I realy need help with power consuption..

[Artas1984]

Electricity bills are roof-breaking and i am trying to find the cause.

What disturbs me most are the ridiculously mismatching numbers between Cooler Master power calculator (or any other for that matter) and Legitreviews Core i7 5775C review.

Let's say i don't use my GTX780 Ti GHz Edition. Then my PC setup is basically like the one in the review right here:

http://www.legitreviews.com/intel-core-i7-5775c-broadwell-processor-review_166875/16

I have a 7200 rpm HDD, a SSD, Z97-K motherboard, 3X 140 mm fans connected to motherboard, 2X8 GB DDR3 and Core i7 5775C, which runs at 800 MHz while i am browsing the web.

According to the Cooler master power calculator i am drawing 117 W at idle if i insert the written specs and numbers and set CPU speed there at 800 MHz, which must be some kind of nonsense, because according to Legitreviews chart "total system power consumption" a system like my draws 26 W at idle.

What the hell in wrong with this 117 W VS 26 W picture?

And now the best part: GTX780 Ti GHz Edition! According to w1zzard, in his stock GTX780 Ti review, that video card draws a mere 10 W at idle!!!

Please tell me, w1zzard, or any who can speak in his name, are those 10 W of GTX780 Ti were measured when the card was idling 324 MHz core and 162 MHz GDDR5?

If so, how much power should my system be drawing in reality when CPU is at 800 MHz and VGA is at 324 MHz core and 162 MHz GDDR5?

If i insert my full load in the Cooler Master chart, with CPU at 3300 MHz and VGA at 1150 MHz core and 1750 MHz GDDR5, i am getting 500 W system power draw!!!

Best thing to do is measure your power consumption directly....different systems will pull different loads. Charts can be a guide but will be more of an assumption. Different programs stress to different levels, bugs or driver issues can drive consumption up, overclocking can make a substantial power consumption increase, etc.

Measure your own consumption and you'll have better answers as to what your system is consuming and when: https://www.amazon.com/dp/B00009MDBU/?tag=tec06d-20

Or you can run a UPS to filter the power to your PC and allow it time to shut down in the event of a power outage to prevent corruption. The Kill-a-watt is cheaper though.

While I can confirm low idle on my 980Ti in comparison to W1z's reviews I cannot vouch for the 780, though his testing is very consistent and thorough so I have no doubts there.

Calculators are notoriously off my man... don't use those to compare anything.

Get a watt meter.

As far as W1z's reviews, that 10W idle would obviously be with the clocks in idle.

Regarding what you "should" be pulling.. who knows as every system is different. I would venture a GUESS to say on idle you should be around 80W give or take like 20W. There are so many factors that it really depends on to give you a straight answer, its tough to be accurate like that.

I highly doubt this PC is "roof breaking" your electricity bill... do the math with your cost /KWh and see how much it costs to run 117W per hour/day/month. You will be surprised

Really, your problem lay with how you are trying to get power readings and comparing them. Get a KillAWatt man and stop comparing apples and red playground balls.

Coolermaster is probably closer to the truth,. although I suspect you are actually running at least 140w(max) at idle. Legitreviews either made a mistake or they are using some kind of weird hibernation rating for idle.

If I am understanding the premise of your question. You are not spending much on electricity from the PC.

Your system sounds like it would idle around 75-90w, depends on how many fans \ drives are installed, but as a example mine runs 80-94w while i was typing this.

At full whack i would of thought about 300w while gaming, which will depend on game and if you use vSync or not.

If electric usage is a real concern look in to the newer type light bulbs do not keep opening the fridge\freezer doors and wipe the seal with a cloth to make sure the seal is good. Depending were your from maybe some thing like a Kill A Watt if you can get one and test stuff in your house.

A UPS would give you a fair power usage but is the more expensive although you should have one with a PC anyways. You could look in to power strips to here there is a company in the US called TrickleStar that turn off those pesty vampire devices while stuff is not in use, here's a link

EDIT: I forgot to say Air conditioners will take up loads of power in a house hold, which can add 30$ + to a electric bill easy.

Power calculators are used to find a theoretical peak maximum power draw for the entire system (with all components at max load), so the buyer can select appropriate PSU model.
You are on the right track though, you know exactly how much power your cpu and gpu are sipping at idle (26W + 10W) ... add 6 watts for 2 sticks of ddr4 ram, 5 watts per hdd and 0.5 watts per ssd ... and multiply the total by 1.25 for 80% psu efficiency around idle power levels. I'd say no less than 60W at wall with zero load ... and I forgot the fans.

yeah agree with that, online calculator just giving you the range that your system may draw.

and you say the bill, is that from your computer only? you ON it 24/7?
no AC, refrigerator, electric something, tv or anything?
