The NuPhy Nos75 is a low-profile mechanical keyboard with a solid aluminum chassis and a gasket mount design. It uses Nano N1 switches, which are a new switch type produced in collaboration between Nuphy and Gateron. They use a standard Cherry pin layout and have a longer travel distance than most low-profile switches, offering a closer typing experience parallel with high-profile switches in a thinner form factor. This keyboard is also compatible with VIA software, allowing you to customize key assignments, adjust RGB lighting, and program custom profiles or record macros.
This keyboard has been discontinued. For more details, see the Differences Between Variants section.
Our Verdict
The NuPhy Nos75 is excellent for gaming. It has remarkable build quality with a solid aluminum case and a customizable mount design. Performance-wise, it delivers very low all-around latency, which is more than suitable for playing games in any genre at a casual or competitive level. You can also customize the RGB lighting along with other settings using the configuration software. Just note that, even at maximum brightness, the lighting is fairly dim. Additionally, the LEDs are South-facing, so legends aren't clearly visible in dark rooms with standard shine-through keycaps installed.

The NuPhy Nos75 is a wired-only keyboard that isn't suitable for use with tablets or mobile devices.
The NuPhy Nos75 is a very good keyboard for programming with remarkably good build quality. It has a customizable gasket-mount design and multiple layers of acoustic material inside the case that contribute to its excellent typing quality. Its compact 75% layout may not work for all workflows as it lacks some important keys from the navigation cluster. However, it also supports VIA software and QMK firmware, so you can remap keys as needed. Unfortunately, it's a wired-only model and while it has RGB lighting, the maximum brightness is quite dim. Additionally, the LEDs are South-facing, so legends aren't clearly visible in darker lighting with standard shine-through keycaps.

Differences Between Sizes And Variants
The NuPhy Nos75 has been discontinued several months after its release and is no longer available for purchase from NuPhy. During its production run, it was only available for purchase as a barebones kit in a wired configuration. It came with your choice of lubed or unlubed Gateron Nano N1 switches.
Keycap sets, extra weights, and plates in various materials were available for purchase separately. You can reference configuration options on NuPhy's product page, which remains live despite the discontinuation.
We bought and tested the NuPhy Nos75 with Gateron lubed N1 Nano switches. For an additional charge, we bundled a set of Space Engineer—Dark NSA keycaps from NuPhy's product page for our review.
Compared To Other Keyboards
The NuPhy Nos75 is a low-profile mechanical keyboard that ships in a barebones configuration bundled with Nano N1 (Gateron 3.0 low-profile) switches. These are noteworthy for using a standard Cherry-style pin-out design and for having a slightly longer total travel distance than most low-profile switches, providing a typing feel closer to a standard high-profile switch in a low-profile package.
This keyboard also offers a customizable hardware experience. It's easy to disassemble and includes several different options for gasket mounting to fine-tune the typing feel. During production, NuPhy offered several additional plate materials for additional purchase. In a blog post that details some of the development of this keyboard, NuPhy indicates that at one point, multiple switch types and additional colorways were planned for this keyboard but were scrapped due to market conditions.
Altogether, this keyboard presents a unique and much more premium alternative to other low-profile options such as the NuPhy Air75 V2, the LOFREE Flow, or the Keychron K3 Max. That said, its wired-only connectivity may be disappointing to some, and it will likely be very hard to find from third-party resellers now that it's been discontinued. That said, NuPhy has hinted on social media that they plan to release future keyboards with the newly developed Gateron 3.0 low-profile switches, so we may see NuPhy revisit this project in some form in the future.
For more recommendations, see our picks for the best keyboards, the best low-profile keyboards, and the best mechanical keyboards.
The NuPhy Air75 V2 and the NuPhy Nos75 are low-profile mechanical keyboards. On the one hand, the Air75 is a bit thinner. It also has wireless connectivity and offers several switch options at purchase. It also has both a slightly smaller 60% and slightly larger 96% variant available. The Nos75 is a slightly thicker wired-only model. It has a much more premium-feeling build quality with a solid aluminum case design and more of a focus on hardware customizability with several options for different gasket mount systems. It also has significantly better typing quality overall, but it's only compatible with the Gateron N1 Nano switches it comes with. Unfortunately, the Nos75 has been discontinued and is no longer available for purchase new from NuPhy.
