Best Corsair Nightsword RGB Black Friday and Cyber Monday Deals & Sales 2020:

Among Corsair’s wired mice dedicated to FPS and Moba, the Nightsword RGB is more compact than the Ironclaw model and more comfortable than the M65 of the same range. With its adjustable mass, it mainly competes with the Logitech G502.


Nightsword , or “sword of the night” in French, this is the name chosen by Corsair for its new gaming mouse dedicated to FPS and Moba. The manufacturer persists in the use of names referring to edged weapons and the Nightsword thus arrives after the Saber , Harpoon , Scimitar , Glaive and Ironclaw . So let’s see if its cutting edge is as effective as that of its predecessors and worth the € 79.99 requested when it was launched.

Discovering the Corsair Nightsword RGB, it’s hard not to see a resemblance to the famous Logitech G502  : same main buttons that end in a point, two buttons along the left click, two buttons still above the wheel and three on the left edge, one of which acts as a “sniper” button.

A left edge which also supports the thumb, as on the G502 again. After all, as much to recover the good ideas from the competition, especially as the resemblance stops there, Corsair also bringing its paste to the design of the mouse.

First, note that the Nightsword is a little more imposing than its rival at Logitech: we thus measure dimensions of 130.8 x 88.5 x 43.5 mm, an almost equivalent length (132 mm for the G502), 3.5 mm more in thickness and especially 13.5 mm more in width. If the larger thumb rest partly explains this difference, the shell itself is also wider (+6 mm).

Consequently, the palm of the hand is better supported, but we inevitably lose a little in handling with such a template, similar to that of the Dark Core RGB of the same manufacturer. The Nightsword is therefore intended more for big hands and followers of palm or claw.

Good news, these fairly generous proportions do not translate into excessive mass. Without being light, the Nightsword RGB remains under 120 g (119 g according to the official site, 108 g measured by us and … 115 g according to the inscription on the box, probably without taking into account the cable in the latter case). Like the G502 there again (except the wireless , lighter Lightspeed version ), Corsair does not however aim for maximum lightness and even offers to weigh down its mouse up to 141 g with 3 small full masses


Corsair even pushes the concept a little further by detecting the insertion of the weights to indicate in its software the total mass thus obtained and the position of the center of gravity. A fairly gimmicky function, however, in our eyes, insofar as it has no particular impact on the functioning of the mouse.

The physical customization of the mouse stops at this mass adjustment. Corsair does not offer an interchangeable slice, unlike what can be done with the Dark Core, for example. Too bad for those who hoped for support for the little finger, even the ring finger.

In return, this absence of interchangeable part allows you to enjoy a very good finish, with a set of materials of the most beautiful effect. The rubbery and textured material of the slices, which ensures good adhesion of the fingers, is thus surrounded by parts in shiny black plastic continuing all around the mouse. We find this material on top, before the wheel. The rest of the shell is made of a soft, textured plastic. The main buttons, for their part, use a slightly grainy, more resistant mat plastic. Finished the plastic aspect of too many other mice of the manufacturer, the Corsair Nightsword RGB seems much more elegant.

This rather pleasant design is enhanced by four bright zones lit by multicolored LEDs (RGB). Two are divided into three, at the base of the mouse and on the front, the third is at the heart of the wheel and the fourth is none other than the logo located at the base of the shell. The light transitions are neat and can be synchronized with the other Corsair peripherals thanks to the iCue software (see box).


Regarding the main buttons (left and right clicks), the Corsair Nightsword RGB has Omron switches guaranteed for 50 million activations. The clicks are fairly discreet and relatively sensitive (around 45 cN of activation force according to our measurements), which is perfectly suited for fast games of the FPS or Moba type.

Corsair, alas, did not find it useful to use other mechanical switches for the other buttons of its Nightsword. If this is not annoying for the buttons located on the top, allowing to change the sensitivity on the fly and to switch between the profiles of use, as well as for the Sniper button (which is left pressed to activate its function) , however, it is much more regrettable for the two edge buttons which would have deserved better care. Their mechanism also suffers from too much movement, causing an unpleasant spongy feel. Note also a lack of separation between the two which can generate errors in the precipitation.

On the side of the wheel, the balance is more positive, the notches being well marked, without however affecting the fluidity of the scrolling. We could just have wanted side switches, which would have added two additional functions and the possibility of scrolling documents horizontally, in office automation.

Finally, note that the braided USB cord, as thin as it is, is too rigid, which can hinder movement if it comes up against equipment placed in front of the mouse. What give grain to grind to the supporters more and more of wireless.


Already seen on the Ironclaw model, the Pixart PMW3391 optical sensor is also used on the Nightsword. Derived from PMW3389, it supports accelerations up to 50  g and speeds up to 10.16 m / s. Top-notch performance that guarantees foolproof tracking, even with very sudden and large movements, typically performed by FPS players who use fairly low sensor sensitivities.

This Corsair Nightsword RGB does not prevent the sensor from being able to climb up to 18,000 dpi, which. However, is still just as useless today. Remember that moving the mouse over 1 cm at. 18,000 dpi almost suffices to make the cursor cross the width of two Ultra HD screens. In a video game, it is guaranteed to be dizzy and loss of precision guaranteed. At more reasonable sensitivities, this sensor is nevertheless very precise and benefits from an impeccable optical tracking, without smoothing or acceleration which could disturb the fidelity of the movements. We would simply have liked to be able to set the height of the sensor drop to a slightly lower level, to eliminate even better the small parasitic movements that can occur when we lift the mouse to center it.

Surface recognition is also very good, although glass and other reflective or transparent materials should always be avoided. We will in any case only recommend too much the use of a good mouse pad. So as to optimize the precision and the glide while reducing in passing the wear of the pads.


  • Excellent optical sensor, fast and precise.
  • Comfortable grip.
  • Good build quality.
  • Many buttons, well placed.
  • Neat backlight.


  • Slice buttons too soft, not very reactive.
  • USB cable too rigid.


The Corsair Nightsword RGB narrowly misses the 5th star, mainly because of its too disappointing edge buttons in a very competitive segment which leaves no room for error. It is however a very pleasant to use, precise and comfortable mouse, which generally fulfills its contract and will delight players with large hands who find the size of a G502 too narrow. If we add to its equation its devastating design. This can be enough to convince a good number of users who will be able to put up with small faults.
