cheap non rgb keyboards

I’m using some cheap wired keyboard that came with an old desktop and it works fine.

what is the name of your keyboard if you know?

It’s an acer SK-9020. Super basic keyboard. But it works

The only thing to be concerned about with cheap office keyboards is lack of key rollover also called anti-ghosting.  Some keyboards will interrupt a command when multiple keys next to each other are pressed, but if you are playing without issues, then you're good to go.  An expensive keyboard isn't needed if you can press all the keys when you need to, and they all respond correctly.

thanks. but will the cheap keyboards work

Yes, most of them do function.

thank u 1 more question do u know if the logitech k120 has good enough key rollover for gaming?

I looked it up, but since it is an office keyboard there is no mention of anti-ghosting or rollover so all I can really say is to try it if you already have it.

EDIT: I found a thread online with a user saying they have 6-key rollover and if that is true it will be fine.
