Manufacturer description

The RK ROYAL KLUDGE RK87 Sink87G is an 80% tenkeyless mechanical keyboard built for gamers who want desk space back without giving up a full function row. Dropping the numpad frees room for wide, low-sensitivity mouse sweeps, which is why TKL boards like this one are an FPS staple. You get 87 keys on tactile brown switches, so each keystroke gives a bump you can feel without the sharp click of a blue switch, making the RK87 workable for late-night raids and daytime typing alike. Connection is your call: plug the nano USB receiver in for 2.4G wireless, or run the USB cable for wired mode…

SpecPicks Verdict

SpecPicks scored RK ROYAL KLUDGE RK87 Sink87G RGB 80% Mechanical Keyboard using a rating × review-volume × price-fit model applied to published specs and reviews across the gaming peripherals category. RK ROYAL KLUDGE's gaming peripherals lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Common buyer scenarios for gaming peripherals of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent.

Frequently Asked Questions

Is the RK87 Sink87G wireless or wired?

Both. Insert the nano USB receiver for 2.4G wireless, or connect the USB cable for wired mode. A switch on the bottom of the keyboard selects the mode, and plugging in the cable while the receiver is connected shifts it to wired automatically.

How long does the battery last?

The 1850mAh battery is rated for up to 100 hours of standby time with the backlight turned off. A full charge takes 3-4 hours. Running the RGB lighting will reduce that figure.

What switches does it use and how loud are they?

This model ships with tactile brown switches. Browns give a noticeable bump partway through the keypress without the audible click of a blue switch, so they sit between linear reds and clicky blues on noise.

Can I program macros on this keyboard?

Yes. It supports three sets of macro recording triggered with FN+Ctrl+Q, W, or E, and RK ROYAL KLUDGE provides programmable software for further customization.
