If the KM780 RGB was like the Cougar 700K then the MX780 RGB is much like the Cougar 700M. The design of these two mice is again very similar. The basic structure of the mouse is almost identical and it seems obvious that the MX780 RGB is a modified/upgraded 700M.

Measuring 130mm long, 70-93mm wide and 38mm tall it is quite a bit larger than the claw grip Aorus Thunder M7. Despite the bigger size the MX780 RGB is a relatively light mouse weighing just 111g, though it can be beefed up to 120g using the weight system. The G.Skill MX780 RGB is said to be able to tackle a range of games which includes FPS, MMORPG, MOBA and RTS titles. As a fan of RTS and FPS games I can confirm that the MX780 RGB works well here. The MX780 RGB supports a 1000Hz / 1ms polling rate, an 8200 max DPI, a maximum tracking speed of 150 IPS and maximum acceleration of 30G. It also comes with a 1.8m braided cable which features a gold-plated USB connector. It’s also worth pointing out that the MX780 RGB is only available in black with four zone RGB backlighting.

The MX780 RGB still uses premium components such as Omron switches and the Avago laser sensor. The switches are guaranteed for an insane 20 million clicks, so you should wear out more than a few mouse pads and possibly even desks on the way. The laser sensor’s 100 to 8200 DPI rating should cover anyone’s needs. The 32-bit ARM processor provides virtually instantaneous responses and 512KB on-board storage allows gamers to save up to three profiles directly to the mouse. In total, the MX780 RGB can store up to 30 different functions with most of them being comfortably accessible from the mouse itself by using the mode cycle button (to change to the next mode) or the instant mode switch (to temporarily switch modes while the key is being pressed).

Aesthetically, the MX780 RGB is an aggressive looking mouse that feels as good as it looks. Many of you, especially the lefties, will be pleased to note that this is an ambidextrous mouse. However it goes one better by including interchangeable side grips so left handed users can move that really nice thumb rest over to the right side of the mouse.

Alternatively you can install a thumb rest on both sides of the mouse and I actually really like this approach as it stops me from dragging my pinkie all over the mouse pad. The side grips pop off in seconds as they are fixed into place using two high powered magnets.

What’s so cool about this design is that you might never realize the side grips are removable if you weren’t told. There’s no chance they will fall off – you must grab them and pull quite hard to break the magnets.

Another great feature is the height-adjustable palm rest. Using the provided Allen key, the rest can be raised up or down to change the feel of the mouse. I raised it to about mid-way which was the most comfortable setting for me.

The customizations don’t stop there. G.Skill has included a weight system that lets you place a 4.5g weight in each side of the mouse behind the removable side grips, which is a really nice touch.

The MX780 RGB is also packed with a broad range of features, including eight fully configurable buttons. The on-the-fly DPI adjustment buttons are crucial, allowing gamers to select one of five pre-sets. Each pre-set is indicated by four LED lights which illuminate either blue, yellow, white, green, or red. Once the pre-set has been selected the indicator glows for about three seconds and then returns to the custom RGB value set by the user.

Underneath the MX780 RGB you will find that Avago laser sensor smack bang in the middle and seven high-quality PTFE glide pads for a smooth gaming experience. Another key point is the MX780 RGB’s compatibility with G.Skill’s Unified Driver System, which allows for easy configuration of all the device’s functions. Mode synchronization, macro sharing and many other features provide extra synergies if this device is used with other G.Skill devices such as the KM780 RGB Keyboard. Keeping that in mind, let’s check out G.Skill’s Unified Driver System in greater detail…
