PSU overload or dying?

[MattKier]

Hello there.

I'm looking for an absolute genius who can tell me if this bad or not.
On Jan. 17th 2023 my computer used 6,8 KWh that day which is absolutely insane.

It's on for 12 hours everyday but not once has it come up above 5 KWh. It varies but it uses roughly 4,3 KWh a day which still seems high to me.
So maybe now you can understand my confusion.

I have 3 HDD's and two m.2's as my storage. Wattage unknown.
1 GPU (Asus) GeForce 1070TI which runs at 172 watts according to the internet.
I have i7-9700K (not overclocked) which runs at 95 watts
1 USB 3.0 PCI-E (wattage unknown)
1 NZXT Kraken X61 280mm liquid cooler that usages 7,2 watts
And lastly I have various things plugged into my usb slots on the computer but that shouldn't usage that much power + 4 fans in the case (besides the two 140mm on my CPU cooler)

My powersupply is a EVGA SuperNOVA 650W which I have used since 2015.

Is it time to consider getting a new PSU or are things running the way it should?

How are you measuring the power consumption?

 

What are you doing with the PC during the 12 hours? Is the PC under constant heavy load or is it spending most of the day idle?

I had a thingy thing that measures wattage and KWh in my wall socket where the pc was connected to. I don't have it anymore so can't give more specific information
As for the load it varies. I hardly game anymore but it does happen so the load is minimal mostly. I work as a music producer and my program tells me the cpu is running at minimum load. I'd say 8 hours under load (not heavy though) and 4 hours somewhat idle

Were there any other devices plugged in to the power meter, such as PC monitors, speakers, or any other appliances? 6.8KWh for that system in a single day would be very high, let alone for only 12 hours with only moderate load on the system.

Usually assume around 10-15W per HDD. M.2 SSDs are much lower, typically around 5W while actively writing to the drive but often less than 0.05W when idle.

 

Under a heavy load (such as gaming) your system would likely use less than 300W. With efficiency losses from the power supply would be around 330W max. 330W over a period of 12 hours is only 4KWh. Unless you had some other appliances plugged in to the power meter I don't see any way you could have consumed 6.8KWh from that system alone in a 12 hour period.

If you also had your monitors plugged in to the same power meter check how much power the monitors use and add that in to the equation.

A hard drive is more like 6-10 watts. 

M.2 SSDs are like 1-2 watts when reading, under half a watt idling, maybe 5-10 watts when writing a lot of data. 

Give your 9700w  100w and your video card 175w 

2-3 per stick of ram, the cooler and other fans in your system maybe 10w in total. 

 

A monitor consumes maybe 40-60w depends on resolution, how bright you keep it...   5.1 speakers can consume 50-100w if they're older class AB amplifiers in it (my logitech 5.1 consumes 40w+ even at low volumes)

 

Thing is if all's configured right, your CPU should idle at under 10-20w when you're just in Windows, browsing youtube, all that, and basically it should automatically lower frequency of some cores etc etc 

If you set the overclocking so that all cores are kept all the time at that frequency, I can see higher idle power consumption

 

Same with the video card, in Youtube, while watching movies, the card will only consume 15-30w 

Even in games, a game won't keep the cpu cores running at 100% all the time, so the average power consumption should be lower than 90-100w on the cpu.

 

It could be you have a mining virus or something that keeps your video card running in the background all the time, but even so, your computer shouldn't consume more than 250-300w, making for around 3.5 kWh over 12 hours, if you're gaming all the time. Use HWInfo and look at power consumption of the cpu and video card, use Task Manager (see what applications put load on video card, see video card usage when you're out of games)

 

Maybe the power meter is wrong, or maybe for some reason the power factor correction doesn't work in your power supply and the meter is measuring the reactive power instead of real (consumed) power or something like that.

There totally was monitors and pc speakers connected as well.. I forgot about that.. Whoops. But that still doesnt explain the 2,5KWh spike from all other days over the last year.
My whole 2 bedroom apartment uses 4,6KWh on a normal day so that means my pc is guilty of almost swallowing 100% of that.. That's insane! Stuff to think about.
Appreciate the info about wattage on HDD's though! As mariushm said below you I could have been using a faulty measuring thingy or I read it wrong.. Something is for sure not adding up though

I use 1080p res on my monitors and they are both very power efficient.. I can't find the wattage right now but your 40w estimate sounds about right.
I have come to the conclusion that I MUST have read my meter wrong because my whole apartment uses 4,6KWh and that 2,5KWh or whatever spike should not be possible.. But stuff to think about in these dark times.. Can't believe my pc uses that much power.. Bit of an eye opener! I will try to use HWinfo for a time to see if anything changes! thanks for the suggestion
