It can measure the Amps, Volts, Watts and more. It is real time measurement, so as I crank up the CPU usages, it will show the Amps going up on the stop. I definitely recommend you get one from amazon or other place to measure your electronics. When you see the numbers, you will be more encourage to save up the energy. I used to leave all my computers on before, now I turn off everything when not using. Hi Bryan,

I personally want to check my computer too. Since I'm not a techno-engineer, I don't even know if there is a tool to check it. Hi,

Whenever I looked at client's server utilizations, they are not even using 30% of their cpu/memory. There is the problem of single point failure when using a mini but in a server rack environments, hardware failure rates are lower compared to a laptop and home PC. I currently have a half dozen of Minis in my server rack for exact reason. My friends and clients love the quality and simplicity. For the same reason, I will be starting Mac Mini targeted service provider.(hopefully soon) You are exactly right.

I've moved from multiple Dell mini tower boxes as servers to the new Mac Mini Servers. The Dell's pull about 200 watts at idle. The Mac Mini pulls about 13 in typical server usage, peaking at about 15 watts. My router pulls about 3x that. PG&E runs about 25 cents/watt. That means approximately $405 in savings for the year, per converted server. If you're doing web services, a Core 2 Duo at 2.53GHz has more than enough oomph to saturate a 100 mbit/s connection. I thought Mac's were supposed to be expensive! Just in terms of power usage, the typical 1U/2U server would be best replaced by a Mac Mini Server. Thanks for the actual measurements.

It lacks the power and the expandability, but people love them for their design and usability. I haven't even thought about running a game on it, but it is currently powering my dual 24inch monitors. My first intel Mac Mini's fan went crazy when I used it with one 24inch monitor. Mini's graphic has improved dramatically since it's first released, but it is still laptop based hardware. What about getting a Mini and use it as your main computer to do all the work. Use the gaming machine only when you need to. You will save your money on both Power consumption of the machines and Air Conditioning. Mac Mini is very interesting little machine.

I dont own a Mac Pro, but i own a QuadCore 3Ghz Hackintosh with 8GB RAM, SSD drive, 3TB HDDs and powerful gfx card. Power comsumption around 150-200 Watts without my 2x monitors. Thats roughly 120Watts less than a mac mini which in my country is atleast 200 EUR (about 250USD) extra for power consumption. (if you run it 24/7) As i am only a software developer, thats 250 USD i could easily safe each year as i dont really need more than a Core2Duo 2,53Ghz as the mini offers. Also as i want to purchase another mini to act as a home server together with a good nas, overall power consumption of all 3 devices would be less than 100Watts, with the current hardware it would be well over 200 Watts. The only downside is that i would still need to keep the pc to play some games from time to time so i wouldnt get any money back and the 500 spend on a mini would need some time to be saved with power... So i cant really decide, as my PC runs approx. 15 hours a day the difference in power consumption costs wouldnt be too much, maybe 100-150 EUR a year which is 8-12 EUR a month. If id sell the PC for a mini, savings would be immediate, but then again the mini cant play games very well To be honest, thats the same thing i thought about lately.
