Connectivity
Corsair K63
The keyboard comes with a long micro-USB charging cable and may be used wirelessly as well. The Corsair K63 Wireless can connect through USB or Bluetooth, allowing you to pair two devices at the same time. You may switch between them by pressing FN + F9/F10.
Corsair K65
The cable is sturdy and braided, although it will retain kinks from packaging. In the end, there are two USB ports, one for the USB passthrough and the other for the keyboard. This is a wired keyboard that will not work wirelessly.
Switches
Corsair K63
The linear Cherry MX Red switches on the keyboard are quiet. You should have no trouble using it in a quiet environment. The Corsair K63 Wireless Mechanical Gaming Keyboard has low latency. It has a minimal power draw when connected and is suitable when used with the receiver. However, it is not recommended for Bluetooth gaming.
On the Corsair K63 Wireless, the Cherry MX Red switches are standard. They need a certain amount of force to work, particularly linear switches, and they do not provide tactile feedback. Although the pre-travel distance is somewhat longer than the industry norm of 2mm, most consumers will not notice.
The linear switches are easy to operate, and the keys are dependable. Despite the fact that the key spacing is very standard, which may help with typing accuracy, there is no tactile feedback to indicate when a keypress has been registered. It’s really responsive, and typing for long periods of time doesn’t make you tired.
Corsair K65
Cherry MX Red switches are used in the Corsair K65 RGB. They take some effort to operate and have a long pre-travel distance. This can improve typing accuracy, but it can also make the keyboard seem less responsive, especially when gaming. Although the pre-travel distance exceeds the claimed 2.0mm, this might be due to manufacturing tolerances. Because the switches are linear and do not give tactile feedback, it may be difficult to tell whether a keypress has been registered.
The ABS plastic keycaps are smooth and a touch slippery, and they, unfortunately, have a shoddy feel about them. They are solid, and they do not wobble while typing, which is a benefit. The key placement is somewhat more spaced out than conventional spacing, which should not result in more mistakes but may create finger fatigue because you will need to extend your fingers further than usual. Despite this, you shouldn’t get too tired typing on this keyboard, especially if you utilize the wrist rest.
Feature Keys
Corsair K63
There are a few more features on this keyboard. Separate media control keys, a Windows lock key to protect your game from being accidentally minimized, and a backlighting brightness adjustment button are all included. Switching between connected devices (wireless USB or Bluetooth), putting the computer to sleep, and browsing Android-based mobile devices are all possible via hotkeys (back, home, overview, and search).
Corsair K65
The Corsair K65 LUX RGB has a few extra functions, like separate volume control and mute buttons, despite the fact that the majority of the media keys are hotkeys. A Windows Key lock button is located in the upper right corner of the screen to protect you from accidentally minimizing your game.
Design
On the Corsair K63 Wireless, each key is individually lighted, and the brightness can be changed right on the keyboard. It’s only available in one shade of blue, unfortunately. An Ice Blue variant is also available, which is a bit brighter.
The Corsair K63 Wireless Mechanical Gaming Keyboard has a small footprint and is tenkeyless (TKL). Because it features an extra row of dedicated media control keys, it’s a little bigger than comparable TKL keyboards, and if you use the wrist rest that comes with it, it’ll take up even more room. The build quality is decent.
The keycaps are ABS plastic, and the frame is composed of plastic that seems a touch flimsy. It has a similar appearance and feels as the Corsair K68 RGB, but the keys are more robust, and the wrist rest hooks are more durable.
The K65 is a TenKeyLess (TKL) keyboard that’s about the same size as the Corsair K63 Wireless Mechanical Keyboard. The build quality of the Corsair K65 is excellent. It features a brushed metal top plate that feels strong and doesn’t bend, and it has a plastic base.
The edges of the metal top plate, on the other hand, are rather sharp and can cut your skin. The ABS plastic keycaps have a great, smooth texture and don’t wobble when typing, but they have a cheap feel to them. There are four rubber feet beneath the keyboard and three more behind the wrist rest. However, they aren’t very sticky since the keyboard slides about easily. The wrist rest connections are weak and difficult to attach. However, once linked, the wrist rest feels solid.
Software
This K63 is compatible with a variety of operating systems. Everything works properly on Windows, and while all keys work fine on Linux and Android, there is no program for modifying them. On macOS, the context menu does not work, and on iOS and iPadOS, the function keys do not work.
The Corsair K63 Wireless has outstanding software support. Corsair’s iCUE software, which lets you reprogram keys and set macros, is used to customize it. You can store profiles, but there is no option for cloud synchronization, and the keyboard lacks onboard memory, so you’ll have to re-install the application and start over if you need to switch to another computer.
The Corsair K65 is entirely compatible with Windows, with the exception of the Pause Break and Scroll Lock, which are not compatible with macOS. You won’t be able to alter the settings because the program isn’t compatible with Linux, but all of the keys should still work.
The iCUE companion software is a dream come true. You may assign macros or presets to each key, and each key’s RGB lighting can be customized. Unfortunately, for novice users, the program is not very intuitive or user-friendly.
Ergonomics
Corsair K63
The Corsair K63 Wireless has outstanding ergonomics. It comes with a wrist rest, but it’s flimsy and uncomfortable. Fortunately, the keyboard’s profile isn’t particularly high, so that it may be used without it. The key spacing is standard, and just one inclination option is available.
Corsair K65
It is well-designed in terms of ergonomics. It has one inclination level and is equipped with a soft plastic wrist rest. Although it isn’t as comfortable as the wrist rest on the Corsair K95 RGB PLATINUM XT, it still aids in fatigue reduction. When you press the keyboard forward, the incline feet expand to the sides so they don’t retract accidentally.
Price
The Corsair K63 has a fair price of $109.99 on Amazon. On the other hand, the Corsair K65 has a price tag of $129.99 also on Amazon. Still a fair price considering the quality of materials used for manufacturing these pieces of hardware.
Conclusion – Corsair K63 vs K65
The Corsair K63 Wireless Mechanical Gaming Keyboard is an excellent keyboard with several features. It can connect to two devices at once via its wireless USB receiver or Bluetooth, and it can do so at the same time for easy multitasking. It has Cherry MX Red linear switches, which are extremely responsive, and it works with a wide range of operating systems.
It lacks onboard memory and cloud sync for transferring personalization choices, and its illumination is limited to a single blue color. Overall, it’s excellent for gaming or office computer.
The Corsair K65 LUX RGB is an excellent gaming TKL mechanical keyboard. The frame is well-made and has little flex, but the ABS plastic keycaps seem flimsy. It has a magnetically attachable wrist rest and is pleasant to type on. With the iCUE software, you can assign macros to any key and configure the RGB illumination. It offers excellent typing quality and low actuation force Cherry MX Red switches, but the long pre-travel distance isn’t perfect for gaming.
