Corsair K70 Review: A Look at Its Features and Specs

corsair k70

For this review, we will look at the Corsair K70 and show you why your game can only get better with the right gaming keyboard. Online gaming has become an empire in and of itself, with millions of people around the world playing every day on their home computers.

While consoles like the PlayStation and the Xbox have a dedicated fan base, it seems like the most diehard gamers have found their place on their home computers.

That’s why it’s important to know what you’re looking for when it comes to this important hardware. Specialty keyboards like the Corsair K70 RGB Rapidfire can be intimidating at first glance.

Why Use a Gaming Keyboard?

Unlike the consoles, which come with their peripherals and controllers, home computers require a mouse and keyboard.

Most generic home computers do not come with game-ready hardware, so the tried-and-true player must find their attachments to aid in their pursuit of glory and loot. When you get into more competitive play, especially when playing against online gamers, then your keyboard and mouse can make all the difference. 

Speed, timing, and accuracy are paramount when honing your skills in a game. As athletes require the best equipment to bring the best out of their abilities, so do people who play games at a competitive level. Even if you don’t consider yourself a “professional” or serious gamer, every player can benefit from using the best tech available at their fingertips.

Gaming keyboards are typically designed with flexibility and customization in mind. Each player is as different as each game, and the more options you have to custom-tailor your hardware, the better your playing experience.

Product Specs

Corsair has pulled out all the stops for this keyboard, putting in features that not only enhance the playing experience but also offer the more advanced player options to grow their skill. ​


There are a lot of features we could talk about, the aluminum alloy body, the back-lit RGB system, or the CUE application used to customize the board. That being said, we want to call out some features that make the Corsair K70 one of the premiere gaming keyboards available today.

Cherry MX Mechanical Keys

One of the biggest headaches for high-level gamers is a phenomenon known as “ghosting,” when rapidly pressing keys. Most standard keyboards do not have the rapid-fire system needed to register every keystroke in fast enough succession, leaving the fast-play gamer pressing a key more times than the computer registers. 


This is a problem when you’re trying to use quick-fire actions or advanced combination macros to execute in-game commands. The K70 uses gold contact Cherry MX key systems the fastest response key mechanics on the market today.


The anti-ghosting systems are built into the keys and actuators, giving you lightning fast response time, even when using swift, repeated presses of the same key.

Braided Cord with USB Pass-Through Port

This might seem like a small feature at first glance, but having a durable cable to connect your keyboard is more important than you might realize. Though wireless boards are nice for keeping your space neat and tidy, they are incapable of offering the power supply needed to run the advanced features in a gaming keyboard.


Forget about backlighting and onboard macros because your battery will be primarily wasted on the Bluetooth module inside the board. That’s why having a strong and durable cable is so important to an advanced gaming module like the K70. This is especially important if you plan on transporting your gaming peripherals between different gaming stations. 

  

The standard USB cables are flimsy and can wear down quickly. This braided USB cable is made for movement and easy connecting on the go. The added pass-through socket is also a lifesaver, offering a quick access spot to plug in another device for operation or charging.

Logitech G613

Corsair K95 RGB Platinum

The K95 is comparable to the Corsair K70 for obvious reasons. Another entry into the “K” series from Corsair, this unit throws in all the bells and whistles you could imagine. 


A wired and mechanical gaming keyboard, this unit has a gorgeous RGB back-lit system, 8MB of onboard memory, and a full suite of programmable keys on both flanks.

Price

This is the average price range we found from most online retailers. There might be a small price break if you are an Amazon Prime member.

Ease of Use

Though the media controls on the right flank are fairly intuitive, when it comes time to program the left flank “G” keys, you might need a little tutorial on the software. 


Using the Corsair system, called CUE, you have a full featured control suite that lets you program everything from combo-macros to shortcut bindings.


The RGB back-lit lighting can also be customized down to the individual keys. There is a lot here to learn, so this system might be for the more experienced gamer.

Features

This keyboard has every feature you could want out of a wired gaming board. The CUE system from Corsair makes an individual key mapping possible, giving you one-touch control for all your gaming needs. 


The individual light mapping serves a practical purpose in lighting the bind keys and showing your remapping of macros and shortcuts. 

  

All of your playable keys are back-lit in vivid color as you play. The 8MB of onboard memory makes saving your profiles simple, especially if you need to move your board from one computer to another.

Design Quality

This model shares a lot of the same manufacturing strengths as the Corsair K70, for obvious reasons. The manufacturer, Corsair, has set a standard for an aluminum frame construction, making a tough and durable board that can hold the heavier mechanical keys most gamers prefer. 

  

The tactile feedback from the Cherry MX Speed keys (a system pioneered by Corsair) gives a strong non-ghosting press without being as loud as a hammer hitting a nail. This is a common complaint from most mechanical keyboard users.

