You can go into power options in control panel if you have windows and configure your system to turn off after a duration of it being idle. Raiddinn a b ) Power supply February 26, 2012 9:19:31 PM Sounds like the new PSU might not be a good one. The newer better PSUs are usually able to work with power saving things built into Windows. Mind saying what the old and new PSUs are? The power settings inside windows shouldn't have changed when you put in a new PSU. I would be extremely surprised if they did. Can't find your answer ?
