sokkanet Posted August 10, 2009 Share Posted August 10, 2009 For the last couple of days I've been checking things in the house for power usage. Since the usage of the computer suprised me I've done some troubleshooting. If I turn the computer off, the computer is using 32 watt. If I pull the power cord from the PSU it goes down to 0 watt. On the back, the psu has a on/off switch, if I set it to OFF, it will still use 14 watt. I would imagine that setting the switch to OFF would use the same as pulling the cord. Is there something wrong with my PSU, or is there a reason that it's using power even when turned off? Link to comment Share on other sites More sharing options...
Yellowbeard Posted August 10, 2009 Share Posted August 10, 2009 How are you measuring this power consumption? Link to comment Share on other sites More sharing options...

Yellowbeard Posted August 11, 2009 Share Posted August 11, 2009 What is a watt-hour meter and how is it connected to your system? Link to comment Share on other sites More sharing options...
sokkanet Posted August 11, 2009 Author Share Posted August 11, 2009 I'm not sure if it's the right term to use or not. Here's an example, where you can see how it could look, this one is not identical to the one I use. I could not find a picture of it on the net... but you get the idea! http://www.sparkfun.com/tutorial/Kill-A-Watt/Kill-A-Watt-0.jpg I guess you know what it is and how it is connected. If not here it goes: You put this one in the power jack on the wall, and put a power cord from the PSU to the meter. That way all power will go through this thingy, and it will measure how much power it uses! Link to comment Share on other sites More sharing options...
