Despite not being able to reach C10 in Powertop on Unraid, I'm idling at between 9w and 15w on the AC side with the HDD spun down. Best I can get is C8. CPU: Intel Core i3-12100 MB: ASUS Pro H610T D4-CSM Ram: Crucial 32GB DDR4-3200 SODIMM NVMe: Lexar NM790 M.2 2280 PCIe Gen 4x4 NVMe SSD 2TB HDD: WD Ultrastar HC550 16TB 3.5" Enterprise PSU: Toshiba 19v 120w Laptop Brick Tried running without any drives and no better, still only C8. All components report being ASPM enabled when I run : lspci -vv | awk '/ASPM/{print $0}' RS= | grep --color -P '(^[a-z0-9:.]+|ASPM )' So I'm now stumped with how to get to C10

I have this same motherboard and I tested it using the molex connector from a 500w ATX PSU. The 4 pin one that would normally plug into a video card, two of the pins are the exact match for the ASUS pro board. The 12v rail is rated at 200w so I figured I would test based on Bagican advising that it worked at 12v. I can confirm that it posted so yes you should be able to use a standard ATX PSU. Would just need to modify the connector to remove two of the pins as it overlaps with one of the fan connectors.

@bagican Are you able to advise of the BIOS changes you made to reach C10. Only reaching C3 atm.

I caved in and went the Bagican way: CPU: Intel Core i3-12100 3.6 GHz Quad-Core Processor MB: ASUS Pro H610T D4-CSM Ram: 1x Crucial 32GB DDR4-3200 SODIMM NVMe: Lexar NM790 M.2 2280 PCIe Gen 4x4 NVMe SSD 2TB HDD: WD Ultrastar HC550 16TB 3.5" Enterprise HDD: WD Green 2Tb 3.5" Hopefully should have all the parts this weekend and can fire up my first unraid server. Plan is to operate as a NAS with: Sonarr Sabnzb Plex FTP server to receive photos from my security cameras Storing TV Movies Music Photos Whilst I store photos on my current NAS they are synced up to the cloud in multiple locations so parity is not required.

Hey Bagician, On your recommendation I've ordered the same motherboard, config will be: CPU: Intel Core i3-12100 3.6 GHz Quad-Core Processor MB: ASUS Pro H610T D4-CSM Ram: Crucial 32GB DDR4-3200 SODIMM NVMe: Lexar NM790 M.2 2280 PCIe Gen 4x4 NVMe SSD 2TB HDD: WD Ultrastar HC550 16TB 3.5" Enterprise HDD: WD Green 2Tb 3.5" Hopefully I can get similar power results to you.

@bagican Great thread. I've found a couple of boards available in Australia that might be what I'm looking for but it not then I'll order one like yours from the US. ASRock B660M-PRO-RS/AX - https://forum.level1techs.com/t/in-the-pursuit-of-low-power-consumption-nas-with-alder-lake-12th-gen/188407/6 ASUS Prime H770-Plus D4 - https://mattgadient.com/7-watts-idle-on-intel-12th-13th-gen-the-foundation-for-building-a-low-power-server-nas/ I'll need to read these two articles more carefully and deep dive into their specs but hopefully one of them will be suitable.

Yes, your post is exactly my issue. That board is not available in Australia, I would have to buy it from the US and have it shipped to Australia. I'm not adverse to this and will do so but I'd like to try and locate something local first. I don't have a power number in mind, I'd just like to not accidently pick a motherboard that lacks the suitable controls and end up using more power then I need to. Max HDD = 2, haven't worked out if I'll add an SSD yet. The main limitation will be the picoPSU but I may have to replace it anyway.

I need some help, I've been paralyzed for weeks trying to decide on hardware for a low power media server. I first decided on a Synology DS224+ but then I came across unraid, 12th gen intel CPU's, quicksync and the ability to get similar lower power results with cheaper more powerful hardware. Usage will be: Sonarr Sabnzb Plex or Jellyfin or Emby FTP server I've decided on the Intel i3-12100 as the CPU but I can't match a suitable motherboard that along with powertop will yield low power results. I normally do my own research rather than ask for help but I've come undone this time as when I find a post about peoples experience with a low power build the motherboard listed is unavailable in Australia or three times the price making the Synology more attractive. My basic hardware CPU - Intel Core i3-12100 RAM - 2 x Crucial CT8G4DFRA32A 8GB (Would a single stick of 16Gb be better?) HDD - WD Ultrastar HC550 16TB SDD - ? PSU - picoPSU pico-PSU-120WI-25V I'm hoping that the pico-PSU will be enough as it's recycled from a HTPC build but I can replace it if not. Can anyone help me choose a motherboard that should allow good adjustment using powertop? Or at least help we work out what I need to look out for?
