A Closer Look
Now that the SK650 is unboxed, we get our first real look at the keyboard. Immediately you can see just how much smaller the low-profile Cherry MX switches are with the extra slim caps. We also noticed the SK650 weighs significantly less than other mechanical keyboards we have reviewed weighing in at 670g.
The SK650 is built with a single piece aluminum top which has a stunning brushed aluminum gunmetal finish.
Looking to the side, the SK650 is slightly angled with it being a little taller at the back. Taking a closer look at the top edge of the SK650, we really love Cooler Master’s attention of detail by chamfering the edges. It’s the little touches that can turn a nice keyboard into a great one.
Like all other Cooler Master keyboards we have reviewed, they have opted to go with the floating switch design. Located at the back of the SK650, is a USB-C connector which is used for its detectable wire.
The bottom of the SK650 contains 4 rubber pads at the corners and has no adjustable feet. We are not sure why Cooler Master decided to remove these but we will have to see if we miss them during testing.
The included USB-C cord includes gold plated connectors, a braided black sleeving, a custom purple plastic insert, and an embossed Cooler Master logo.
To get a look at the installed low-profile Cherry MX Red switches, we remove 6 of the keycaps with the included keycap puller. The switches themselves are about 35% smaller than a normal red switch but still maintain that same red switch feel.
Looking at the extra slim keycaps they are approximately half the height of a normal keycap to accommodate the smaller switches. Checking out the top of the keycaps, they are much flatter giving them more of a laptop feel than a desktop keyboard.
Plugging in the SK650 we can see the RGB LED is installed at the top of the switch. One thing we did notice about the low-profile RGB switches is that they are a little dimmer than regular Cherry MX switch.
By default, the SK650 starts out with a static purple preset which mimics Cooler Master’s classic royal purple color.
If at any time you wish to change the color or effect of the RGB LEDs, you can do so using the Cooler Master button at the bottom of the SK650. This can be used in conjunction with function keys at the top to cycle through all the preloaded effects.
Turning off the light, even with the dimmer RGB LEDs the SK650 is still plenty bright.
Another one of the nice attention-to-detail elements of the SK650 is the slim light bar which goes completely around the keyboard.
