How to find amps or watts

post #1 of 6
Thread Starter 
I'd like to find out how many amps or watts my graphics card is currently using. I know how many volts the gpu and memory are using, but I want to know about the amperage. I have a multimeter that will find amps, but I don't know where to put the two ends. It's a 7800gs agp. I figure if you can help me find the wattage, I can find the amperage from there by dividing by 12.

Check under the voltmods section for where to take readings.

For conversion, just use: Power(w) = Current(i) * voltage (v)

I know the mathematics of it. Problem is I can't find the current or the power. I'll check the vmods section.

To measure current, you need to measure in series. You can't do that with a multimeter. You need to get a clamp amp-meter and I don't think they make one for small circuitry.
