I'm trying this build and i'm still looking for the PSU.

Asus says 180W, here are used 150W. PSU Calculator says 180W but i think its still way to overpowered.

Is 130W enough, or can we go even lower? (To improve the efficieny of the PSU)

 

Any suggestions?

I'm using 120w without issues. 

 

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

Is it possible with the ASUS Pro H610T D4-CSM to set the PL1=10W and PL2=25W? Then it should be actually possible to cool an i3 without fan.

What's you running on the system? When you load CPU 100% and HC550 is spinning what do you get on DC side W?

What do you get on DC side when system just running(cpu running regular stuff docker whatsoever) and HC550 is spinnig?

Hi Guys!

 

am i right in assuming that if i want to switch to 12400 then the 12v 120w adapter will not be enough?

Should I use a 19.5V 9.23A 180W charger?

with that board (Asus Pro H610T D4-CSM) the CPU TDP will be limited to 65W max. This board has limit 65W for CPU.

120W adapter will be enough (if you don't plan to run in 100% CPU load full-time)

Thank you.

I installed a 60W PSU and it works fine till CPU to 50%, sometimes even higher.

 

My system is idling most of the time at 2-3%, cause of the huge CPU power (in comparison to my first server).

Maybe this helps others in this situation.

@bagican did you tried also on the pci Port?

 

I found an comment on mattgadient regarding this topic.

 

Found here

 

Ich weiß nicht, ob es von Interesse ist.

Ich war in der Lage, die asmedia 1166 auf dem pcie x16-Steckplatz zum Laufen zu bringen und den m2-Steckplatz mit der CPU zu verbinden und c8 zu erreichen.

 

Ich musste das Asus-Bios modifizieren, um Zugang zu den Root-Port-Einstellungen zu bekommen. Deaktivierte Multi-VC auf Root-Port 1 und kann nun den x16-Steckplatz verwenden und ich erreiche den c8-CPU-Paketstatus. Ich erreiche c8, wenn ich den m2-Steckplatz verwende, der gleichzeitig mit der CPU verbunden ist.

 

Vereinfachte Schritte:

BIOS von der Hauptplatine deinstallieren

Dump BIOS mit einem ch341 3.3v Programmer

BIOS mit OpenSource UEFI-Editor und "unhidden" Root Port Einstellungen modifiziert.

BIOS geflasht

wieder zurückgelötet.

 

Mein Motherboard ist ein ASUS PRIME B760M-A D4, aber es sollte das gleiche auf Prime H770-Plus D4 sein.

 

Ich muss dem Intel-Support für den Vorschlag danken, Multi-VC zu deaktivieren, das hätte ich selbst nicht herausgefunden.

 

Question would be: is this working or can we use PCI express asm1166? 

Iam very interested in this bom here for nas it seems very good with 4x SATA Drives

Hi @de-sascha ... as I promised you (on hardwareluxx.de) I tested it today (few minutes ago) and this mainboard doesn't play well with the ASM1166 m.2 to 6x SATA adapter.

 

TL;DR:

without ASM1166:

idle: 2-3W ⚡️✅

- C10 (~91%)

 

with ASM1166:

idle: 14.1 - 14.5W ⚡️⚡️⚡️⚡️⚡️

- with ASPM L1 on all devices

- no errors in dmesg

- C2 max (~98%)

 

See more stuff, screenshots, results, ...:

Debian 12, kernel 6.1.0-18

 

idle: 2-3 W (without ASM1166)

 

...

 

-----------------------------------------------------------------------------------------

 

now, with ASM1166

 

- powertop: only C2

 

I have tried several combinations of L1 or "L0s L1" for ASPM:

 

 - idle: 14.7 - 14.8 W

 

 - idle: 14.2 - 14.4 W

 

 

 

- here you can see my powertop html report: https://jsbin.com/rolehanuqi/edit?output

and my whole dmesg log: https://pastebin.com/18FZnAAB (after restart, without ASPM applied) and after powertop and ASPM enabled: https://pastebin.com/aTyQnvAZ 

 

But be aware that I tested my ASM1166 adapter in Odroid H3 and power consumption increased only +1 W (as you can see here)

 

❗️TODO:

- Also, I forgot to upgrade BIOS, so maybe I will update this post tomorrow with newest bios.

- ❗️It would be great to test another SATA SSD, because I've used old 128GB Crucial M4 SATA SSD (11+ years old).

 

______________________________________________________________________________________________

UPDATE:

️ - Updated BIOS to newest (Version 3202, 2024/03/07)

 - Changed old 128GB SSD to new Samsung 870 QVO 2TB

detail on idle with ASM1166:

 

 

 

 

 

Room temperature: 23°C

CPU temperature (passive/fanless cooling with special aluminium case):

 - idle without ASM1166 (package C-state in C10) : 29~30°C

 - idle with ASM1166 (package C-state in C2): 36-37°C

 

 

 

Is ASM1166 still a problem with this mainboard? Or was someone able to manage to reach lower C-states with ASM116?

// note: I have tried only M.2 to 6xSATA adapter (ASM1166) since this board has no PCI interface / slot.

Power supply:

- currently I'm using 12V 150W from AKASA (mentioned at the beginning with other hardware)

- I would like to try and compare with some other efficient power supplies. My candidates are:

  - MeanWell LSP-160-12 https://www.tme.eu/en/details/lsp-160-12t/built-in-power-supplies/mean-well/ (efficiency 92.5%)

  - or MeanWell UHP-200-12 seems promising too, efficiency 93% https://www.tme.eu/en/details/uhp-200-12/built-in-power-supplies/mean-well/ ... I found this one as most efficient (93%) but I know it depends on the load... (so it may not be as efficient in small loads <10% of PSU load capacity)

 

Power backup:

- later I plan to add DIN mountable 12V redundant power unit from MeanWell and 12V UPS battery backup - also from MeanWell

 

 

Have you ever tried using the MeanWell LSP-160-12 or UHP-200-12? How did you physically connect it to the board? Did you use the same 4-pin to 5.5mm adapter, or did you connect it directly to the motherboard’s ATX19 connector? What power consumption levels did you observe?