Warranty

All gaming keyboards from Corsair come with a two-year limited warranty. If purchased through Amazon, it would qualify for the thirty-day “dead on arrival” return policy.

Pros

  • Durable aluminum frame
  • 8MB onboard memory

Cons

  • Not suited for easy transport
  • Complicated programming options

HyperX Alloy FPS RGB

The HyperX Alloy is a compact and wired gaming keyboard that emphasizes transportability. The compact-form design is made from a steel alloy frame, making it tough and sturdy. 


The detachable power cable makes movement a lot easier if you need to get the board from one computer to another. The beautiful RGB back-lit keys can be customized to three different profiles, all of which can be stored on the onboard system of the keyboard itself.


That onboard memory makes moving this unit from one system to another easier as you don’t have to worry about resetting your custom controls every time you move to connect to a new gaming system.

Price

This price is based on the range found for purchasing online. There could be a price break if you are an Amazon Prime member.

Ease of Use

We like the compact design of this keyboard, and that says something compared to the Corsair K70. While the other models on this list have flanked buttons, often called the “G” panel, the HyperX Alloy FPS RGB has a standard QWERTY board with no standalone macro keys.


This may seem like a huge drawback for some, but these keys have been sacrificed to make a streamlined, compact, and easy to transport option for the gaming professional. The easy-to-detach cable and compact design make it simple to swap and transport between gaming systems.

Features

Without the macro keys that are usually standard for gaming keyboards, there aren’t too many digital features to talk about. 


The back-lit keys are beautiful and can be customized for up to three different profiles, all of which are stored on an onboard system. The detachable cable is a neat feature, along with a back-end USB charging station, making it versatile and useful as a standard-use board.

Design Quality

We really liked the solid metal frame of this unit. When put up against the others, this compact little board seems stronger and easier to transport. While most boards are not made for regular travel, sometimes you need something that can go where the action is. 

  

The HyperX makes that movement easy by giving a strong backbone to mount the mechanical keys. Reattach the cable and load the onboard RGB profiles onto whatever machine you’re using and you can hit the ground running and shooting.

Warranty

This product comes with the standard limited warranty from the manufacturer. If purchased through Amazon, it is covered by the “dead on arrival” thirty-day guarantee.

Pros

  • Strong & compact
  • Easy to transport

Cons

  • No macro keys
  • Limited programmability

Logitech G613 Lightspeed Wireless Mechanical Gaming Keyboard

The single feature that sets the Logitech G613 from the Corsair K70 is the wireless capabilities, and that’s pretty much it. Wireless keyboards are great for the average user, especially if you hate having a bunch of cables running over your desktop. 

  

The fact about gaming keyboards is they require a lot of power to deliver on features like custom lighting and fast response time. Battery technology is nowhere where it needs to be to supply the juice required for the standard gaming keyboard.


A wireless keyboard can’t handle the workload most gaming-pros need, so the Logitech G613 falls woefully short of minimum expectations

Price

This price range is for the Logitech G613 as found on several online retailers, including Amazon. There could be a price break for this item if you are an Amazon Prime member.

Ease of Use

The G613 was a little spotty on connecting to the receiver. Instead of using the usual Logitech based Universal receiver, this unit uses a special Lightspeed system receiver. The problem of reconnecting after coming out of standby repeatedly happened, slowing down the progress of jumping right into the game.

Features

This particular keyboard is a standout because it’s both wireless and mechanical, giving a tactile response to typing that’s often missing from wireless units. That’s fine if you’re looking for a good wireless option for basic tasks. But when it comes to gaming, you might want a little more than just the “G” keys placed on your left flank.

Design Quality

The keyboard is sturdy and has a great mechanical response, but the Lightspeed connection system leaves a lot to be desired. The board itself works fine, with a seventy million click life expectancy on the keys. 


The problem of reconnecting once coming up from standby kept popping up, making the turnaround on switching apps or playing through cut-scenes a real drag.

Warranty

This item comes with the standard warranty from the manufacturer, Logitech. If you purchase this through Amazon, it qualifies for their “dead on arrival” warranty for thirty days.

Pros

  • A wireless mechanical board
  • Easy to program “G” keys

Cons

  • Spotty reconnection
  • Does not use Logitech Universal Connect

The Corsair K70 - The Verdict 

After comparing the four different keyboards, we still believe Corsair comes out on top. Both the K70 and K95 Platinum were exceptional gaming keyboards. The K70 was the best value with the easiest out-of-box operation. 

 The keyboard had all the features most gamers look for but didn’t have to sacrifice design quality to fit them in. We believe the Corsair K70 is one of the best keyboards on the market and is worthy of even the most fiercely competitive and tech-savvy gamer.
