The SteelSeries Apex 9 continues the very popular SteelSeries Apex lineup. This keyboard uses proprietary linear OptiPoint switches, which have two fixed preset actuation points: one for gaming and a slightly longer one for typing. Although these OptiPoint switches don't have the same range as the OmniPoint switches found on the SteelSeries Apex Pro, they still add versatility to what would otherwise be a high-performing TenKeyLess gaming unit. As a departure from the other keyboards in this lineup, the Apex 9 is hot-swappable; however, your switch options are limited to other single-pin optical switches only.
Our Verdict
The SteelSeries Apex 9 is a remarkable gaming keyboard. It has split millisecond latency and a super light actuation force along with a specific "gaming setting" that sets the actuation point at 1.0mm, so keypresses feel very responsive and fluid. You can program macros to any key and customize the RGB backlighting. Overall, it feels well-built, and while it's pretty comfortable to use, it could benefit from the use of a wrist rest, which you'll have to purchase separately.

Since the SteelSeries Apex 9 is a wired-only keyboard that uses a USB-A to USB-C cable, it isn't recommended for use with mobile devices and tablets.
The SteelSeries Apex 9 is a very good keyboard for programming. Overall, it feels very well-built with premium materials used in its construction. It offers a nice typing experience with fully backlit keys. You can program macros to any key without using the companion software, which is great as SteelSeries GG isn't available on Linux. Since the unit is wired-only, it isn't suitable for use in multi-device setups. Also, it lacks an included wrist rest, which would improve the overall comfort during use.

The SteelSeries Apex 9 is a poor keyboard for use with home theater or entertainment setups. It's wired-only, meaning you'd have to run a cable from the keyboard to your device, and it lacks a trackpad or trackball for on-screen navigation. That said, it's very solidly built, so it would sit well on your lap without flexing, and its backlighting makes your key legends easy to read in the dark.

Differences Between Sizes And Variants
The SteelSeries Apex 9 comes in one colorway, black, but there are many different language options available. There's also a smaller variant called the Apex 9 Mini. We bought and tested the TenKeyLess US English version, and you can see the label on our unit here.
Compared To Other Keyboards
The SteelSeries Apex 9 continues the SteelSeries Apex lineup of gaming keyboards. The main difference between this unit and the others in this lineup is the use of proprietary OptiPoint switches. Rather than the magnetic OmniPoint switches found in the Apex Pro editions, or the standard mechanical switches found in the SteelSeries Apex 7 TKL, these OptiPoint switches are optical switches that use lasers to register a keypress. Because of these switches, you can select the actuation point from one of two presets: 1.0mm for gaming and 1.5mm for typing. The gaming preset optimizes sensitivity, so your games feel responsive, while the typing preset is a bit longer to help you avoid registering accidental clicks. Although this feature is great for making this standard gaming unit more versatile, you'll likely find the 1.5mm Typing preset a bit too sensitive for regular tasks.

