Anyone know where I can buy a Smarthome EM100 energy meter or similar product in Canada.

for the price, you cant beat those. as long as you dont need a unit that is very accurate. a couple watts more or less.

nice that's the newer one. i think i got the 3000 model.

good thing is that you actually realize,overtime, how much a certain appliance will eat up even if its not in use.then you end up buying power bars in bulk and happen to protect said appliances at the same time.

I have both the Kill-A-Watt and the Blue Planet one from Canadian Tire. The Canadian Tire one is much more accurate and based off of a much sturdier design from UPM.

My System Specs

Default Fun with a Power Energy Meter

I was curious about how much greater efficiency/savings (if at all) a newer 80+ PS would deliver, so I picked up an OCZ Z-Series 650w 80+ SILVER (advertised as up to 88%) and compared it to my older SilverStone ST60F - 600w (advertised as 75%).

Overall I was impressed and a quite surprised by the degree of difference, especially when idle or folding. I checked the folding results several times as that what the system is usually doing and the difference was dramatic. I expected less and suspect my ST60F may be less efficient than its specified 75%.

P.S. While measurements were repeated in all cases, the results are not scientific, …but interesting. I did make sure that the CPU was locked (stepping was off) and that GPU step down did occur during idle, Prime95 and Folding measurements.
Btw, PF with the ST60F was 98% and the OCZ-Z slightly less at 96%.

cheers

Here is a breakdown of the wall power readings in watts that I measured with a UPM EM130 (borrowed):

80+ is the way to go.

You didn't test CPU + GPU folding?
