kpapad Posted March 1, 2015 Report Share Posted March 1, 2015 I just bought a 530w Hamburg to replace an older thermaltake which died. I have a budget power meter which I use recently and seems reliable. I plug it in, having the psu's switch to OFF and what do I see? A consumption of 15 Watts! Is this normal? Am I missing something? This PSU is also supposed to have an ERP LOT 6 ready certification which is supposed to minimize standby power consumption. But having the PSU switched off does not even fall into the standby category. I'm not an expert, but unless there is an explanation I'm missing, it is utterly unacceptable... Anyone able to elaborate? ps. switched on I get a 27 watt reading, but that's due to motherboard consumption. Quote Link to comment Share on other sites More sharing options...
Tt Andy Posted March 2, 2015 Report Share Posted March 2, 2015 Hello kpapad, Welcome to the forums, It seems like there might be a issue with your power supply, your right when the switch is set to off it should NOT have a consumption of 15 watts. In order to determine the problem, can you please help me try the following steps 1) Plug the power meter to the wall and have nothing connected to it and see if there is any kind of power consumption? 2) Plug on only the power supply cord into the power meter and see if there is any power consumption? 3) Have you tried to plug anything else into the power meter? Thanks Quote Link to comment Share on other sites More sharing options...
kpapad Posted March 2, 2015 Author Report Share Posted March 2, 2015 That was my thought too, so I had allready checked these. Now that you asked I did the test again. Here it is: 1) Plug the power meter to the wall and have nothing connected to it and see if there is any kind of power consumption? 0 watt 2) Plug on only the power supply cord into the power meter and see if there is any power consumption? cord unplugged from pc end 0 watt - cord plugged in again 16 watts, 230v, 0.07amp (switch to 'OFF') 3) Have you tried to plug anything else into the power meter? I use it from time to time and gives reasonable readings, raspberry pi 4watts, hp printer soft off 10 watts, speakers, desk lamps, washing machines etc. Can you cross check this? the meter is this: http://www.chacon.be/media/sync/54355/From%20Chacon/54355%20User%20Manual%20EN%20%28old%29.pdf Thanks for your time.

ThermalMike Posted March 2, 2015 Report Share Posted March 2, 2015 Hello, Did you try testing after a period of time when the PSU was off to confirm? Power can still hang inside the PSU caps for a while and this could be the cause. Just try testing it after the PSU is off for a while and see.

Tt Andy Posted March 4, 2015 Report Share Posted March 4, 2015 Mikes right, the power can linger inside the capacitor for some time. Try turning off your computer, unplug the power and press the power on button on your case, this usually helps to get rid of the remaining power stored ThermalMike 1 Quote Link to comment Share on other sites More sharing options...
