Why I chose an N100 over a Raspberry PI5

  • I can only tell how to change PL1 of Asus Prime N100 via CLI:


    Code
    set to 12W
    * apt install powercap-utils
    * /bin/powercap-set -p intel-rapl --zone=0 --constraint=0 --c-power-limit=12000000 --c-time-window=55967744
    * /bin/powercap-set -p intel-rapl --zone=0 --constraint=1 --c-time-window=4880
    
    Check current settings
    * /bin/powercap-info -p intel-rapl


    This will no survive reboot. So if you want that to be permament add it to a boot script

  • Unfortunately, I don't really manage with the settings in this Asrock bios for n100dc itx.

    If anyone is willing to share their settings with me, I would be grateful.

    Especially how to adjust pl1 and pl2.

    I have one nvme ssd, one sata3 ssd, one 3.5" HDD, one 12cm fan connected to the mbo.

    I use 19V 4.74A 90W power supply.

  • It's just a 19V laptop power supply. The ASRock N100DC-ITX Intel Q-Core N100 has no ATX power connector, only a 19V DC jack for power. The board has a power connector for 2 SATA HDDs/SSDs. Without the HDDs it draws 8.4W in idle. With the 2 HDDs it draws 15.5W in idle. When writing to the HDDs it's 25W.


    What do you do about the hole in the case intended for the PSU in this case? I've never seen a case include a cover in case you're using a pico PSU or built-in PSU like the Asrock has.

    Or leave it open. the case will breathe better.

    Mine doesn't have a hole.

    The PSU would be mounted on the front.

    IT has a power port with an extension cord.

  • I read what you linked and I have to admit that I didn't really understand it.

    Can you explain to me, as in the instructions for idiots, how to set it in the bios to get 6W?

    I didn't do it myself. I like the 10W long duration power limit.

    From what I understand you would need to set the value for the long duration power limit to 6.000.

  • Did You make any special settings in BIOS regarding power consumption?

    I ordered this mobo to replace my AsRock J5040, after reading this topic I expected to have similar or lower power consumption and much powerful CPU and iGPU

    But after setting everything and launch, I'm really disappointed - power consumption is ~19-20W in idle while it was 12-13W on J5040 (all disk in standby).

    I'm using PicoPSU 160W

  • I'm currently building a second NAS based on an Asrock N100DC mbo.

    I found an old power supply that, according to the label, meets the required specifications, but I would like to measure it just in case if it's correct, so I'm wondering what values it should have?

    I'd also need a recommendation for a quality power supply that is available on amazon.de or aliexpress

    A Leicke power supply was purchased for the first NAS, but given the many negative experiences I'd like something of a higher quality just in case. Unfortunately, I can't find the ones that Asrock recommends.

    Maybe I worry too much, but that's me. ;)

    No. I didn't change anything.

    But after setting everything and launch, I'm really disappointed - power consumption is ~19-20W in idle while it was 12-13W on J5040 (all disk in standby).

    I entered that data into a comparison. https://technical.city/es/cpu/…r-J5040-vs-Processor-N100


    Judging by the numbers, the two systems are quite similar. Personally, I wouldn't have changed the system unless there were reasons other than performance or power consumption.


    As you can see from the tests I ran, most of that 20W consumption you have is due to other hardware components other than the motherboard. So I would look at the hard drive configurations and so on; maybe you need to configure something the same as before.

  • Thank You for Your answer.

    Personally I checked comparision on the other bechmark, and the difference was quiet big:


    The question is - which bechmark is more valuable in reality.


    The reason why I changed it was:

    - Want to increase performance - I saw that some apps like Nextcloud was too heavy for J5040 (it worked but no quick as expected)

    - Having better iGPU with QVS supporting more video codecs (and this is fine - transcoding in jellyfin is much better)

    - Expected the power consumption will drop down


    If I would not read so many positive info about this board, I would not buy it - J5040 met 98% of my needs, had 4SATA by default + 2 thanks to M2 Wifi slot, was rock stable and as I see now - really good optimised in power consumption.


    That's why I;m so dissapointed and now I also thought the replace was not good idea.


    I tried switch off everything in bios but consumption is on the same level (17-18W in idle) - powertop -autotune helped a bit, because before it was a 21W


    Have no idea what to do more...

    The question is - which bechmark is more valuable in reality.

    Regarding hardware test results, benchmarks, and other figures, I would try to read them with some caution. There are many different benchmarks, and each one may or may not be important to you depending on your end use of this hardware.

    - Want to increase performance - I saw that some apps like Nextcloud was too heavy for J5040 (it worked but no quick as expected)

    Yes, you will obviously have better performance. The question is whether the difference justifies the change. I'm not a Nextcloud expert, but I suspect the determining factor is the write and read speed of the Nextcloud database. And this doesn't depend on the CPU, but rather on the speed of that database's support. I use Nextcloud with an NVME drive (speed restricted to 1GB/s because it's installed on a PCIe adapter) for Docker, and it works fine with the N100.

    - Having better iGPU with QVS supporting more video codecs (and this is fine - transcoding in jellyfin is much better)

    That's a good reason to make the change. If you need more modern codecs, this is the only way to get them.

    - Expected the power consumption will drop down

    Some performance should decrease, but I think if we're talking about small differences (both systems are low-power), you shouldn't notice a big difference. Most of the power consumption is not related to the motherboard but to the rest of the hardware (hard drives, power supply, etc.)


    ___________________________________________________


    In general, I think there's a big power barrier between using a low-power system and a conventional desktop system. If you're comparing two low-power systems like the J5040 and the N100 (or a Raspberry Pi 5 or similar), the power differences will be minimal. That's when the other features come into play.
