You guys here are into electronics,so i'm just gonna assume i am in the right section of the forum.
I need help on calculating electric power consumption (kWh - kilowatts per hour) on my PC.
The reason is that i will be using my pc as a server for one month. That means 720 hours, total time in witch I will be not turning of my computer. So how much kW my pc will be consuming? I will do the rest of the math, to find out how much money i need to pay at the end of the month.
Since I have no idea what so ever how to calculate this i will post here some pictures,and give you guys some info.
I will be using my PC to run server for a video game.So the game will be running in the background wile players log on and off.No idea what that means for my pc,and how much that will stress it,but i did these readings of the printscreens i am about to show you while running in the background:uTorrent, Assassin's Creed Liberation HD, Google Chrome,Picasa, Photoshop CS5. I don't know if I did well by runing AC Liberation i just wanted to get some high readings on my voltages.

How much work will it be doing because if you have it sitting in idle it only pull around 70W. BTW servers don't need GPUs so once you set it up up you can turn them off.
 
I just did some research on this website http://www.extreme.outervision.com/PSUEngine and it tells me,that I need a
Minimum PSU Wattage:194 W

I have a 600W psu,so no problem there.
buildzoid, you said 70w.....per hour or per day ? or per month ? I am a bit confused.
I don't know how much work it will be doing. I expect around a maximum of 100 players to be on the server. An average of 30 every minute. Other then that....i will be using the computer to browse the web for maybe 2 hours a day using google chrome and that is pretty much it.
But i am afraid to do much browsing since i don't wanna cause any lag...so i wanna leave my internet bandwidth free as much as possible.
Btw this is my internet reading.

70W means 70J per second. 1kWh is 3 600 000J. So if your PC pulls 244W at 100% load it will consume 244J per second so in a month which is 2 678 400 seconds (24x31x3600) your PC will consume 653 529 600J so about that's 181kWh in a month. This is simple high school physics the only reason why people have a problem with it is that power companies charge for kWh instead of Joules. A watt is a measure of energy(J) per second a kilo watt hour is 1000 hours of joules per second(which is a completely stupid way of saying 3 600 000J).
 
Thank you buildzoid for the input! You were very convincing. Anybody else,got other answer? suggestions...
Any thoughts on the bandwidth that i have and if it will sustain 100 players at one time?
Also,should I change to Windows Server 2012 R2 or to just keep using the same Win 7 ? As i did research Win 7 is pretty much same as win server.

Stick to win7, server only has some extra features that aren't much use for hosting game servers since they are targeted at businesses. As for bandwidth I'd say you're good to go I have a friend who host 2 45 man Minecraft and a 10 man teamspeak server off a similarly fast connection and has 0 issues with speed.
 
for me when i calculate power cost (and the price per KwH is .114477 dollars) i just measure the power consumed with a power meter (the cheap belkin one, or a watts-up meter etc) and that is how much it costs per year.

lets see 24h in a day, 7 days in a week, 52 weeks a years for 8736 hours in a year.
my mythtv server idles at around 36 watts. so it will take ~27.8 hours to use a KwH, so if i divide ~27.8 into 8736 and get about 314.496 and that mulipled by the KwH cost(.114477) is 36 dollars per year for the computer to idle. (i only have it on for 8 hours so it really is third that. but because it uses about 57 watts when doing useful work (tv recording and scanning commercials ) it costs more to run...


This method of power cost as the instantaneous power measurement to run per year only works if the power cost is around $.11-$.12 (.114477) a kilowatt hour (and if the power consumption is static).

so the formula is per year (8736 divided by the KwH used times the power cost) but if you pay $.114477 a KwH the cost per year is the Watt used in Dollars.

BTW, there other charges beside power cost such as the "delivery charge" so the "real" charge for KwH is between 5.5 to 9.9 cents an hour depending on the time of day but to make things real simple and realistic i use the power bill cost divided by the KwH's used.
 
you should not do torrents when you host a game server , but can surf or download files .
for the power estimation and monitoring , hwinfo can show the info if you have an ups connected to the pc by usb

have a look above the Start button
 
just get a $15 mains power meter and measure it. You'll never be able to guess accurately as different parts of the system will be stressed differently and unpredictably. The time you waste calculating it inaccurately would be better put to purchasing a power meter.
 
If you want to save a few pennies on a wattmeter, consider getting one from Ebay or so.
 
buy a cheap wall meter. you can never be sure by estimates, i've made a thread where people are comparing results and it really is unpredictable.

your specs arent too high so i'd say <200W at load and <120W at idle (possibly a lot less), but the efficiency of your PSU really matters here.



oh and to understand your power consumption: one watt is one joule per second. so when we say "200W" that means per second.

you are charged per kilowatt hour - so 1000W per hour. if your PC used 250W and ran that for an hour, you'd get charged one quarter of your kw/h rate.
 
Mussels is correct on this. On a side-note: my renovated setup idles at around 40 watts. Yay for mATX and a 80Plus Gold rated PSU!
