what's the use of the square 12v psu cable

[een]

One of the power cable from the psu to mobo is the square 4 pin 12V one I think...
I accidentally booted up the comp without plugging this in, it works... Is it actually useful, I got an nforce2 athlon mobo by the way...

 

[Confused]

It provides extra 12v power to motherboards/cpu's that need it. If there is the connection on the motherboard, it's best to plug it in. It was originally only on P4 boards, but I have seen a couple of AMD boards with this power connector

I guess there's no harm in doing that...
But It detracts from having a cableless case when viewed from a side perspex window, as this slot is all the say on the left in my mobo...

awwww



Dell's Poweredge 400SC has the power supply w/ the plug but the mobo doesn't have it... oh well!

The computer I just built for my aunt with an Epox 8RGA had one of those connectors.

If you plan it right... you can pretty much hide that cable even if it is plugged in.
