How much power do you need for esports? Last I checked, some players were gaming at 1080p or less, but Asus’ esports machine is packed to the gills with up to an Intel Core i9-9900K CPU and Nvidia GeForce RTX 2080 graphics card. So sure, this thing is branded for competitive gaming, but it’s a powerhouse you can use for just about anything. That is, if you can afford it ($3,299.99 / £2,499 to start, $3,799.99 / £2,999 as tested). For that price, however, you get some of the best pack-in peripherals we’ve ever seen.


The Strix GL12CX shares looks with its predecessor, the Asus ROG Strix GL12CM that we reviewed earlier this year. That means you get a dark gray, aggressively angular design and lots of RGB. The very front of the case has a bunch of stripes and angles and a magnetic front plate that pops off to reveal a neat trick: a hot-swappable SSD bay (there’s also an optical drive, but that’s far less innovative). Additionally, there’s a glowing ROG logo and an RGB stripe cutting across the front, which can be changed with Asus’ software.

Both sides are the same dark gray color, but the desktop comes with a transparent plastic panel for showing off your PC’s innards. It requires putting in some riser screws that allow for airflow before using hand screws to secure the panel. Note, there’s a small slogan on the clear panel: “Concealed in darkness, lethal in battle.” That comes off as goofy to me, even for a desktop with this aggressive design.

The GL12CX measures 18 x 15.7 x 7 inches (457.2 x 398.8 x 177.8mm), so it’s larger than other desktops with these beefed-up specs, like MSI’s Trident X, which is petite in comparison at 15.6 x 15 x 5.1 inches (396.2 x 381 x 129.5mm).

Ports and Upgradability

I can’t help but appreciate how many ports are easily accessible on the front of the GL12CX: two USB 3.1 Gen 1 (Type-A) ports, a pair of USB 2.0 ports, an SD card reader and a headphone jack are all available without reaching behind your machine.

Of course, there’s plenty more on the back, including pairs of USB 2.0 and USB 3.1 Gen 1 (Type-A), as well as four USB 3.1 Gen 2 (Type-A) ports. Additionally, there’s an Ethernet jack, and one port each for S/PDIF out, mic in, line out and subwoofer. All of the video ports are on the GPU: two DisplayPorts, an HDMI output and VirtualLink for VR headsets.

Removing each side panel requires taking out two Philips head screws, as opposed to the easier thumb screws of many competing systems. The GPU is held in with a crossbar for support, but if you want to upgrade (I suppose when the RTX 3080 comes out?), that’s simple to do. The two sticks of RAM are immediately accessible, as is a DIMM.2 drive, which plugs into an extra slot next to the RAM. It fits two M.2 SSDs, though ours had just one 512GB SSD in it.

The 5.25-inch bay for the 1TB, 7,200-rpm HDD is in the back. Accessing it requires taking off the left side panel. The cable management is pretty intense back there, and the HDD is surrounded by cords. You could remove a few cable ties to get to it, but you may have a mess putting the whole thing back together.

On the bright side, there is the hot-swappable SSD bay. Simply take a magnetic cover off the front of the desktop and pull out the tray to upgrade your SSD.

Gaming, Graphics and VR

Unsurprisingly, the Nvidia GeForce RTX 2080 with 8GB of GDDR6 can tear through games. When I played Call of Duty: Black Ops 4s battle royale mode, Blackout, in 4K with all of the settings on high, it ran between 47 and 55 frames per second (fps). At 1080p, It ran between 144 and 155 fps.

On the Hitman benchmark (1920 x 1080, ultra), the GL12CX ran the game at 139 fps, just below the Trident but higher than the desktop average. At 4K, it ran the game at 73 fps, again just a few frames behind MSI’s machine.

The Shadow of the Tomb Raider benchmark on the highest presets is tougher. The GL12CX ran the game at 77 fps at 1080p, while the Trident reached 89 fps. At 4K, the GL12CX fell under the 30-fps playability threshold at 27 fps, but the Trident just made it.

Both the GL12CX and the Trident crushed Grand Theft Auto V at 1080p and very high settings at 102 and 105 fps, respectively. But at 4K, the GL12CX clunked along at 28 fps, though the Trident hit a playable 35 fps.

On the SteamVR performance test, both desktops reached a perfect 11, making it Oculus Rift or HTC Vive ready.

To stress test the machine, we ran our Metro: Last Last benchmark 10 times on a loop. The average frame rate was 92.9 fps. There was some definite variance, with runs skipping between 85 fps and 95.8 fps before stabilizing between 92 and 94 fps. The CPU ran at an average of 4.4GHz and 53.1 degrees Celsius (127.6 degrees Fahrenheit). The GPU’s average temperature was 73.8 degrees Celsius (164.8 degrees Fahrenheit).


