    According to <a href="http://www.nsi.be/keyboard_specifications.PDF" target="_blank">this</a> at least 200A.

    Yikes! That's 200mA...

    Someone like Ruslan who does m/board repairs would probably know for sure, but I think the pico-fuse you blow if you do the wrong thing with a PS/2 keyboard while the system is on, may be 1Amp. More recent boards are protected with a polyswitch which is self-resetting. The reliable limit may be set by the mini-DIN socket, I wouldn't try to run more than a few hundred milliamp through the little contacts in them.
