Does the PSU power switch completely cut off the power?

I was wondering if the power switch on the back of the PSU completely cuts off all electricity to the computer, as if disconnecting the power lead, or whether it is part of a sub circuit in the PSU, in a similar vain to a standby switch, and there is actually some leccy still flowing?

Yes. It's not like power switches in typical appliances. Turning it off means after passing through the prongs for your power cable, there won't be anywhere else to go for the electricity, i.e. there aren't any contact between the receptacle (and filtering, there's usually the filtering there already) and the rest of the PSU.
 
yes. as entropy said. But in easier words,
it cuts of power the whole PSU.
 
Ok, thanks.

Tom.