With an Intel Core i9-9900K, 16GB of DDR4 RAM, a 2TB, 7,200-rpm HDD and 512GB PCIe SSD, the GL12CX is no slouch. It powered through my average workday and simple tasks, like word processing and photo editing.

On Geekbench 4, the GL12CX earned a score of 31,016, just behind the MSI Trident X (31,581) but far beyond our gaming desktop average (19,955).

The GL12CX copied 4.97GB of files in 7 seconds for a rate of 757MBps, which is faster than the Trident (424MBps) and 367.5MBps average.

It took 24 seconds for the GL12CX to pair 65,000 names and addresses in our Excel macro test, coming out a second ahead of the Trident and far ahead of the average.

On our Handbrake test, in which we use the program to transcode a 4K video to 1080p, it took the GL12CX 5 minutes and 1 second to complete the task. That’s 37 seconds faster than the Trident X and the average of 6:43.

Keyboard and Mouse

These are the best pack-in peripherals I’ve seen on a gaming desktop. That may be because these aren’t just cheap add-ons, but an actual mouse and keyboard that Asus sells separately.

The mouse, the ROG Gladius II Origin, is a wired FPS gaming mouse with a 12,000-DPI optical sensor and Omron switches that should last for up to 50 million clicks. The rubbery grip is far more comfortable than most plastic mice tossed in with gaming notebooks.

The keyboard, the ROG Strix Flare, has Cherry MX red switches and media controls aligned to the left so that they are closer to your hand on the WASD keys. There’s also a USB passthrough, and a wrist rest, while plastic, is still welcome.

Both of the peripherals are compatible with Asus’ Aura Sync RGB lighting platform, and you can synchronize them with the desktop in whatever patterns or colors you choose.

Software and Warranty

Asus actually took it easy on the pre-installed software with the GL12CX.

That’s partially because it bundled in a bunch of features into one new app: Armoury Crate (yes, with a “u” in proper, British English). It serves as a hub that shows your CPU and GPU loads, memory and storage and fan speeds along with different usage modes that adjust the overclocking.The app also lets you stop select processes while you’re playing games. It’s also the new home for Aura Sync, so you can use it to select RGB colors and choose which devices should be synchronized. Like Asus’ old software, it can be used to launch other Asus apps, like Sonic Studio 3 and Sonic Radar for audio, XSplit Gamecaster for streaming and Game First to adjust which programs get network priority.

Still, Asus has some junk on there, including a McAfee Security trial, Asus Five-in-a-Row and setup apps for both Asus’ Windows Mixed Reality Headset and the Oculus Rift. And that’s on top of all of the questionable extras packed into every Windows 10 installation.

Asus sells the ROG GL12CX with a one-year warranty.


Our review config costs $3,799 (£2,999) with an overclocked Intel Core i9-9900K CPU, Nvidia GeForce RTX 2080 with 8GB of VRAM, 16GB of RAM, 512GB of M.2 PCIe-NVMe SSD storage and a 2TB, 7,200-rpm HDD.

For $3,299.99, you bump down to an overclocked Core i7-9700K CPU and a smaller, 256GB SSD. In the UK, there will be a version for £2,499 withi a Core i7-9700 CPU,  128GB SSD, 1TB HDD and 16GB RAM.

If you’re looking for something cheaper, try the $1,449 Asus ROG Strix GL12, which has the same chassis and hot-swappable SSD bay but lesser specs with an Intel Core i7-8700K, 8GB of RAM, a 256GB M.2 SATA SSD, a 1TB, 7,200-rpm HDD and an Nvidia GeForce GTX 1060 (6GB). That can be upgraded to a GTX 1070 or GTX 1070 Ti for extra.

Bottom Line

Asus can call the ROG Strix GL12CX what it wants, but this is no esports machine. It’s way too powerful and expensive for that. It’s a powerhouse gaming rig designed to show games at their very best. It does have some esports benefits, like great peripherals, a lot of accessible ports and a hot-swappable SSD bay. But for nearly $4,000 (as our review unit was configured), we expected more.

If you don’t care about Aura Sync or the esports features, MSI’s Trident X is a better deal. It starts at $1,999 with a Core i7 and GTX 2070 and goes up to $2,499 for a similar rig to what we reviewed with a Core i9 and a GTX 2080. There are some definite savings there.

But if you’re in on Asus’ lighting ecosystem or want great peripherals packed in the box, the GL12CX is worth looking at. You’ll just pay a lot for it.

    $3,800 is a lot of money for this thing. Can I get the non-rgb version for $2500?
  • SgtScream
    Not it
  • gasaraki
    Why the hell is this $3800 US? That is why above the cost of the parts, labor and reasonable profit.
