BlackWidow Lite with PS2 adapter | Razer Insider
Skip to main content
Hi. I need to connect my BlackWidow Lite to PC via USB-to-PS/2 adapter. I wonder is keyboard will work in this case? Can it send PS/2 protocol signals?
TBH, I dont think this will still work with modern (Razer) keyboards, as they demand a higher current, especially because of their backlighting.

https://en.wikipedia.org/wiki/PS/2_port says PS/2 is max 275mA

I guess the Blackwidow Lite will be above this spec. My Blackwidow X chroma has 425mA, for example. (you can check on the bottom of your kb - on the left side of the product plate)
Thanks, parac1oXX
My BlackWidow has 500mA
