Switched mode power supplies don’t like being turned on and off repeatedly but a good quality supply should be OK Why are you asking this question as turning off the computer at the supply after you have shut down is normal use and should not cause any problems? The alternative of leaving the computer powered up all the time after you have shut down will cause the power supply to have a shorter life and cost more in electricity.

Read the last line of the previous posters message more thoroughly :p

turning the psu completely off (as long as you shut windows etc down properly)
will give you a longer life for your psu

I don't know about that. That's how the PSU's are designed to be used. My computers each pull about 1 watt when powered down (PSU switch on) as measured by my Kill-a-Watt meter.

And two of my systems run 24/7 except when I am on vacation.
