3 extra wires on 24 pin connector on PSU - what are they for?

[berghaushouse]

I recently acquired an Antec CP-850 which was missing it's 24 pin plastic module (i.e. all the wires were just all over the place) after reconnecting all the wires into a new plastic connector I'm left over with 3 wires that I'm not sure what to do with.

One is a brown wire which I've read is a 3.3V Sense Wire and I've read (after a quick Google) that it's optional, so I'm happy to ignore this one.

One is a black and yellow cable, it's rather thin.
The other is a red and white cable, it's also thin.

I can't find anything helpful after Googling - I have hooked up my PSU to a couple of computers and it appears to be working fine without these 3 wires connected so I'm tempted to just ignore them (maybe wrap them in some insulation tape and tuck them away in the sleeve?).

Thanks in advance.

Think that is for certain high end boards that require additional power, if your board doesn't require it then fold the wires back and use a zip tie to secure them