The Keychron K5 Max and the NuPhy Nos75 are low-profile mechanical keyboards. The Keychron is part of a wide lineup of different-sized variants, while the Nos75 is only available as a compact 75% model. The Keychron is also a wireless model with a choice of switch types while the NuPhy is wired-only and only compatible with the Gateron N1 Nano switches it ships with. That said, it also has significantly more premium-feeling build quality and much better-typing quality overall. While both keyboards offer a high degree of hardware customization, only the NuPhy comes with a wide range of different mounting hardware so you can fine-tune your typing experience to your tastes. Unfortunately, the Nos75 is already discontinued and no longer available for purchase from NuPhy.
The Razer DeathStalker V2 Pro and the NuPhy Nos75 are both low-profile mechanical keyboards. The Razer is a full-size wireless model, while the NuPhy is a more compact, 75% wired-only keyboard. Both offer comparable gaming performance and feature full RGB lighting. However, the Razer comes with shine-through keycaps, while the NuPhy uses higher-quality PBT keycaps, though without shine-through legends. The NuPhy also boasts significantly better typing quality with Gateron Nano N1 switches and a noticeably more premium build, thanks to its solid aluminum case. Additionally, it offers greater hardware customizability, including various gasket mounting options.
The Corsair K100 AIR and the NuPhy Nos75 are low-profile mechanical keyboards. The Corsair is a thinner, full-size, wireless model designed specifically for gaming. It has a higher maximum polling rate of up to 8000Hz over a wired connection, offering better overall raw performance. It also uses Cherry MX Ultra Low Profile Tactile switches and has extra features such as dedicated media controls and shine-through legends, which the NuPhy lacks. Comparatively, the NuPhy is a bit thicker and has a more premium solid aluminum case. It offers a better overall typing experience and uses Nano N1 switches. Unfortunately, it's been discontinued and is no longer available for purchase new.
Test Results
This keyboard has a compact 75% layout with a fairly thin low-profile design. It has a dedicated set of arrow keys and a function row but it's missing a Numpad and has several fewer keys from the Navigation cluster.
Note that this keyboard comes in a barebones configuration without switches or keycaps. The measurements above are taken with switches and the keycaps (which we bought from NuPhy's Nos75 product page as an additional purchase) installed. See an image of the fully assembled keyboard.
The NuPhy Nos 75 has outstanding build quality. The case is made of solid aluminum and doesn't flex whatsoever. Note that this keyboard only comes in a barebones configuration. You need to install switches and keycaps yourself. The keys feel very stable while typing, and the keycaps (which we bought from NuPhy's Nos75 product page as an additional purchase) are made of high-quality doubleshot PBT plastic and have a pleasant, slightly textured finish.
The switches are pre-lubed from the factory and are very smooth and consistent. We noted that the stabilizers are very heavily lubed, which may contribute to some degree of inconsistency in feel between some of the larger keys, but we found this doesn't affect smoothness or stability, and we didn't experience any rattling or pinging sounds.
NuPhy refers to the single wraparound foot on the bottom of the keyboard as "GasFeet." It's a silicone piece filled with air and does a great job of keeping the board firmly in place while typing.
There's also a weight on the underside with an engraved logo. This weight is modular and can be replaced with the stainless steel PVD blue weight that was sold as an optional extra at purchase.
The NuPhy Nos75 has a fairly low-profile design. It's noticeably shorter than standard high-profile keyboards, such as the NuPhy Gem80, but not quite as thin as the NuPhy Air75 V2 or most other low-profile boards.
That said, it's comfortable to type on without a wrist rest, and you don't need to angle your wrists steeply to reach all the keys.
This keyboard offers outstanding hardware customizability. It comes with a CR-V Torx screwdriver and two bits (T8 and T6) to help you completely disassemble the board. We disassembled ours and found the process was very easy and straightforward. For reference, you can see a photo of the underside of the PBC here.
The LEDs are South-facing, which generally provides good visibility of the lighting effects when you're seated at your keyboard. However, this also limits the amount of light that will pass through most shine-through keycap sets, which are typically designed for North-facing LEDs. Additionally, this keyboard has 1u-sized right mod keys, which are slightly less common than the typical 1.25u size.
Technically, this keyboard has a hot-swappable PCB. The pin layout mirrors that of a standard Cherry-style 5-pinout design. However, standard high-profile 3- or 5-pin Cherry-MX switches won't properly seat in the sockets, which is expected.
It's possible that select low-profile switches designed for Cherry MX sockets may be pin-compatible with this keyboard, but we can't say for certain.
This keyboard has full RGB backlighting and individually lit keys. You can customize backlighting brightness and effects using the configuration software. Here's an image of the backlighting in the barebones configuration.
This keyboard has poor backlight clarity on legends as the keycaps (available on the product page for this keyboard for an additional purchase) lack shine-through legends, and the LEDs are South-facing.
