Corsair Gaming K70 RGB RapidFire keyboard review - Product Showcase

Once connected and the PC powered up, subtlety. No flashing bright LEDs just yet, just red LEDs indicating caps-lock, scroll-lock and Num-lock. There's another button for the keyboards back-lit (red) keys, which can be adjusted in three brightness modes and off.

Basically you can cycle from off as shown above towards three stages of brightness as shown below.

Obviously we only have red LEDs activated here, but that could be any color preference (even per key) programmed.

The backside, plain and simple. We mentioned the rubber feet already. You can use standoffs as well to allow a little more height and create an angled position. Here you can clip on the wrist rest as well. The K70 RGB RapidFire is a heavy weight product, and combined with rubber feet will prevent you from the keyboard sliding away. It has a very firm grip on my desktop. The K60 and K70 model lacks extra programmable gaming keys that it's bigger brother the K90 and K95 do have. Some stuff however is programmable with the Corsair CUE software, but we'll address that later on in the article. 
 

The K70 RGB Rapidfiyaaah uses a dark and nicely braided cable that is roughly two meters in length. It is however a bit thick, something I personally dislike a little. What's the reason for that you might wonder ? Well, you probably spotted it already but there are two USB connectors at the end of the cable. One is for the keyboard of course, the other is being used as a pass-through for say your headset our mouse. At the backside you will spot an extra USB connector.
 

To you right you can see a BIOS switch, as explained this allows you to reduce the polling rate from 1000Hz to 500, 250 or 125Hz, or even strip it back to a basic BIOS mode. Corsair states that this is basically just to aid compatibility with some BIOSes. So in general very few people will ever need to touch the switch.
