    Due to the current crisis I've bought a cheap device to measure power usage at the outlet.
    Code:

    idle compiling off(standby)
    iMac G5 72.4W 97W 3.3W 2.5GB RAM default screen brightness
    Peg2 G4 54.5W 57.2W 1.5W 1GB, Radeon 9250, some old HDD, passive PSU
    22" LG 35W ---- 0.5W 1680x1050


    Plan to add more PPC and non PPC-HW later, but the shocking result atm is that it makes more sense to run the iMacG5 standalone than running a Pegasos_G4 and an ancient TFT with similar specs.

    Good idea! Could do some measurement on my G5 11,2 and G4 3,6 too.

    Interesting. In light of the old discussion from some years back, do you have access to any PowerMac G5 and can measure standby there?

    HW that I plan to add in the coming weeks:

    PowerMacG4 1.8GHz (with and without the 22" ADC + the ADC on it's own PSU)
    PowerMacG5 2x2.3 (AGP)
    EFIKA
    QuadCore "Atom" PC
    HexCore 2010 MacPro
    Base model MacStudio
    Maybe some 68k HW, 2010 iMac and MacMini

    Various (LCD) monitors ranging from 1998 18" to 2020 32".

    From my own mesurement interessting behaviour G5/2,3GHz:

    Powerconsumption (with monitor, audio-subsystem and tiny-WLAN-hub is in OpenFirmware near 290W, at MOS about 260W and in OSX 196W! (ideling)

    OSX has a good powermanagement, that's for sure, but OF does'nt seem to have anything (diff=100W!!!)......thats a surprise to me.

    Interesting. My PCIe 2.3 takes about 190W when idling on MorphOS. That's with R1950, an Nvidia and a SSD drive and Realtek eth. Optical drive removed.

    Measured with Emporia Energy Vue.

    Quick test with the 2x2.3GHz G5 running a 3.10 beta (so any improvements to power management in the past 5.5 years does not apply).

    Idle: 211W compile: 215W standbye: 2.3W

    Needless to say this won't return to daily usage anytime soon....

    Thanks. This is the exact middle of the 0.9...3.7 W range mentioned back then (as opposed to the 30+ W some claimed to have measured).

    @Jacad: I think I'm not far away to yours: keep in mind, that monitor and WLAN-hub consumes about 60-70W too. Will check PMac allone tomorrow.
    Surprising for me is, that OF seems to have no real or efficient powermanagement (compared to OSX or even MorphOS) - did'nt expect that!

    Could be, that I have to test another G5 with different OF, because this one goes (in OF console) after 3 minutes allway to full power blowing (thermal calibratioon is OK).

    Measuringsystem is calibrated UNITEC EIM-812 performance measuring device (CATII) - should be exact enough.

    Powermac7,3 (G5 2x1,8 GHz) with ADC 17" Studio Display and MorphOS 3.17, with dnetc running: 177 W.

    No comparison to OSX, since this machine is MorphOS-only.

    Measured the Efika years ago: https://via.bckrs.de/MorphOS/bench_en.html (sd card should lower the uptake quite a bit)

    Also on that site, measurements for the mac mini and pegasos1.
    I can confirm your conclusions from the total energy uptake POV as written in this thread already https://morph.zone/modules/newbb_plus/viewtopic.php?forum=11&topic_id=12759&viewmode=flat&sortorder=0&start=25

    There is no powermanagment in OF so it is normal to go into jet-mode after a while.

    The cooling on these is good enough to have the CPU(s) at full blast without damage for forever in contrast with current (x86) CPU that would easily kill themselves running full tilt on their stock coolers.

    What's notably off though is the standby consumption of the iMac G5, where you measured 11 W and Kronos only 3.3 W.

    No, depends on Firmware.

    PM G5 (OF V4):

    PM 2,3 GHz : 5.1.87f allways silent
    PM 2,3 GHz : 5.2.4f1 blowing like a jet
    PM 1,8 GHz : 5.1.5f0 allways silent
    PM 2,0 GHz : 5.1.8f7 blowing like a jet

    Seems that OF Versions 5.18f7 and above dont manage that as good as older FW-revisions.
    It's also very interessting that this 2 blowing G5 have that backside blower-problem under MorphOS too, which I discribed in another thread. Northbridge becomes much more hot, than the other two G5. Astonishingly under OSX it does'nt occour.

    The device I've bought is really cheap so I wouldn't trust it to 100% precise.

    Difference can be up to variations in the PSU (and they decay of the notorious caps) or maybe some "wake on LAN" feature that may exist and be activated.

    FYI just did my old 27" (2560x1440) Dell and it claims 0.0W for standby and 37.3W when used. Given that is almost 1.5 times the surface of the 22" with just 2W more I am starting to suspect that the 22" is just bad.

    Tested now a G2 2.0GHz/ Dual_Cpu, Radeon 9600P, HD 1x2TB, 1xDVDRW, 1x IDE2CF, 2GB RAM
    No other el. consumers

    Off: 20W
    OF: 250W (allways)
    MOS: 220W - 230W (Idle - Wayfarer loading/Playing Youtube)

    That's a remarkable (and daunting) difference to Kronos' 2.3 W.

    Just take note that some power measuring devices get completely confused if there's a bad power factor. PSUs tend to have pretty bad PF.

    With the release of 3.18 (or the 1st 3.19beta to be more precise) I decided to check up on some mothballed systems:

    PMac G4 QuickSilver 1.8GHz Radeon9000:
    idle 55W compiling 83W standby 10W
    idle with 15" ADC 75W
    -> far to high standby to be connected to mains 24/7, despite the slower CPU and smaller screen it pretty close to the iMac and it still lacks the USB2,SBLive! and Voodoo3 I had in there

    I suspect the stand by values may be a bit off due to measurement errors (blind currents , Phase Shifts). Would need some in depth Evaluation…
    But eventually I think it‘s a good idea to keep these machines behind a mechanically switchable power outlet like this https://www.pollin.de/images/1200x1200x90/I451056.1-goobay-Schutzkontakt-Zwischensteckdose-mit-Schalter-16-A-weiss.jpg

    I use a powerbar with switch since 2nd screen is of similar vintage (2008 I'd guess) and there is no point in having it on when the iMac (or PMac and Pegasos2 before) is off.

    Did anyone provide numbers for the AGP vs. PCIe PMacG5 off/standby power ? At least I was under the impression that the AGP models were drawing way more power in standby than the later PCIe ones.
    If it would really be about 20W in standby for some models, it definitely would make a considerable ~170kWH over a year just for staying in standby ....

    Please, can you tell me what exact CPU do you use, and what Core Voltage?
    I have PMac G4 MDD now and two pairs of spare CPUs: MC7457 RX1267LC and SC7457 RX1267LC and I have in plan to exchange CPUs and overclock it.

    Thank you for any experince.


    P.S. and if this is power consumption thread, with 1600 MHz original MDD CPU XC7455B RX1400PF has power consumption cca 63 W and my spare 7457 only 33 W. So I will save some Watts ;-)
