In the last months my Cooler Master QuickFire TK mechanical keyboard developed several problems. Some of the LEDs under the keys stopped working and more importantly, the keyboard started to disconnect from the computer at random moments. Reading around online, this seems to be a common problem with the Cooler Master Quickfire series. The USB cable is removable and the solder joints of the USB connector wear out over time. Most of the times when the keyboard disconnected I was able to reconnect it by wiggling the USB cable around a bit in the connector, but after a while that did not work anymore and the keyboard was not recognized by the computer at all.
As usual, this happened right after the warranty period expired, so I had to repair the keyboard myself. Instead of replacing or re-soldering the USB connector I decided to solder the cable directly to the keyboard, and removing the connector altogether. The downside of this method is that I could not disconnect the cable from the keyboard anymore, but I never did that anyway as the keyboard sits permanently on my desk. The upside is of course that would never have to deal with a broken connector again.
To help you repair your Cooler Master QuickFire keyboard, I have described below how to do this, as well as the materials and tools that are required.
The specific keyboard I repaired is a Cooler Master QuickFire TK, but these instructions can also be used for the Cooler Master QuickFire Rapid and QuickFire Stealth mechanical keyboards, as they are similar mechanical keyboards with a similar removable USB cable.
After soldering the USB cable directly to the keyboard it does not randomly disconnect from the computer anymore, which is great. I am a bit disappointed in having to deal with the build quality/quality control problems of the keyboard which, in my opinion, should not happen at this price point. Either way I am glad that was able to extend the keyboard’s lifespan. When it works it is a great keyboard and I prefer to keep using it instead of throwing it out and buying a replacement.
