Did you saw this? https://github.com/badger707/m920q-pcie-bifurcation/issues/1 He claims to successfully enabling X4X4 by replacing the resistors without any additional BIOS mods. As far as I know its not possible to modify the BIOS of current gens as they are protected by certificates...

I missed to measure a fully disconnected port, but between 10G and 100M are 2 watts (RJ45): https://forums.unraid.net/topic/108966-strom-sparen-mit-powertop-stromverbrauch-von-unraid-verbessern/page/12/#comment-1080683 Not sure how huge the effect would be with active DAC cables.

The best option is still to buy a dual or quad 10G card and avoiding a 10G switch. Instead connect the server directly with the clients. By that the port itself powers completely down when the client is switched off. In addition you save 10W or even more for the switch. Of course this works only...

Again a real world example. The 980 pro consumes more power in idle if PCIe 4.0 is used: https://www.anandtech.com/show/16087/the-samsung-980-pro-pcie-4-ssd-review/8 And note: Anandtech measures the nvme alone. There is even an PCIe 4.0 overhead from the cpu/chipset which is not part of the...

But why aren't there any as or more efficient setups? Using PCIe 4.0 components on a X570 setup raises the power consumption and doesn't lower it. And this isn't something which becomes even by stopping all other components earlier as your file transfer of a PCIe 4.0 NVMe has done it's job...

I hope somebody will release an energy-efficient W680/W685 ITX Workstation board without IPMI. The last efficient was the Gigabyte C246N-WU2 and it was sold out every 2-3 weeks. There was no W480 or W580 or C256 ITX board without IPMI. By the way, will PCIe 5.0 raise power consumption? What if...

What about the Intel X710-DA2? Dual Power Consumption is between 3.3 and 5.1 W: https://www.intel.com/content/dam/www/public/us/en/documents/product-briefs/ethernet-x710-brief.pdf The X520-DA1 Single Port is much worse, but as its really cheap its maybe an option with DA Twinax...

At first: Do not buy the Asrock C246 WSI. It has a high energy consumption, high reving fan, no full M.2 slot, crazy ATX connections and needs an expensive Oculink cable, etc. The Gigabyte C246N-WU2 is much better in any aspect and consumes much less energy. And regarding the ATX 4 and 8-Pin...

Now, they are sure ^^ So if you want to use an ASRock product you need to buy Supermicro accessory. :D

@Evan So its more a typo and he meant 24.1W? I though 14W would be realistic after the C2750 had a similar result (looks like 16-17W in the chart): https://www.servethehome.com/supermicro-a1sai-2750f-review/ Sadly these Atom boards do not contain a jumper to disable the IPMI chip. I'm sure this...

Hi, I asked it in the review comments, but maybe I receive here an answer. You tested 14.1W in idle. I bought it and my setup (1 RAM module, no ethernet connection, one SATA SSD) does not go under 20.2W. I'm using a +/-1W power meter and if I power off I get a similar result as yours (5.2W)...
