how did you get 500w of idle use. that does not make sense. could you please post your table. i have my pc all the time on and some other things and not even close to that.

Agree, 500w of nothing is INSANE in 2022 are you sure. Please list brands.

  I don't think it's any one thing that's 500W, it's an accumulation of many devices all doing 20-100W. Lots of modern PCs are 30W+ even when off— like not even on sleep, but on off/standby. So these numbers don't surprise me in the slightest.

    i worked for a electricity meter maker and measured consumption for things in my house and have now meters on most sockets and so on. 500w idle is huge.

      How much is the draw of all those ammeters? i.e. the "burden". I'm having trouble finding what that would be for a typical household plug ammeter without avoiding all the "power meters are great" spam sites. I assume it is very small.

        I'm using Shelly EM at the entry (for the entire phase), relays with PM at some sockets with interesting devices and shelly plugs at some sockets that need to be easily serviceable (think behind kitchen cabinets, for the built-ins). The consumption of each of them is below 1W.

        Nobody is missing 50w any more because that goes on their BOM as a bigger power brick. I can see this stuff where someone missed an incandescent or hasn't replaced a device in 10 years but really stuff has moved on and cost optimisation is relentless.

        i had access to industrial power meters designed to 120A 400V so that is what i used, but the typical household here would not go over 4-7 kw and you can buy cheap digital meters from AliExpress with display and so on they can measure up to 4kw i believe.

      Yes it's huge, but not out of the question for some people who go all in on some things in their house. For example, in my place right now: - Unifi rack (some switches, cameras, other PoE stuff) - 335W - Servers (home automation, NAS, etc) - 426W That's all the time, Unifi actually goes up at night when the IR LEDs come on in the cameras.

        That's still insane. I have a Hue bridge and server at home that together draw less than 50W. Network equipment is also in the range of max 10W per device.

        That's not "idle" use... somebody wasted good money on those labour-saving devices. And they'll write a blog post about it too once they get around to fixing them! (I write this lovingly yet seriously as absolutely a victim of this exact same dynamic, sitting next to a pile of expensive fans I'm going to use to reduce the noise from my rack... any day now...).

    Which modern PC draws 30W when off? When mine is off, the electricity calculator states 0W (the draw is less than it can register). Even for sleep mode that would be huge. 30W is about the normal modern PC idle (on, but not doing anything) consumption, not any sleep / standby / off state consumption.

      The specific case I'm thinking of was an Advantech AIMB-274 with a Mini-Box PSU (I don't remember which one). I was evaluating this setup for inclusion in a battery powered mobile robot; in particular we needed to decide whether the computer could be hooked up to the battery full time or if there needed to be a relay in between them in order to preserve the battery when the robot was "off". The answer turned out to be that we very much needed to disconnect the computer. Admittedly this is not a consumer PC or a "modern" gold/bronze-designated power supply, but I still thought it was pretty significant.

      My ASRock B450 Pro4 draws about 3W from the wall if WOL is enabled, which in ASRock's firmware seems to keep all PCI devices (and attached USB devices) powered. 30W seems impossible though, anything not specifically designed to be fanless will almost certainly need to turn on the fan at that power usage (and even fanless might have difficulty dissipating a constant 30W).
      - marcosdumay 4y ago
        Monitors can dissipate a huge amount of power without a fan. The OP blames mostly them, and their stand-by power consumption usually isn't even available to a buyer.
        mikepurvis 4y ago
        Surely the display panel itself is switched off when on standby, though? Is this a case of not including a separate standby power supply circuit, so that it's the "main" one inside there running at a fraction of its capacity, where it is least efficient?

Sure, it'll be a while before I had something cleaned up nicely, however I've added some screenshots to my original post.

I'm wondering too. I actually tested almost all devices at home and the idle power consumption actually quite different from my previous perception. The following are a few I tested: 1. Microwave Oven. ~3W. 2. DECT phone base. ~2W. Extension unit. ~1W. 3. IP phone. ~1W. 4. Cable Modem. ~10W. 5. Routers. ~3W to 20W. 6. Switches. ~1W to 30W. 7. NAS(4Bay). ~40W. 8. Raspberry Pi 3B. ~3W. 9. Chargers/Power adapters. ~0W to3W. 10. WIFI Smart Plugs. ~1W when switch off. ~1.5W when turned out, both no load at all. 11. Set top box. ~15W, on or off. 12. PCs/Laptops. ~3W off, ~5W to 15W on. To me the DECT phone, Set top box, cable modem consumes much more than I thought. Routers/Switches are more or less align with what I thought. What surprised me was that chargers/power adapters from decent brands were doing much better than I expected. Most chargers/power adapters I have consumes ~0.1W when idle, some event shown as 0w. Except one dodgy one came with a cheap toy PC behaves pretty weirdly: peaks at around 10w when just plugged in then gradually reduced to ~1.5w. Might be because it is a traditional power supplier with a transformer in it. So the standby power consumption of my household should be just below 100W and I don't see how I can get it close to 500W.

how did you get 500w of idle use. that does not make sense. could you please post your table. i have my pc all the time on and some other things and not even close to that.
