Capellix is the second of Corsair's two big innovations unveiled at CES 2019, the other being the Slipstream wireless technology. Capellix is a new LED that is considerably smaller than a conventional surface-mount (SMD) RGB LED, with a volume of just 0.2 mm³ versus 2.8 mm³ of SMD LEDs. Such small sizes are achieved by stripping away the package layer of the diode, and bringing its substrate layer directly in touch with the PCB. Corsair has some big numbers to speak for Capellix.

A Capellix LED, according to Corsair, is up to 60 percent brighter, up to 60 percent more efficient, up to 40 percent lower power-draw, and has up to 35 percent higher service life than an SMD LED. Its smaller size also lets designers place more of them in a limited PCB area, increasing the number of diodes putting out light through a silicone or acrylic diffuser, thereby increasing the "resolution" if you will, of the RGB LED embellishment. The biggest use-case of these diodes, however, would be wireless peripherals, which could benefit from the lower power draw to improve battery life. Corsair will implement Capellix across its entire lineup of RGB LED illuminated products, including memory modules, case fans, wireless gaming peripherals,
