Software to see Watts Used for PC?

Is there a reliable piece of software that can show power wattage used as the PC is running?

I don't think software will ever be accurate with something like that. The only thing that will really be accurate is a hardware monitor I believe.

Laptop | 2018 MBA 256/16GB | MX Master

I am thinking since all components go through the MB, maybe a hardware monitor (as software) can give a good estimate rather than a theoretical calculator?

You probably want a specialized device that plugs into the power outlet, and has a output on it for the PC to plug into. A screen on the device will display the current power draw, in W, to indicate how much electricity you are using.

It would provide a very rough estimate probably. The most accurate way would be to use a electricity usage monitior (search it up) and measure the watts it is taking from the wall.

 

My personal recommendation for a electrical usage monitor is the p3 kill-a-watt

Also, if you have a "smart" power supply, like the NZXT’s E Series, or Corsair’s HXi they could tell you the watts it pulls. 

 

I have also heard of the Joulemeter by Microsoft. Might be worth a look

All components don't go through the motherboard. You'd be off by the efficiency of the power supply at least. You'd need to measure at the plug, wall or internally within the power supply. If you wanted to do it via software, you would need to have a power supply which supports that which AFAIK from googling it a minute ago I found NZXT has a Seasonic based power supply that offers it.

Otherwise, there's a couple power supplies which have screens on the side like the Asus ROG power supply.

 

Or you could buy a Kill-A-Watt.

I got a watt meter for $16 off Newegg, worth the buy, especially because component power draw isn't as important as draw from the wall.

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

How many watts do I need? ATX 3.0 & PCIe 5.0 spec, PSU misconceptions, protections explained, group reg is bad

Get a UPS ;) Battery backup and will tell you how many watts you drawing.

If you're interested in a product please download and read the manual first.

Don't forget to tag or quote in your reply if you want me to know you've answered or have another question.

It depends on the motherboard.  Some boards are accurately read with software.

Just out of pure interest, which boards are you referring to. I do not know of any motherboards with a energy consumption measurer.

The Crosshair VII has been shown to be accurate with software.  I wanna say someone tested the X470 Prime Pro and it was accurate too.
