I had borrowed sunny's DMM and i got perfect readings on that. At idle, +5V showed up as 5.05V and +12V showed up as 11.92V.. not bad i guess.. Asus probe read 4.919V and +11.712V.. I bot a new DMM too, today
What abt this guys..... this is on a Powersafe 500 Watts. Is it ok??? or is it too much??? what can I do to reduce the fluctuation(with the exception of changing my PSU)???
