Hey there Oomanamemni,
My Virus KC AC adapter has the following markings on the end that plugs into the Virus:
Side 1:
3A 125V
SP-016A
Side 2:
(SR) E147517
COXOC
The only part that might be a little off is the (SR) marking. I have not seen it before on an AC plug, it might not be exactly that but that's what it looks like to my eyes at 7:01 AM before my coffee is fully ingested. Hopefully these details let you ID your KC adapter. I do not have a gaming system so I can't help with that.
Good luck!
