How Do You Measure Wattage Usage?

char[] rager · Dec 19, 2010, 03:34 PM

I would like to know how much electricity my PC is using. Is this what you guys use? Or should I get something else? I am looking for something that will display in real time.

Yeah, Kill a watt is good, but you might want to find cheaper alternatives.

95Viper · Dec 19, 2010, 03:36 PM

Yep, that is one way; and, the safest for a normal consumer.

char[] rager · Dec 19, 2010, 03:43 PM

Will it be able to handle the current and wattage going to the power supply?

95Viper · Dec 19, 2010, 03:48 PM

That one goes to 15 amps and 120AC. As long as you don't exceed the specs of that, sure.

If you are on a circuit of greater current and/or voltage, you might need a different one or use a different testing method.

Well I was reading the AC input on my PSU and it says "100-240 V, 15-9 A, 60-50 Hz."

If your computer is pulling 1800w blowing a kill-a-watt is the least of your concerns.

Try local Cooling

That 100-240VAC is, because it can adjust(sometimes on it's own or manually, with a switch) to the variations in voltage; and geographical use of different delivery systems. Some places don't use 110\120 that we in the States use.

The Current 9A to 15A is, just, stating the thresholds for usage. Probably, under 9A it won't start\regulate and over 15A, it will blow a fuse or trip the circuit off.

PSU needs a lot of leeway for all the differences they encounter.

Actually, @ 100 volts, it will pull 15 amps, and 240 volts will pull 9 amps (max safe load for the psu). I use a device from northern tool. Called a watt meter, or amp meter. Not too fancy, doesn't do any logging, but its cheap and accurate. It will measure the load of cellphone chargers.

Kill a watt like others said and some APCs like Cyberpower do some and some fan controllers that have like the Zalma ZM-MFC2.
