How much power does your NAS use?

Well my 'nas', well server would be more accurate is currently using 86w (according to the ups and nuts software), can usually get it idling down to around just under 70w when my hard drives spin down and just my 2x nvme active. Highest I think I've seen is around 180w when it's doing stuff and all drives active.

I am trying to get it lower when idle though....

Unraid i5 13500, 96gb ram (bought before the current pricing, I didn't win the lottery lol) , 12x18tb drives + 4 sata ssd on lsi 9300 16i, 4xm2 sata, and 2x nvme from motherboard.
 
24.5 watt idle at the wall on a kilowatt meter with all 4 HDDs span down.

Unraid server specs:
8th gen i3 8100 4 core with quick sync.
No dedicated GPU.
16gb ram.
2 x nvme in a cache pool.
Connected to a small ups which gives about 90 mins run time then auto shuts down on power outage. Showing 125 days uptime.
 
Not a NAS but I've added a Dell QBM1250 to my setup which will take on some NAS duties though not its main purpose - with stock settings and balanced power profile in Windows 11 it averages 11 watt when (truly) idle at the wall:

Intel Core Ultra 265, 32GB 5600MT, 1TB NVME and additional USB4 module.

Which is pretty impressive - though over a longer time period it is a bit higher if you include the background Windows services which annoyingly kick in from time to time - but those will be disabled when it is running normally.
 
OEM NAS is hard to beat. My house typically draws 90-110W as base load with ~10 devices running 24/7 including IP Cameras, switches, router, wifi extender, smart plugs, TVs (in standby) etc.

During winter my heat pump alone will draw 500-600W up to 10 hours per day so puts that lot in perspective.

When you get down to sub 50 watts you really have to start questioning the accuracy of the readings. At that point you’d need calibrated equipment and piercing probs to have any level certainty in the numbers. 5 watts simply isn’t possible with any off the shelf PSU.

The standard Killowatt style plug in power meters are very accurate to plus or minus 0.1 watts. I have seen the same with smart plugs with built in monitoring. Not sure why 50 watts or under is significant.

Jigger is incapable of changing their opinion after the first time they read information on something - even when there has been significant progress since. Years back it used to be true that cheap mains energy monitors were generally pretty sucky outside the 100s of watt range or above but as per the exhaustive study I linked them to awhile back there are plenty of consumer devices now that are accurate to 3-5% above 1 watt and some even better than that.

EDIT: I'll caveat that - Amongst other stuff I have a Tapo plug that is accurate enough as makes no odds when compared to industrial standard equipment but someone on Reddit tested a large number of them and found around 20% have pretty whacky calibration for some reason, despite the other 80% being within 3% accuracy.

I’ve already pointed out way that’s not the case.

Well you didn't. You just said they weren't accurate under 50 watts because they aren't... i.e. because you said they aren't.

I'll counter that with they are mostly fine. YouTube vids support this.

Well I did, and I’ll point out anyone can make a video. If you have faith in accuracy of these cheap power monitors that’s fine, but all are out of spec in the UK and non are calibrated… further, the two I’ve used both read differently to each other and neither match a known load.

There are plenty of people who've done tests against known accurate equipment for example https://techenclave.com/t/smart-plug/271059/6 and the case study, specifically intended for scientific merit in data acquisition https://www.sciencedirect.com/science/article/pii/S2772671123000323 I linked you to before, along with a whole range of YT videos from casual/amateur efforts through to people who have an established name in the industry.

While for scientific data acquisition they can be dodgy there are plenty of consumer energy monitoring devices which are as accurate as makes no difference through the range from single digit low load through to high kilowatt loads.

The metrology and device come into question. It’s foolish to argue the case of accuracy of these cheap Chinese made devices. That’s just a matter of fact.

Clearly you haven’t read your own links or managed to keep context in mind.

You do talk some utter rubbish - the links even have pictures and comprehensively demonstrate you are wrong... what context? as shown in the links even cheap energy meters can be as accurate as makes no difference through both low and high load ranges.

You do. I remember your 9 watt power use claims. The illegal scanning electron microscope operated at your home. Numerous claims of access to internal Intel data etc.

Anyway if you want believe your £10 power meter is accurate that’s fine but the reality is different.
 
What would you have people do to measure and contribute to threads like this who are measuring power usage at home then @jigger ? Hire a specialist company with specialist equipment? People discuss power usage on the internet all the time and I don't see many people take issue with them just stating a usage amount to add to the discussion. I've never seen a big debate as to the accuracy of the power meters used being an issue.

If we are talking the measuring of between zero to a few watts, then fairly obviously, something more high end and designed for that range would be better yes, of course. But for basic comparisons around the home, most stuff is accurate enough for it to be a non issue.

My server idles at 24.5 watt on a killowatt meter, 25 watts reported on my Octopus smart app and 24.8 watts on my smart plug with energy monitoring built in.

Why are you getting bent out of shape about the accuracy of stuff under 50 watts? That's such a random number to pick.

I’m not bent out of shape, if you want to believe a £10 Chinese made power meter from Amazon is accurate that’s fine, but it’s not.

Funny you are so hung up on that most of which wasn't me talking rubbish just like this instance, aside from making a mistake on the type of microscope but which you are misrepresenting what I said as per the last time you dug it up - I said something like: "its a high end non-optical, specialized microscope I don't know the exact details - but I belive its some type of electron scope".

(Funny thing is you always think I'm BSing but here for example is a picture of my dad in his lab with Gary Lineker heh

Hence why because of his job/specialisation he had industrial grade equipment at home.
)

PS I didn't say any old £10 energy meter is accurate but contrary to your insistence there are cheap ones on the market which are close enough it makes no odds in these kinds of topics which I've backed up with some evidence of which there is plenty out there. It isn't like years ago when cheap ones were pretty garbage outside of the ~100-1000 watt range.

I’m not the one making attacks. You claimed to have an unlicensed nuclear electron microscope just laying around the house. to back another false argument… When pressed over this lie, you couldn’t even provide a model or even brand. It’s you that talks nonsense.

Only I didn't, I incidentally mentioned an electron microscope (mistakenly) in a wider context not a specific claim and when queried I said I didn't know the details. And I was asked for model of electronic analyser used which I provided.

I can't believe you are still hung up on and misrepresenting something which was what 20 years ago?
