Well with just the power cord plugged into the PSU it draws 44W, nothing plugged in on the computer side. When I turn the power button to OFF it draws 0W  Is this normal consumption? Whether I'm high. Thank you

    Hmm. Yes, that does seem high with nothing connected to the psu. Hopefully some other 750w g3 owners will chime in.

    I sent a PSU on a complaint. I got new ones. The situation is the same. I turn off the PSU after I turn off the PC.

    What are you using to determine the power draw?

    Registered just to report the same issue. My Watt-meter registers it to 46 Watt just as soon as PSU is plugged in without anything plugged into the PSU. (And yes my watt-meter checks out. I can measure down to a single watt consumption).
    This is extremely disappointing and a disgrace that machines with this PSU the world over are drawing ~45 watts doing absolutely nothing.
    What an environmental travesty.

    I did some further tests and it seems the PSU is quite alright. Here's why:
     
    Some cheap/older/etc. Watt-meters will actually report a wrong wattage when the current drops lower than they support.
    Should you see these crazy standby numbers on your device, then connect a power strip to your watt-meter and then a lamp in the power strip.
    Measure the lamps consumption. - keep it on - And then connect whichever device you need to measure and get the new devices consumption by doing the math.
     
    I connected a power strip to the watt-meter. Added an LED lamp that consumed 9 watt, and adding the PSU then didn't add to the number.
     
    If you're seeing standby numbers like this it likely means that your watt-meter is unable to measure low enough current.
