Im really not sure thats how it works. Especially not to anything like that degree. Your PSU probably had a fault.
A few review sites have re-tested old PSU's and the voltage control etc is sometimes out of spec and some of the readings get a bit sloppy, but they can still chuck out most of the juice.
I think its plausible that the reliable output could have dropped to 800W after 8 or 9 years without a design flaw or unusual failure, 750W seems unlikely, 650W absolutely not.
I was going to say thats pretty old for a psu I don't think I've managed to keep one that long they always develop some fault or other before they reach that age.
