Connectivity: 15 USB Ports, 3x m.2 and 4x Thunderbolt 3 if you so choose makes this board a king of connectivity.

What Could Be Better

LAN: Won't lie, I would have liked to see something better than the Intel i225-V on this motherboard.

Price: All these features come at a price.

Buy at Amazon











The Bottom Line

The AORUS Master is a clear winner for gamers that want the ultimate in connectivity and overclocking prowess in their motherboard.

Asus Prime Z490-A

An ATX motherboard for Intel's 10th-Generation "Comet Lake-S" processors, Asus' Prime Z490-A sits apart from the company's ubiquitous Republic of Gamers (ROG) family of components and has a wholly different, less edgy look and feel—one meant to attract a more professional audience with a cooler aesthetic. Priced at $229.99, it also undercuts some of Asus' ROG boards. The Prime would work fine as the foundation for a new gaming PC, but this motherboard is also a fitting solution for shoppers who want to build or upgrade to a powerful productivity computer or a Core- rather than Xeon-based workstation.

The Board Design

The Prime Z490-A features a black PCB with white strips running across it. The rear I/O shield, as well as the chipset heatsink on this board, are also colored white. The bright, contrasting color on this otherwise dark component is eye-catching and draws your attention to these two areas on the board.

Asus Prime Z490-A overhead view

Other than that, the board isn't particularly decorative. The rear I/O panel and chipset heatsink are plainly adorned and not much to look at. This changes when you power up the system and RGB LEDs embedded in these two items illuminate, but even then the Z490-A has to be one of the least flashy premium boards I've reviewed lately.

That's not necessarily a bad thing, though. Some people don't want any extra flair inside their PCs, and I wouldn't mind seeing a few more boards like this tastefully reserved platform in the high-end market.

Asus Prime Z490-A diagonal view

Asus equips the Z490-A with a 12+2 DrMOS power design. The power-phase components are passively cooled by a trio of fairly large metal heatsinks that circle the LGA1200 CPU socket. These heatsinks sport a simple polished-metal finish. The shine adds to the board's aesthetic and gives the PCB a high-quality, industrial look.

Asus Prime Z490-A diagonal overhead

Storage support on this board consists of the usual six SATA 3.0 ports, along with two M.2 Key-M slots. One of these is hidden underneath a metal heat spreader to help keep any device you place here cool. The heat spreader is also lightly decorated with a few white accent stripes emblazoned over the same metal finish that we see on the other heatsinks.

A Brief Look at the Networking and Audio

In addition to the Key-M slots, the Prime Z490-A has a M.2 Key-E slot that can be used to add a wireless networking adapter, but it does not ship with Wi-Fi built into the board. It does feature a capable wired Ethernet controller, though. The Intel I225-V can support up to a 2.5Gbps Internet connection, which should be more than fast enough for the needs of most users.

Any techies want to take a guess what's driving audio on this board? If you said Realtek's S1220A, then congratulations, you're right! Nowadays, the majority of premium motherboards I see make use of this Realtek chip, and it's been that way for a while. Lower-end boards tend to use a wider selection of chips, but at the high end the Realtek S1220A audio codec is almost always what anchors the audio hardware. It's hard to fault motherboard OEMs for this, either—the S1220A is known to provide a fairly high signal-to-noise ratio, and it works without any major known issues.

Asus Prime Z490-A diagonal closeup

It's a case of OEMs not fixing what isn't broken. Nobody that wants a true Hi-Fi audio experience is going to settle for an integrated audio controller no matter how good it is. At the same time, a lot of people nowadays use S/PDIF or HDMI audio, both of which bypass the onboard DAC entirely. Overall, there isn't much need for a better audio controller than the S1220A, and tossing money at a more expensive one would be just a waste of resources that could be better spent elsewhere. The really audio-serious folks would just buy better dedicated hardware, anyway.

The Rear I/O Panel

The rear I/O panel on the Prime Z490-A is reasonably well stocked, with a total of seven USB Type-A ports. As most things connect through USB now, you can fairly well judge one of these panels based merely on the type and number of USB ports, and seven is a decent number. 

Two of these ports are legacy USB 2.0 ports, suited for a keyboard and mouse. The remaining five are all USB 3.2 ports, two of which are Gen 1 and three Gen 2. An eighth USB port on the rear I/O panel is a Type-C USB 3.2 Gen 2 port.

