Coolermaster MasterKeys MK750 Mechanical Gaming Keyboard

Having been a user of the Membrane type of keyboards since I started using computers (age about 6), it was an amazing moment to be given the absolutely brilliant MK750 Mechanical Gaming Keyboard from Coolermaster to try out and review.

First impressions matter with keyboards because the market is flooded with so many variants. Keyboards now range from a few dollars, and function only to relay the words you are typing to the computer you are using, to the expensive keyboard capable of full customisation, lightning fast response time, lighting options and high end materials.

Standing out matters and  I believe CoolerMaster has achieved a standout in their choice of packaging. Just by moving subtly away from the black and red or black and grey gaming combination which has become the norm of late, they have secured a unique corner of the market. The deep purple and black draws your eye, even just for interest sake. The superior quality and outstanding features draw you in to look further. If you are looking for a keyboard which looks a little different to the others around it, or you enjoy a keyboard you can customize to be uniquely yours, then the CoolerMaster MK750 will be a great choice!



So whats in the box?

The keyboard, 1.8m  cable,  wrist support, keycaps with keycap puller and instruction manual.

The Keyboard. This is a plastic based, sleek yet stylishly simplistic design, featuring an anodized cobalt-aluminium top plate, which provides a high end look and feel to this great looking keyboard. The keys are raised, giving a floating switch effect to the board, and allowing the RGB lighting to be more visible. There is also a RGB light-bar around the outside of the keyboard, which harmonises beautifully with the lighting selection of the keys. Dedicated media keys have become a necessity on keyboards, and are of course included on the MK750. The design of the keyboard is tapered slightly from back to front, allowing seamless integration with the wrist support, and is able to be further adjusted using the flip out feet situated at the back.

The 1.8m detachable braided cable is a USB type C, and is managed at the top of the keyboard with built in cable management.



The detachable, magnetic wrist support is a selling feature all on its own. Gone are the use of flimsy plastic clips which inevitably snap off and render useless a hard plastic guard, which you weren’t totally convinced was comfortable anyway! The wrist support is a memory foam filled PU leather guard which is soft but still firm enough to give good support. Having a magnetic connection to snap to the front of the keyboard makes adding and removing a total breeze. The support  adds a certain degree of higher end luxury to the MK750.



Then we have the extra doubleshot keycaps. There are 9 extra keycaps included with the MK750, and they are in the stunning purple which features on the box design. These are WASD keys, ESC key and the 4 arrow keys. This allows the user to decide if they want an all black keyboard, or if contrasting keys are an option they wish to embrace. Also included is a key-cap puller which is designed to remove the keys without damaging them. A great addition to the custom feel of this keyboard.




The manual is written in a range of languages, and provides detailed instructions on how to change the light display settings on the keyboard.

There is software for the keyboard but it is not included in the box. The software allows you to change the colours, make macros, key mapping and save different profiles so you can have multiple keyboard setups for different applications.  NOTE: The keyboard is Plug and Play so you don’t have to have it installed first, BUT it is most certainly required for any customisations you perform. The software can be found on the CoolerMaster website, or by clicking the following link:  Coolermaster MK750



The difference was instantly noticeable. This particular keyboard featured the Cherry MX RED switches which are  designed specifically for gaming, with an actuation force of just 45g, and an actuation point (the distance it takes for the keyboard to register the key-stroke) of just 2mm. Cherry MX RED switches are linear, which means they offer a smooth and consistent key-stroke. Since the MX Red also lack the tactile bump in the middle of the switch, they are fast and responsive keys, but as they do not provide the  feedback the bump creates, they are less suited to typists. Out of all of the Cherry MX switches, the RED are the quietest, and offer a 50 million keystroke lifespan per key. The Cherry MX switches that Coolermaster use in their MK750 range of keyboards are Red, Brown and Blue. As mentioned, the Red switches are designed for gaming. Brown switches are your “All Rounder” switches which are good for gaming and typing, and the Blue switches are the loudest and best suited for typing applications.

Unlike the Membrane based Keyboards which are fairly quiet, Mechanical Keyboards are a lot more noisy, giving a distinct clicky noise sounding something like an old typewriter. It was this noise that at first put me off Mechanical Keyboards. I didn’t want the “click click” sounds to come through on my YouTube videos, but after testing and using one for about a week I found it wasn’t too bad and I quickly learned that I don’t have to hit the the keys to get a response.  Just out of interest, you can also buy key damping O-Rings or foam that can help reduce the noise levels. I didn’t have any so I cant comment on how effective they are but if the clicking sound is something that is an issue, there are ways to help reduce it.

The other very noticeable difference was the total customization of the MK750. You can change the LED lights under the keys to any of the 10 preset patterns, from having a solid color to a rainbow effect.



Keyboard Customisation

I mentioned earlier the customisation of the MK750, well lets dive into that more! The first thing you will notice when you plug your MK750 in is the flashy rainbow colours sliding across your Keyboard, as seen below:



These lights can be changed to up to 14 different programmed options, including Static, Rainbow Wave, Reactive Fade, Rain, Colour Cycle and also Custom. Custom allows you to setup your own colours, which can be individual keys or groups of keys. Changing between the different LED settings can be done “on the fly” by simply holding the ‘FN’ key and pressing F5.

The second customization is Macros. Macro key programming is especially useful in gaming, as you can have keys programmed to perform a particular special function. I am not just talking about pressing ‘W’ to move forward. I am talking about a key that when pressed, can look for a certain type of mob/creature/player and then auto target it. By setting this macro to a key, the player can target automatically even when looking the other way! VERY neat! I should point out that  Macros are not just for gaming. You may want to try and set up a special key for your software which you can press to help get your work done more quickly and easily.

The third is key mapping. This may seem like macros, but unlike macros which are programmed to do multiple things, key mapping is just setting up your keyboard so you can reassign keys to function as other keys OR you can simply disable keys so that when they are pressed they wont work!

The final part of the customization is Profiles. Once you have setup your LED lights, Macros and/or Mapping, you can then save those settings to a  profile. This is great, as you can then select that profile and use it at any time. You can save up to 4 profiles, so you can swap your layouts between different games or maybe have gaming  profiles and work profiles, switching between them as your computer usage changes. All you have to do is hold down the ‘FN’ key and press either 1, 2, 3 or 4 keys to switch between profiles. You can also rename the profiles for easier identification when you edit them.

So, overall my impressions of the CoolerMaster Masterkeys MK750 Mechanical Gaming Keyboard is … It is amazing!

Being plug and play makes it so simple to get up and running. The level of customisation the keyboard has is astounding, from changing the LED lights, making macros, remapping the keys and then saving them as separate profiles. The ease in which you can switch between the profiles is great! I know these things have been done on other keyboards but the CoolerMaster software makes the process an enjoyment and not a chore.

The wrist support is very comfortable and being magnetic, can be easily added or removed without the worry of snapping off the clips holding it to the keyboard.

The addition of the media keys is also a nice touch to any keyboard.

It is hard to pick any real faults with the MK750, but if I had to,  I would probably fault the louder noise of the key press of Mechanical keyboards compared to the Membrane Keyboards. To some the sound is like classical music to their ears, to others a total distraction. For me, after a week of using the MK750 the noise is now hardly a concern. The performance of the switches far outweighs the difference I found in the noise, because these keys are far superior to the key types I have been used to up to now.

IF I was to give a rating out of 10, it is a clear 9!


*A big thank you to our friends over at CoolerMaster for sending us the MK750 for review.
