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.
Remarkable build quality.
Excellent all-around latency performance.
1000Hz polling rate isn't bottlenecked by other latency elements.
South-facing LEDs offer poor backlight clarity for most shine-through keycap sets, making legends hard to read in the dark.
Discontinued. No longer available for purchase new.
The NuPhy Nos75 is good for office use. It has remarkable build quality with a solid aluminum case and a customizable mount design that allows you to fine-tune the stiffness of your typing experience. Its low-profile design is comfortable to type on without a wrist rest as you don't have to angle your wrists steeply to reach all the keys. It's also very quiet to type on and has multiple layers of acoustic material inside the case that help round out the sound profile. Unfortunately, it's a wired-only model that doesn't support multi-device pairing.
Remarkable build quality.
Quiet typing noise.
Outstanding typing quality.
Wired-only.

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.

The NuPhy Nos75 isn't designed for an entertainment or home theater setup. It's a fairly heavy wired-only model that has non-dedicated media controls. While it has RGB backlighting, the maximum brightness setting is fairly dim. The LEDs are also South-facing, so legends aren't clearly visible in dark rooms with standard shine-through keycaps installed.

The NuPhy Nos75 offers excellent raw performance with excellent single-key and great multi-key latency performance. It also has an effective update rate of 1000Hz that isn't bottlenecked by other latency elements. Altogether, it's more than suitable for casual or competitive gaming in nearly all genres. However, its chord split performance is only satisfactory, so it isn't a good match for playing competitive rhythm games or other titles that require many simultaneous inputs.

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.
Popular Keyboard Comparisons
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.
