How the Corsair K70 Compares with its Key Rivals

In this age of mechanical gaming keyboards, manufacturers of peripheral devices have already started releasing their own versions of the gaming keyboards with the goal of attracting gamers across the globe. As a result, mechanical gaming keyboards like Corsair’s K70 are facing stiff competition from other brands in the market.

Here’s a look at how the K70 squares off against two of its biggest rivals – Logitech’s Orion Spark G910 and Razer’s BlackWidow Chroma mechanical gaming keyboards.

K70 vs Orion Spark G910

Logitech G910 Orion Spark RGB Mechanical Gaming Keyboard – 9 Programmable Buttons, Dedicated Media Controls
  • World's fastest RGB mechanical gaming keyboard: Exclusive Romer-G Mechanical Switches with up to 25 percent faster actuation
  • Customizable RGB illumination: Personalize individual key lighting from a palette of 16 million colors ; Cable Length (Power/Charging): 6 feet (1.8 meter)
  • Arx Control App and smartphone dock: Instantly access in-game data on your smartphone or tablet without interrupting the game
  • 9 programmable G-keys: Create custom game macros to execute complex commands with lightning speed and accuracy
  • Dedicated media controls: One-touch control panel for quick access to play, pause, mute, volume and skip.Android 3.2 or later

The Orion Spark G910 features an enormous body with a hard plastic for resting your wrist and two additional rows carrying macro buttons. The Corsair K70, on the other hand, is also large but doesn’t feature any macro buttons. Unlike the Orion Spark, it fails to make the most of the ample space available on it.

The K70 comes with Cherry MX mechanical switches that meet the industry standards. The Cherry MX switches, which gamers adore, are available in three color options including red, brown and blue.

The Orion Spark comes with Romer-G switches that aren’t as good in terms of comfort and responsiveness. 

The Logitech Gaming Software beats the Corsair Utility Engine in terms of having a polished and user-friendly design. It can automatically scan your gaming system for exciting games, record macros and automatically set up your linked gaming profiles.

It is a daunting experience to create or link a gaming profile using the Corsair Utility Engine. The K70 outshines the Orion Spark in terms of having robust lighting options. The gaming keyboard also allows you to create custom special effects.

Corsair’s K70 is perfect for playing first-person games while the Orion Spark is best for playing games with multiple characters.

K70 vs BlackWidow Chroma

Razer BlackWidow Chroma: Clicky RGB Mechanical Gaming Keyboard - 5 Macro Keys - Razer Green Mechanical Switches (Tactile and Clicky)
  • Multi-Award winning Razer Mechanical Switches - Razer Green Switch with tactile bump and audible click for the best overall gaming performance
  • Extreme Durability- Razer mechanical switches are rated up to 80 million keystrokes and come with a 2-year warranty
  • Powered by Razer Chroma – Individually programmable backlit keys with 16.8 million color options
  • USB 2.0 and Audio pass through for easy cable routing
  • 5 additional dedicated macro keys

The BlackWidow Chroma boasts of a lean and sleek design. It doesn’t come with a wrist rest feature. It is more attractive than Corsair’s K70 gaming keyboard due to its matte finish and rounded edges.

The BlackWidow Chroma is ideal for use in a gaming workstation or nook despite lacking a wrist rest feature. The K70, on the other hand, can be used anywhere since its features an enormous body, discrete media control keys and a comfortable wrist rest.

The K70 beats the BlackWidow Chroma in terms of the keys. It comes with attractive Cherry MX mechanical switches unlike BlackWidow Chroma that comes with Razer Green switches. Though they’re optimized for gamers, the Razer Green switches don’t feel responsive and comfortable when using them.

However, when it comes to value, the K70 is better than the BlackWidow Chroma since it has comfortable and responsive switches.

The Razer Synapse 2.0 on the BlackWidow Chroma outshines the Corsair Utility Engine 2 on the Gaming K70. You can easily create gaming profiles and link them with games using the Razer Synapse 2.0 software. The only challenge you’ll encounter using this software is when you’re creating macros. The CUE2 makes it hard to create macros and gaming profiles for the gamers.

The BlackWidow Chroma has a limited library of special effects. However, its limited library gives you an opportunity to create special effects. Consequently, the Gaming K70 boasts of a large library of customizable special effects.

You can create and link custom color profiles with your favorite games using this device. Despite being difficult to use, the K70 lets you enjoy its wide lighting options.

Both the BlackWidow Chroma and the K70 can be used to play first-person shooter, adventure or action games. You can also use them to play real-time strategy games. However, the difference between these devices emerges in the macro features. The BlackWidow Chroma is for gamers who like to micromanage a lot when playing games unlike the K70, which doesn’t offer this type of convenience.

The Cons

1. Difficult to Disassemble

The K70 is quite difficult to take apart. For you to open it, you’ll have to remove all its keycaps. You’ll find up to 20 screws under the keycaps that you also need to remove.

There are two other screws beneath the logo plate that are hidden and inaccessible. The only option you have is to break the mechanical keyboard for you to access its inner parts.

2. Poor Warranty Service

Corsair offers a 2-year warranty on every peripheral device that it makes. However, the warranty appears to be limited in a broad way.

For instance, if you accidentally spill a drink on the keyboard, it is difficult to open and clean it. The company doesn’t state in the warranty policy whether the challenges associated with disassembling the keyboard are covered.

3. Switches are Prone to Damage

The K70 boasts of Cherry MX switches that are available in three colors. The problem with the switches is that they lack a top panel to protect them against scratches or any other form of physical damage. They can end up damaged due to the sideways force that is applied to them.