We replaced some of the keycaps we purchased with low-profile keycaps with standard north-facing shine-through legends for reference.
NuPhy sells low-profile keycap sets with shine-through legends designed for better visibility and South-facing LEDs on their site.
With the RGB set to display white-only light at maximum brightness, we noted that the lighting is quite dim.
This keyboard comes with a USB-A to USB-C cable. It's made of fairly stiff rubber and has a coiled aviator-style section. The non-coiled segment retains some kinks from its packaging.
This keyboard lacks dedicated macro keys, and you can't record macros with keyboard shortcuts. That said, you can record macros to any key using the configuration software.
This keyboard has an indicator LED on the left side of the board (pictured above) that turns on when the Caps Lock is enabled.
You can toggle between OS compatibility modes with keyboard shortcuts: Fn+P for Mac and Fn+O for Windows.
For a list of other supported shortcuts, see an online version of the user manual.
Note: This keyboard comes as a barebones kit. It comes with switches that you need to install yourself, but keycaps are not included.

The NuPhy Nos 75 provides outstanding typing quality. The keys are very stable, and the keycaps (which we bought from NuPhy's Nos75 product page as an additional purchase) have an nSA profile that feels pleasant to the touch and has slightly concave tops that do a good job of keeping your fingers centered.
We noted some minor inconsistency in the feel of some of the larger keys which may be attributed to overlubing (see Build Quality), but this is a minor nitpick, and the stabilizers are very smooth overall without any rattling or pinging.
Several layers of acoustic and dampening material inside the case (image of the foam layers from NuPhy's website) help round out the sound profile. You can swap out or remove these layers to further customize your typing experience.
This keyboard uses what NuPhy calls an "Omni Mount," which provides some hardware customization for its mounting style.
By default, this keyboard comes with silicone sockets installed that give a slightly springy quality to typing.
Nuphy includes hardware that offers slightly different typing experiences, listed below
- 10x Silicone beans (Hardness 30)
- 10x Silicone beans (Hardness 70)
- 10x Silicone strips (Hardness 30)
- 10x Top mount hardware (Hardness 70)
- 4x Silicone Sock (Hardness 70)
There's a visual guide for choosing between mount styles on the keyboard's product page and a YouTube video guide for changing between mount styles.
This keyboard comes stock with an FR4 plate, which is fairly flexible and provides a less resonant, more neutral sound profile.
NuPhy also sold extra plates for this keyboard, which are made of aluminum, polycarbonate, carbon fiber, and POM. Aluminum plates are the stiffest of these options, but they're still fairly flexible compared to the steel plates in many prebuilt keyboards. Along with Carbon Fiber, they typically provide a somewhat higher-pitched sound profile. Polycarbonate and POM plates are a bit more flexible and tend to provide a deeper, more resonant sound signature.
The NuPhy Nos 75 is very quiet to type on and is unlikely to bother those around you, even in noise-sensitive environments.
This keyboard uses Gateron N1 Nano switches (which are also variously referred to as Gateron Low-Profile 3.0 switches in some of NuPhy's documentation). They have a POM plastic upper and lower housing and are pre-lubed from the factory.
While these switches have a standard 5-pin Cherry pinout design, the center stem has a slightly wider (4.2mm) diameter compared to a standard Cherry stem (3.7mm). Some users and other media outlets have reported that this may limit the compatibility of these switches on other keyboards. To our understanding, the Gateron Nano N1 switches likely aren't compatible with any other keyboard currently available.
The Gateron M1 Nano switches are lightweight linear switches. They're pre-lubed from the factory and feel very smooth and quite consistent. Despite being quite lightweight they have a fairly long pre-travel distance which can help minimize accidental inputs. These switches also have a fairly long travel distance compared to most low-profile switches. which can be particularly helpful for more forceful typists who may bottom out too forcefully on most low-profile switches.
The NuPhy Nos75 provides remarkable single-key latency performance making it very well suited for playing casual or competitive titles.
This keyboard provides excellent multi-key performance. It's well-suited for playing games that requires additional keystrokes while multiple keys are pressed and maintained.
This keyboard can send multiple keys per USB report and supports full N-key rollover by default out of the box. Its maximum polling rate is 1000Hz, and data transmission isn't bottlenecked by other latency components.
This keyboard has satisfactory chord split performance overall. However, it isn't particularly well-suited for playing competitive rhythm games or other titles that demand many simultaneous inputs.
To access the software, you need to download a .JSON file available on NuPhy's website. NuPhy also has a helpful guide to walk you through the process.
This software has a clean, easy-to-use interface. It allows you to control backlighting, customize key assignments, create custom layers and profiles, and record macros.
