Complete Review of the Corsair K70 RGB Pro Keyboard

The Corsair K70 RGB Pro is a high-end gaming keyboard that offers a variety of mechanical switch options in a solidly built case, making it an excellent choice for deep-pocketed gamers who want a competitive edge.

  • US Street Price $159.99

Corsair has offered the K70 gaming keyboard in various configurations since 2015.  The latest iteration is the Corsair K70 RGB Pro ($159.99), which meets the expectations set by its predecessors by offering the latest Cherry MX mechanical switches, per-key RGB backlighting.  , and many features were meant to attract professional gamers.  The last is how Corsair attempts to justify the "Pro" moniker—and the price.  We think it succeeds, with the K70 RGB Pro receiving an Editors' Choice award for best high-end gaming keyboard for Esports & Hounds.

What Makes the K70 a 'Pro'?

The Corsair K70 RGB Pro immediately differentiates itself from its "amateur" predecessors such as the K70 RGB.  The keyboard has similar layouts, but the Pro model relocates the profile, lighting, and game mode keys to the left edge instead of nesting them with dedicated media keys and the volume roller.  Corsair has replaced the standard plastic logo on the top edge of the faceplate with a glossy RGB version that glows in the same pattern as the rest of the keyboard.

This results in a familiar but distinct profile that makes it easy to tell the Corsair K70 RGB Pro apart from the K70 RGB at a glance.  But the changes are more than just cosmetic.  Corsair also offers a Pro version with Cherry MX RGB Red, Blue, Brown, Brown, Silent Red and Speed ​​Silver mechanical switches;  The K70 RGB is limited to Cherry MX Red switches.  (Corsair sent us two units for review—one with a blue switch, and one with a silver switch.)

Those switches are found under the Doubleshot PBT keycaps which should be durable enough to withstand a marathon gaming session.  That stiffness extends to the rest of the Corsair K70 RGB Pro, thanks to its brushed aluminum faceplate and solid plastic frame.  It's not a huge keyboard—it measures in at 1.6 by 6.5 by 17.5 inches (HWD) and weighs 2.5 pounds without the detachable palm rest—but it's satisfyingly dense.  It certainly doesn't look cheap.

One final physical difference between the Corsair K70 RGB Pro and its predecessors: the cable.  Where the K70 RGB relies on an attached, 7.3-foot-long cable, the K70 RGB Pro offers a detachable USB-C-to-USB-A cable that's just 6 feet long.  For those who keep their PC away from their keyboard, the extra 1.3 feet of loss can be a cumbersome one, but having a detachable cable makes it easy to transport the K70 RGB Pro without stressing or breaking its connectors  it happens.

Corsair K70 RGB Pro: Bring the pro to the tournament

Let's talk about even more features that help the Corsair K70 RGB Pro earn its name.  The most obvious is a so-called "tournament switch" next to the detachable cable.  Corsair says it disables custom actions and macros to prevent accidental activation, changes the backlighting to a constant single color to reduce distraction, and disables profile or profile switching.  All of those changes result in what is perceived as a "competitive mode of competition," as Corsair puts it.  Esports tournaments ban the use of some of those things;  There are other competitive disadvantages.

Will most people ever have to use a tournament switch?  Maybe not.  But for professional esports players who have to worry about accidentally using a macro or switching between profiles in the middle of a match, having physical controls can provide extra peace of mind.

The Corsair K70 RGB Pro also supports Corsair Axon Hyper-Polling technology which allows it to have polling rates and response times of 125Hz (8ms), 250Hz (4ms), 500Hz (2ms), 1,000Hz (1ms), 2,000Hz (0.5)  allows to offer.  ms), 4,000Hz (0.25ms), and 8,000Hz (0.125ms).  This is supposed to reduce the time between pressing a key and the connected PC registering that action.

Does it work?  I can't tell.  Corsair warns that using polling rates above 1,000 Hz requires more processing power from a connected PC, but I haven't noticed any difference on anything above that polling rate, so any  The performance improvement is probably limited at best.

Corsair iCue Software: Set it and forget it

Corsair Axon controls are found within Corsair's iCue software, which is also used to manage the K70 RGB's lighting, create macros, change key assignments, and update the keyboard's firmware.  The software works as you'd expect, and unlike Roccat's Swarm software, the iCue displays the scale at 1440p and 4K just fine.

The Corsair K70 RGB Pro offers 8MB of onboard memory that can be used to store 50 onboard profiles (the exact number, according to Corsair, "depending on complexity") and 20 layers of lighting effects.  There's also onboard macro recording, which means the iCue doesn't have to be used particularly often.  Simply go in to update the keyboard's firmware, set the polling rate to your desired level, and then use the Hardware Key Assignment and Hardware Lighting pages to save various settings on the device. 

Just be aware that navigating away from those pages after you've opened them—even if you haven't seen or modified a single setting—will display a warning that the settings haven't been saved.  Fortunately the "Don't show it again" option can prevent the dialog box from reappearing.

Corsair K70 RGB Pro Keyboard: A Worthwhile Investment for the Esports Crowd

Some miscellaneous features before I wrap up: The Corsair K70 RGB Pro features two feet at the bottom of the case that can be used to adjust the angle of the keyboard.  I found the keyboard comfortable to use either way, but it's nice to have the option to adjust the ergonomics.  The same goes for the detachable palm rest.  It's comfortable enough to use, and its magnetic connectors make it easy to attach or detach, although I was convinced at first that I was doing something wrong because the connections weren't quite as good as other palm rests.  seemed to.

Best about Corsair K70 RGB Pro Keyboard

The display used to show the multicolored Corsair logo is also used to show that Game Mode, Caps Lock, Number Lock, and so on are active.  This sounds like a good idea in theory, but I'd prefer an indicator on the keys (via RGB light) or dedicated LEDs (as with many other keyboards), simply because there's no need to be used on this display.  The symbols are easy to remember with a glance.  It's not the end of the world, but it's something that takes a while to get used to.

However, these are all minor complaints.  All told, the Corsair K70 RGB Pro is a solid choice given its $160 price tag with high-end build quality, many legitimately pro-minded features, and one of the better peripheral-optimization software utilities we've seen in a while.  is used.
