Warranty
Corsair includes a 2-year limited warranty on the K65 PLUS Wireless. Register your serial number at corsair.com within 30 days of purchase to activate warranty tracking. The hot-swap PCB itself is covered under the same warranty terms — switch swapping does not void warranty as long as you use compatible MX-style switches.
FAQ
Which switches are compatible with the hot-swap PCB?
Any standard 3-pin or 5-pin MX-style switch. That covers virtually every aftermarket switch from Gateron, Kailh, Akko, Cherry, JWK, and most boutique brands.
What’s the wireless latency on 2.4GHz?
Roughly 1ms additional latency over wired in most testing. For practical purposes, indistinguishable from wired even in competitive FPS gaming.
Can the K65 PLUS be used with consoles?
Yes via USB-C wired mode. Xbox Series X/S and PS5 both support standard USB keyboards. Wireless modes are not console-supported.
How long does it take to charge?
Roughly 3 hours from empty to full via USB-C. You can use the keyboard wired while it charges.
