Should the Watts always be the same? - Page 3

post #21 of 24
Mine stays at 147 watts all the time idle or at 100% load

TwoCables, you could have been heavily gaming during the brownout and still been fine. Why? Because your computer and monitor use switching powersupplies. Usually in a brownout they lower the voltage to 100V from 120V, which significantly reduces the amount of power that a lot of devices use (IE a lightbulb that uses 100W at 120V will only use around 60% as much power at 100V). However since your computer uses a switching power supply it will simply increase the current to maintain the same power level. IE, if it was drawing 2A at 120V it will draw 2.4 A at 100V in order to maintain the same power usage. In fact, your computer actually uses more power during a brownout as lower input voltage makes it more inefficient.

So if your PSU has for example 85% tipical efficiency (for that amount of load on PSU) then real system`s PWR comumption is 527 x 85/100 = 448W ...

And OP you have 6core CPU so what did you expect??

My Q9550 @ 3.9GHz pulls around 150W under full load

CHEERS..
Even though we only need to be concerned about the draw from the wall in this particular situation, I still want to point out one thing:

Instead of multiplying 527 by 85 and then dividing by 100, you can just multiply 527 by .85.

I'm speechless. So, I'll just keep it simple:

Thank you for teaching this to me!!

don't trust software for your wattage, go by a wattage meter.
