There are online energy calculators available on the internet such as the Extreme power supply calculator. All you have to do is punch in the detailed configuration of your PC or laptop and click the calculate button. The aggregate of power consumed by all the components is displayed.

omg its nlm likes this.

Tells me my PC uses 621W Seems I may need to upgrade my PSU soon. Thats a bit close to its 650W maximum output.

Mine's at 410W

So I'm good with my 600W PSU.

I use my Uninteruptible Power Supplies to inform me how much power my computers draw.

Well mine comes out at about 300W - well below my maximum. These calculators always come out way below what I expect (esp. this time with the 9800GTX!), I wonder if I'm forgetting about something!

It still annoys me that they refer to current as 'amperage' though

The American Heritage® Science Dictionary

E=I/R

E = Voltage Volts
I = Amperage (amps)
R = Resistance (Ohms)

Amperage is current

http://www.wisegeek.com/what-is-amperage.htm

The Ampere is a unit of current. The term amperage is looking for current expressed in amperes.
Current can also be expressed in coulombs per second, which is what Amperes are.
Volts are expressed in Joules per coulomb.

The power supplied to the USB drives isn't necessarily dependent on the power supply. The USB specifications, plus the motherboard really determine that. After all, those thin circuit board traces can only take so much amperage before they burn up, so the USB specifications are there to limit the maximum each USB port is supposed to supply, and it's up to the chipset/motherboard manufacturer to implement it to specifications.

Which is why some high-power USB devices will have a dual USB dongle so you can draw power from two USB ports instead of just one.

124 watts is what my old system (not what I have in my sig) is drawing through my UPS.
