Is there a way to know the Electrical Power consumed by a Power Supply without opening the Computer Case?

Dear all,





First of all, good afternoon. Secondly, I would like to know if there is a way to identify the electrical power consumed by a power supply without having to open the computer case. Any help is greatly appreciated. Thanks!!

You can measure how much electricity your computer is drawing from the AC wall outlet by using a Kill-A-Watt meter: http://www.amazon.com/s/ref=nb_ss_gw?url鈥?/a>





No cable cutting necessary. Plug the Kill-a-watt meter into your wall outlet, plug your PC into the Kill-a-watt meter. Done.Is there a way to know the Electrical Power consumed by a Power Supply without opening the Computer Case?
use a multimeter to measure amps being pulled by the power supply. The problem is that the measurement requires the meter be in series which mean you will have to cut AC cords hot and shunt it with meter. You can also use an ammeter that employs an inductance loop but again the AC cords outer insulation must be stripped and the induction loop must be place around the hot. After obtaining the amp being pulled, the wattage of the supply will be the product of the current (amps) and the voltage (volts) i.e. Power (watts) = I (amps) * E (volts) or if you find this method inconvenient or beyond your ability buy a commercially available metering device. Here is the URL of a company I have dealt with - %26gt; http://www.powermeterstore.com/index.php鈥?/a>
there are some devices you can buy that will tell you exactly how much power something is consuming. Basically plug the cable into this device and this device plugs in the power outlet.
