power drawn from the PSU

post #1 of 3
Thread Starter 
I'm having a debate between my friend, he insists a 650w draws ALL 650w from the PSU, and thinks that 650w PSU means it uses that much all the time. I'm trying to tell him that it doesn't work like that, and it depends on the usage of the components. He doesn't listen, and I have no choice but to ask here to prove him wrong.

Am I correct?

yes, you are or almost everyone on this site would have massive power bills for idling computers

It doesn't work that way. Does a 500HP car engine generate 500HP all the time, every second?


















(the answer is no)
