Good Watt Meter Needed

[AMD FTW]

Anyone know of a good watt meter that I can leave plugged in constantly that can handle 20 amps. I have gone through 2 of these kill a watt units and my rig only pull like 1600w and these are suppose to be good for 1875 watts. My first watt meter died, this one currently still works but being that the plastic is so discolored from the heat makes me not want to currently use it.

Found the source of your problem



On a serious note, avoid chinese things, they are of very very low quality.

Fluke has some of the best test equipment available... but its pricey.

A clamp meter will be better for what you are trying to do. I have not checked on what brands are good lately but as an example : http://www.amazon.com/Greenlee-CM-450-Clamp--Meter-True/dp/B002COQGI2/ref=sr_1_5?ie=UTF8&qid=1366180843&sr=8-5&keywords=clamp+on+meter

Than you will need something like this to seperate the lines in order for the clamp meter to work: http://www.amazon.com/Tekpower-M920-AC-Line-Splitter/dp/B003A0MD48/ref=pd_sim_hi_2

I've had use for these many times over the years.  Unfortunately the Kill-a-watt is the only affordable option for instantaneous V/A/PF readings (e.g. wattage).  You may try splitting your main power line into a Y with 2 receptacle plugs.  Be sure to keep lengths similar after the Y.  Then just run 2 wattmeters and total both power readings (won't be exactly the same on each, but will get you below frying).

I've used a Brand Electronics meter for years that's worked pretty well (don't think the kill a watt was available at the time I got it).

It's a little expensive, though.