Asus Prime Z490-A rear I/O

Directly below the USB ports is the usual set of five 3.5mm audio jacks, as well as an S/PDIF port. You can also find an RJ-45 Ethernet jack beside the lower USB ports, and at the top of the rear I/O panel are an HDMI port and a DisplayPort connector for video output. These last two are key in the event that you mean to rely in any way on the onboard Intel UHD Graphics of any of the 10th-Generation chips. 

The Building Experience

Building up a system with the Prime Z490-A proved painless and straightforward. One of the biggest stressors when building any system is usually routing, stretching, and plugging in the CPU's power cable, but that's not a major problem here. The heatsinks covering the board's VRMs are big, but they are spaced far enough away from the CPU power connector to make getting the plug in place easy and painless—well, about as easy and painless as it gets. Calling the job of plugging in a CPU power connector on any system "easy" would be a bit of an overstatement. But I've experienced far worse.

The CPU fan headers are a bit more problematic, but you'll manage them. These two are offset from the VRM heatsinks to give you a small margin of clearance on all sides. If you use a water cooler with the radiator mounted at the top of your case, as I did for this build, then you will likely have the radiator partially obstructing your access to the fan headers. The experience here will vary widely, though, depending on your selection of CPU cooler and the dimensions of your particular chassis. In general, this placement of the headers is fairly common, and it's not terribly difficult to get the fans plugged in, but the placement could be a little better.

There's not much to say about plugging in video and add-on cards, as that's essentially the same on every ATX motherboard, so let's move on to storage. As mentioned above, you get two M.2 slots on this board. The lower of the two sits close to the right side of the board, directly below the chipset heatsink, which makes it relatively easy to access. PCI Express cards installed in the bottom two card slots shouldn't get in the way of adding an M.2 device here. If you are going for a multi-GPU setup, however, you will need to remove any graphics cards installed in the middle PCIe x16 slot in order to reach the screw holes for the M.2 slot.

Asus Prime Z490-A PCIe slots

The upper M.2 slot is covered by a heat spreader that is held on by two screws. As this is set directly below the primary PCI Express x16 slot, accessing this M.2 slot will be impossible with any graphics card installed. This isn't a flaw of the Prime Z490-A per se, as most motherboards that have M.2 slots place one of the slots here, nor does it prove to be a vexing issue in the long run. Just install your M.2 storage device before you build your system, and you'll be fine.

A Brief Look at the BIOS

The Asus Prime Z490-A comes equipped with a version of Asus' typical UEFI BIOS. Though a few things change from board to board, this BIOS should be readily familiar to anyone who has used a late-model Asus motherboard. 

Asus Prime Z490-A EZ Mode BIOS

Upon first entering the BIOS, we are greeted by an EZ Mode menu, which is a little lacking in my opinion. It displays all the info you need about your system configuration, and it has controls for setting the memory profile and adjusting the boot order. The major feature I found missing here is an option for flashing the BIOS to a new version.

Asus Prime Z490-A Main Tab BIOS

After entering the BIOS, you load into the Main tab, which displays core information on the motherboard itself, as well as the CPU and RAM. From here you can adjust the time and date, but that's about it. The My Favorites tab is significantly more useful, as it can be customized to create your own one-stop shop of settings for all your UEFI BIOS needs. Essentially any option available throughout the BIOS can be replicated on this tab, a super-useful feature in general for inveterate tweakers.

Asus Prime Z490-A Favorites BIOS

If you don't want to deal with the My Favorites tab, most BIOS functions can be adjusted through the Advanced tab. This tab is something of a catch-all for anything that doesn't fit in one of the other predefined sections of the BIOS. It's full of more functions than I could possibly discuss here without making this review a mile long to scroll through. The real enthusiast-minded fun is found in the AI Tweaker tab, so let's discuss that instead.

Asus Prime Z490-A AI Tweaker BIOS

The AI Tweaker tab houses all of the overclocking options on this board, with basic info shown at the top of this section. The main AI Tweaker page has few options, but you can activate the board's auto-overclocking feature from here and set memory profiles. You will find a few more options, such as multicore enhancements, but the fine-tuned controls are in subfolders under this menu. This was done to try to give you a more organized overclocking experience, with items such as DRAM timings, VRM controls, and CPU overclocking tools all separated out into their own designated folders.

