Keyboards sold with the Corsair OPX

Corsair K65 Pro Mini 65% · $130 The Corsair K65 Pro Mini is a 67-key wired 65% gaming keyboard with Corsair OPX linear optical switches, PBT double-shot keycaps, and up to 8,000Hz polling via AXON, though its switches are soldered rather than hot-swappable.

Which keyboards can use it?

The Corsair OPX needs a keyboard built around Corsair's own optical-sensing PCB; optical light gates are proprietary, so switches from other optical makers do not fit, such as the Corsair K65 Pro Mini. It is not compatible with standard MX mechanical hot-swap sockets. Check the keyboard manufacturer's supported-switch list before buying.
