power consumption of specific peripherals (HDD, monitor, etc.) 1

[czarcoma]

good day,

--- would just like to ask if anyone knows a good resource that lists the power consumptions of specific peripherals? (hubs, routers, HDD [external/internal], monitors from 15" to 17" [lcd/crt], etc.)

--- am trying to compute the average consumption of all IT equipment in our company. manually testing each equipment will take to much time.

--- hope you guys can help me out on this one.

regards.....

You should be able to google that with good results.
Tomshardware or techrepublic may have that info.

This might be one way. You go to the power supply needs.

Now this one is slightly off-topic but look at the pie chart!

To find out the power consumption of the entire server room, you would need a snap-on amp meter, amps times voltage would give a close wattage. Each circuit feeding the room would need to be calculated. Electricians could easily do this, and should have the amp meters. I have a multimeter with an current meter, but it takes too long to calculate individual devices. Lists of devices are only estimates. With a n amp meter it should take about 5 minutest per circuit, if the readings are taken at the circuit box.

I would try measuring the actual power consumption of several representative systems using something like this inexpensive power meter:

and then extrapolate total power consumption from this data.

With an Amp meter you do not have to turn off any devices to use it, they clamp onto (surround) the wires for testing.

--- many thanks guys! didn't expect to get replies this quick. TEK-TIPS rule!!!

--- don't have time to check out all your resources just yet (due to regular everyday sysad activities). but will give you feedback on yur resources later.

> just have a question to technome...
do you clamp the AMP meter on just one "leg" or "prong" of the power cable or on the whole cable?

--- again. many thanks guys!

With a clamp on ammeter you would have to isolate the power leads and clamp on only one wire.

If you are looking to measure only relatively low power 115VAC devices like PC's, switches, etc and you can afford to interupt the power to them, the gizmo I mentioned from Cyberguys above should work great. You just plug your device directly into the power monitor and get a real time digital readout of power consumption.

Goes around one leg of the cable. If at the box and the circuit is 120/240 you need to check both legs. And if 120 volt only you can measure it on the leg or the neutral.

You can also get an adapter that goes with the probe that plugs between the source and destination at the wall plug that multiplies the reading by 10 to increase accuracy for those items that use so little that measuring is difficult.

For future planning you might want to consider assigning the highest value you encounter to the requirements for all. Lots easier to overestimate the need than to underestimate it.