The Utility Software

After I got Windows 10 booted up, installing drivers for the Asus Prime Z490-A proved a straightforward and easy process. All of the drivers installed just fine without the need to perform Windows 10 updates first. For some odd reason, though, Asus includes drivers on its support page for this board for a Wi-Fi controller and a Bluetooth device, though this board doesn't come with either of these preinstalled. Don't bother downloading those when you go to set up one of these boards yourself.

Asus Prime Z490-A ArmouryCrate

The Z490-A doesn't come with much in the way of software utilities, but the two that are here are useful. The first is Asus' ArmouryCrate app. It has controls for any RGB LEDs that are connected to the system, and it can be used to check for driver updates.

The other application is a free copy of Daemon Tools Lite. Technically, this software is always free, but the public free version has ads, and the version included with the Prime Z490-A doesn't, so that’s a plus. You will need to get Windows 10 updated before you will be able to install it, but once you do, you'll find Daemon Tools Lite to be a relatively useful application that can virtually mount disc images. It can also rip images from physical discs to store backup copies, and you can pay to upgrade it to burn discs, as well, if you want to.

Verdict: A Solid Z490 Starter for the Mid-Road Shopper

Judging products positioned like the Prime Z490-A can be difficult. After testing the Prime Z490-A and building a system around it, I can't find any complaints to make about the board. Everything works without issue, the BIOS is cleanly laid out and easy to use, and the overall feature set is competitive at its $229.99 price point. The board may look a little bland, with its lack of color, but some sober shoppers, weary of RGB excess, will find the monochrome look to be quite attractive and professional-looking.

Asus Prime Z490-A CPU socket

In spite of all these positive aspects, the board feels just a few strokes short of stardom. Take Asrock's Z490 Phantom Gaming Velocita, which is available for the same price and very competitive with the Prime Z490-A in terms of features. The Velocita has a substantially better thermal solution for the VRM heatsinks. It also has a second Ethernet jack and heat spreaders for both M.2 slots. The Prime Z490-A has advantages of its own, but if I had to choose between the two, I'd tip toward the Asrock. That's not to say that the Asus won't work perfectly fine as the main board in your new Intel LGA1200 PC, but it would be a more tempting solution if it were priced slightly lower.

Intel Z490 Motherboard VRM Temp Test, Sub $200 Roundup


NZXT is a company better known for cases, coolers and power supplies, but the company previously released a Z390 motherboard, and now it’s back with its first on Intel’s latest platform, the N7 Z490. Like the previous generation (N7 Z390), it’s adorned with all-metal covers hiding the PCB and all but the necessary slots, headers and buttons, akin to much-more expensive (even flagship class) motherboards. While the N7 matches NZXT’s cases really well, the black or white versions should fit in well with most build themes and other cases as well. Will NZXT’s offering find a place on our best motherboards list?

With an MSRP of $229.99, the N7 lands in the value-oriented Z490 realm, yet is still well-equipped. NZXT says it worked with ASRock as their vendor for the N7 Z490 to “...ensure we were able to create a motherboard that supports the newest generation of Intel’s CPUs with the proper connectivity and strong BIOS support,” and they have delivered on that front. The N7 includes premium Realtek audio, 2.5 Gb Ethernet, integrated AX200 Wi-Fi, and more. About the only thing it’s missing is integrated RGB lighting -- though it’s hard to see where it would go given the vast majority of the board is covered.

On the performance front, our review sample did well in most tests, and on the MS Office section in particular. It was a bit slower in Handbrake, adhering to Intel’s specifications a bit more closely on these longer-running multi-threaded loads. 3DMark and gaming performance was indistinguishable from the other Z490 models we’ve tested so far. Overclocking was a breeze, with the 10-phase VRM running our Intel Core i9-10900K at 5.2 GHz and memory at DDR4 4000 without issue.

In addition, the N7 Z490 sports dual M.2 sockets, four SATA ports, onboard power/reset buttons, and several 4-pin fan/pump headers. For those who are yearning for RGB lighting, the board includes multiple headers for standard RGB (3/4-pin) as well as two of NZXT’s headers. Below is a complete list of specifications from NZXT. Read on for details!

NZXT’s N7 Z490 comes with a few accessories to get the system up and running, including SATA cables, screws, and more. Below is a list of what is included in the box with the board.

  • User manual
  • Four SATA cables
  • WiFi antenna
  • Two M.2 screws

Taking a look at the N7 Z490 for the first time, it’s clear the vast majority of the board is covered with metal shrouds, leaving only slots, sockets, and headers exposed. The N7 is available with black or white shrouds, both with a flat matte finish. The covering above the VRM and chipset area are vented to help with cooling.