The SteelSeries Apex Pro and the SteelSeries Apex 9 are both premium gaming keyboards. The major difference is that the Apex Pro uses OmniPoint switches, which allow you to adjust the pre-travel distance within a range of points. The Apex 9, on the other hand, uses OptiPoint switches, which only have two preset actuation points, so you don't have the same degree of customization.
The SteelSeries Apex 9 and the SteelSeries Apex Pro TKL (2023) are TenKeyLess mechanical gaming keyboards with switches that allow you to adjust the auction point of individual keys. The Apex 9 uses OptiPoint switches that offer only two actuation point settings. On the other hand, the Apex Pro TKL (2023) uses OmniPoint switches which let you adjust the actuation point more precisely by increments of 0.1mm within a wider range. It also has an OLED screen and an included wrist rest, both of which the Apex 9 lacks.
The SteelSeries Apex 7 TKL and the SteelSeries Apex 9 are both TenKeyLess gaming keyboards with some fundamental differences. The Apex 7 uses standard mechanical switches, which come in your choice of clicky Blue, tactile Brown, and linear Red, while the Apex 9 uses specialized OptiPoint switches, which have two actuation point presets available, one for gaming and one for typing. That said, the Apex 9 is a much higher-performing gaming option with lower latency.
The SteelSeries Apex Pro Mini and the SteelSeries Apex 9 are both premium gaming keyboards. The major difference between the two is that the Apex Pro Mini uses OmniPoint 2.0 switches, which allow you to adjust the pre-travel distance within a wide range, while the Apex 9 uses OptiPoint switches which have two fixed presets for your pre-travel distance. Otherwise, the two keyboards offer similar incredible performance with very low latency.
The SteelSeries Apex 3 TKL and the SteelSeries Apex 9 are both wired-only TenKeyLess gaming keyboards. The Apex 9 performs much better overall as it has very low latency and very sensitive mechanical switches. The Apex 3 TKL uses rubber dome switches, which feel mushier and not as satisfying, and its latency is significantly worse.
The ROCCAT Vulcan II and the SteelSeries Apex 9 are wired mechanical gaming keyboards. The ROCCAT boards are available in a full-size or compact (65%) form factor, with linear Red or tactile Brown ROCCAT Titan II Optical switches. On the other hand, the SteelSeries boards are available in a TKL (80%) or Compact 60% form factors and use OptiPoint optical switches. These keyboards have higher-quality keycaps and better build quality overall. They also have lower latency, though both the ROCCAT and SteelSeries keyboards offer exceptional gaming performance.
Test Results
The SteelSeries Apex 9 is a TenKeyLess keyboard, so it has a smaller desk footprint, giving you more room for mouse movements while gaming.
The SteelSeries Apex 9 has excellent build quality. The chassis is made of hard plastic that exhibits only the slightest amount of flex, but overall this won't be noticeable during regular use. The baseplate is a lightweight aluminum alloy that adds great rigidity to the board. The doubleshot PBT keycaps feel great on the fingertips as they're stiff and have a nice rough texture. While the keys feel mostly stable, the space bar does have a bit of rattle, and the right shift button is wobbly. On the bottom of the keyboard, the six rubber feet do a good job keeping the keyboard in place. There's also a rubber foot on the end of each incline stand; however, these are a lot less grippy and tend to slide on the desk.
The SteelSeries Apex 9 has okay ergonomics. It's a straight profile board with two incline settings, though the maximum incline setting could feel a bit too angled, especially during a long typing session. This keyboard would benefit from a wrist rest, which you'll have to purchase separately.
While the PCB is technically hot-swappable, it's only compatible with OptiPoint Optical switches. That said, SteelSeries does sell replacements on their website.
The PCB has north-facing LEDs, and the switches are installed north-facing out of the box. Due to this north-facing orientation, there is a possibility of interference with some aftermarket sets of Cherry MX profile keycaps. While you can rotate the switches 180 degrees into a south-facing orientation, this significantly impacts backlight clarity for the shine-through keycaps, can affect actuation accuracy, and may potentially damage the PCB, so we don't recommend it.
The SteelSeries Apex 9 has individually backlit keys that are fully customizable using the companion software. The key legends are easy to read in the dark as they're shine-through. Unfortunately, the color mixing is pretty poor, as the white backlighting has a strong aqua hue to it.
The SteelSeries Apex 9 comes with a detachable braided USB-A to USB-C cable. It's longer than most cables by a few inches, but it's also quite stiff and retains kinks from the packaging.
The SteelSeries Apex 9 is a wired-only keyboard.
The SteelSeries Apex 9 has a few extra features. On the top right corner of the board, there's a volume wheel and a single button with multiple media control functions depending on how many times you press it. However, the most notable feature of this keyboard is the adjustable actuation point. Unlike the SteelSeries Apex Pro, the Apex 9 only has two available actuation point settings rather than a whole range. You can set the point to 1.0mm for gaming and 1.5mm for typing. There's a feature to set multiple inputs to a single keypress: one input upon pressing the key down and one input upon releasing the key. You can also record macros directly onboard using the macro programming hotkey. Additionally, this keyboard is hot-swappable, but you can only change the stock switches out for other single-pin optical switches.
The SteelSeries Apex 9 offers a great typing experience. The PBT keycaps have a good texture with nice grip, so you aren't prone to slipping off the keys as you type. While most of the alphanumeric keys are stable, there's a bit of wobbliness on some of the larger modifier keys. This wobble is due to the very light actuation force of the switches, which make them feel a bit unstable, although they're good for preventing finger fatigue. Overall, the layout isn't cramped, and you won't have a problem using this board right out of the box. The wrist posture is a bit strained, so you'd improve the overall comfort with a wrist rest, but you'll have to purchase one separately.
The SteelSeries Apex 9 is fairly quiet to type on. The OptiPoint switches have a linear feel with no click, but since they're very easy to bottom out, it does mean typing sounds a bit louder.
The SteelSeries Apex 9 uses proprietary linear OptiPoint Optical switches. These switches differ from the OmniPoint switches found in the SteelSeries Apex Pro boards since the OptiPoint switches use lasers rather than magnets. These switches have an adjustable pre-travel distance; however, instead of a whole range, you have the option of two actuation point settings: 1.0mm for gaming and 1.5mm for typing. Regardless of what setting you pick, the typing has the same feather-light actuation force, meaning you won't feel finger fatigue throughout the day. That said, typing might feel very sensitive at first because of this light actuation force.
This keyboard has exceptionally low latency. While you may expect a difference between the typing mode and gaming mode, there is no difference as testing with each mode yielded the same result.
The SteelSeries Apex 9 uses SteelSeries GG software for customization. This software is fairly straightforward to use and allows you to easily set macros, control the RGB lighting, remap keys, and create profiles. You can save all of these settings very easily to the onboard memory.
The score of this test box is based solely on the companion software's features and not its overall performance. We didn't experience any issues during testing. However, community members have identified a range of issues with this software.
The SteelSeries Apex 9 is fully compatible with Windows, macOS, and Linux. The software, however, is only available on Windows and macOS.

I eagerly await the results! I have question about test bench 1.3, how come single key release latency isn’t tested, but it is tested for multi key?
Hi,
Great question! Simple answer is, to avoid overloading the reviews with numbers.
The single key aims to show the keyboard’s best possible performance. So we focus on a single key, reduce the amount of “variables” that can impact the test.
Multi key aims to put that performance in the context of a heavy gaming scenario, or rhythm game (RG). For RGs the release timing can be really important so we decided to put the key release here.
During our testing key release was less sensitive to the total number of keys pressed so our results should be comparable to the expected release performance of a single key.

Request for Test Bench 1.3, to see the key release speed! Also how come there is no single key release speed?