Image 1 of 2
Image 2 of 2

NZXT chose to forgo integrated RGB lighting, instead using two proprietary headers for NZXT devices, along with agnostic aRGB (3-pin) and RGB (4-pin) headers. Overall, the board matches well with NZXT’s H Series cases and would be a good fit for most build themes and chassis. If you like shrouds covering the PCB, the N7 has you covered -- literally. 

Focusing on the top half of the board, we get a closer look at all the shrouds that cover it. There is a cover for the IO area, and the two large VRM heatsinks form a clean right angle around the exposed socket area. Just above the VRMs is an 8-pin (required) and 4-pin (optional) EPS connector for sending power to the CPU.

Across the top, just above the VRMs, are the CPU and AIO/PUMP 4-pin headers. In total, the board has seven 4-pin fan headers, each capable of driving PWM and DC controlled fans. Output on all headers is listed at 12W/2A, which should be enough for most pumps and piggybacking a couple of fans on the same header. Fan control is handled through the BIOS or the company’s CAM software.

To the right of the socket area are four DIMM slots that lock the RAM down on one side. The N7 Z490 supports up to 128GB of RAM, with speeds listed to 4266(OC). While that supported speed is a bit lower than most high-end Z490 motherboards, unless you are benchmarking competitively, this shouldn’t be a concern.

Located just above and to the right of the memory slots are two NZXT RGB headers for using NZXT devices, along with two more 4-pin system fan headers. To the right of the RAM is a vertically oriented 24-pin ATX plug, delivering power to the motherboard, and the USB 3.2 Gen 2 Type-C header.

NZXT lists the N7 Z490 as a 10-phase (8+2) configuration. The EPS connectors send power to a Renesas ISL6269 PWM controller that feeds it to 50A Vishay SiC632A integrated MOSFETs for Vcore and SOC. The VRMs ran warmer than several other motherboards we’ve tested recently, but were well within operating specifications. While the 50A bits are not the most robust we’ve seen, the N7 Z490 handled our Intel Core i9-10900K at stock speeds and while overclocked without issue. 

The bottom half of the board is covered almost entirely, with only the headers across the bottom and the PCIe slots visible around the covers. On the far left is where the Realtek ALC1220 premium audio codec is hidden, along with Nichicon Fine Gold Series audio capacitors. Most users will find this solution sufficient for their needs.

In the middle of the board, popping out between the cover, are five PCIe slots: two full-length slots and three x1. The top full-length slot runs at x16 (CPU sourced) while the second full-length slot runs at a maximum of x4 (chipset sourced). This configuration allows for 2-Way AMD CrossfireX if you’re still into that sort of thing these days. For the x1 slots (chipset sourced), NZXT placed these well, with one above the primary (top) PCIe slot, and below the secondary slot. This configuration allows all three to be used when there is a single video card.

The two M.2 sockets are found hidden under removable covers just above the primary full-length PCIe slot and next to the two x1 slots on the bottom. Both sockets support up to 80mm modules, with the top slot running PCIe 3.0 x4 & SATA modes while the bottom slot is PCIe 3.0 x4 only. Just to the right of the chipset heatsink, again hidden under shrouds, are the four SATA ports (supporting RAID0, 1, 5 and 10) and a USB 3.2 Gen 1 port, all of which are angled horizontally for better cable management.

The bottom edge of the board is completely free of any covering, allowing easy access to all of the headers and buttons. Unlike the EVGA Z490 FTW, all headers are oriented vertically. Here we find audio/fan/USB headers and more. Below is a list of all the headers and buttons ordered from left to right.

  • Front panel audio
  • UART
  • 3-pin ARGB header
  • 4-pin RGB header
  • (3) USB 2.0 headers
  • (3) System fan headers
  • Clear CMOS jumper
  • Power/Reset buttons
  • Front panel header

The rear IO and its integrated IO plate have enough connectivity for most users, but may fall short on the USB side. In total there are six USB portsL two USB 2.0, two USB 3.2 Gen 1 ports and one each USB 3.2 Gen 2 Type-C and Type-A ports. Six USB ports are about the minimum most users would like to see, but if you need more, you’ll have to use an add on card to get them or use the front panel. Video output is handled by a single HDMI (v1.4b) port. Additionally, there are antenna mounts, a clear CMOS button, the LAN port, a 5-plug plus SPDIF audio stack, and a PS/2 port for ancient devices.