Also, when using a MeanWell power unit, assuming you place it inside the case, would you connect it using the ATX19 2 pin connector instead of using a 5.5mm barrel adapter?

Edited January 12, 20251 yr by alex_s

Unfortunately I have not tried MeanWell yet. I'm fine with Akasa "brick" power supply.

What type of adapter do you need to use a laptop? PowerBrick with a motherboard, such as Asus or Asrock?  Sounds like a great idea since I have like a Dell 19.5V 180 W PowerBrick sitting around.

We have successor of this awesome mainboard (Asus H610T D4-CSM).

I doubt it will have such low idle power consumption (less than 5W) because Arrow Lake CPUs are not so efficient in idle

How did you get past the C3 states? While using the same motherboard(Asus-h610t), my progress is being blocked by a connected ethernet cable, preventing me from  going beyond the C3 states.

@hCoreX what is your full HW configuration - CPU, RAM, SSD, ... ? And SW - OS ?

I am currently using i3-13100 with 32gb or ram and samsugn pro 980 2tb on a headless arch 6.12.39-1-lts

I found a solution, turned out there was a file in Linux sysfs filesystem where ASPM was disabled. Enabling the l1_aspm file let me reach C10

states, but it did bring down download speed notably. Although enabling both l1_1_aspm l1_2_aspm and clkpm wasn't necessary, they did come with

a higher performance cost. Interestingly, upload speed stayed the same at 45 Mbit/s despite any changes made.

PS: Just after writing this message, I found out that the solution to enable ASPM had already been shared, but I must've missed it.

I doubt it will have such low idle power consumption (less than 5W) because Arrow Lake CPUs are not so efficient in idle

- No realtek 2.5G

- limited sata

- arrow lake too expensive for such application

- PCIe 5 will eat power if used.

+ DDR5 low power

6th-12th gen is a better choice.

Arrow lake is very efficient at idle e.g. 2.1w for 265T (5.8w with monitor attached):

https://www.energystar.gov/productfinder/product/certified-computers/details/3892093

The problem is neither Intel nor any OEM's care at all about LGA arrow lake.

another similar thin mini-ITX from ASRock: https://www.fanlesstech.com/2025/08/asrocks-thin-mini-itx-trio.html

specs: https://www.asrock.com/MB/Intel/H810TM-ITX/index.asp

• Storage:

  • 1 x M.2 2280 PCIe Gen5x4 SSD

  • 1 x M.2 2280 PCIe Gen4x4 SSD

  • 2 x SATA3 6.0Gb/s ports

• RAM: • CSO-DIMM version: 2 x DDR5-6400MHz slots, up to 128GB

  • SO-DIMM version: 2 x DDR5-5600MHz slots, up to 128GB

• LAN: 1 x 2.5 Gigabit LAN (Intel^® I226V)

• power: 19V DC connector

I'm not sure about reaching C10 with ASRock because if I'm remember correctly, ASRock is known that it has "hardcoded" limit to C3 or C6 (or so). But there are guides how to enable "hidden BIOS menus" and how to achieve C8/C10. Simply: ASRock = energy inefficiency

Edited August 19, 2025Aug 19 by bagican

I am interested in building a particularly energy-efficient NAS. I am not yet sure whether to use Proxmox v9 and Unraid in a VM or Unraid bare metal.

Currently, my Unraid is connected to an Odroid H2+ with 1x NVME cache and 2x 22 TB HDDs. With sleeping disks and idle, it consumes about 6 W.

All other boards I have tried are at least twice as high (Frankenstein M920x/M90n-1, i5-12xxx, old xeon...).

The Odroid H4ultra would be an option with 4x SATA, but it's too expensive for me without PCIe (I'm more interested in the principle of low power consumption).

Now I'm planning:

Asus Prime H810M-A-CSM

Intel Core Ultra 5-225

2x16GB RAM

Then I would have

4x SATA

4x NVMe

Unfortunately, only 1 Gbit onboard NIC

Would an idle power consumption of less than 8W be expected in this setup?

Ok I think I am actually cursed. 4th server and still havent seen anything above C3.

This latest one has:

Asus Pro H610T D4-CSM motherboard

Intel i3 12100 cpu

Kingston KC3000 1TB nvme

SK Hynix 2x16GB DDR4 SO-DIMM ram

19v 6.32a (120W) power brick

2x Noctua 40mm fans

Thermalright axp90-x47 full copper cpu fan

With just proxmox running, idles at 13W measured from my Tuya Zigbee smart plug.

Tunables are all good and WakeUp are all disabled.

ASPM are all enabled.

CPU governor set to powersave

@silicon4079 Have you tried in BIOS not to change [HD Audio, Serial Port] to Disabled? I didn't disable them.

also I would like to try change SSD, some SSDs have somehow bad power management.

I think Kingston KC3000 is not good choice for power efficient buid.

I had HD audio and serial port enabled at the start. Dunno if they actually made a difference alone as i also adjusted other things but probably not.

And yeah I do suspect the KC3000 is the reason. I had another KC3000 (2tb) (two of them) in my unraid server and when i swapped it to a samsung 990 pro (2tb) (two of them), my idle went from 27w to 20w but still in C3 with both. So if thats the same case here.. swapping to a samsung should save me at least 3.5w if not 7w if its the same. But with how expensive nvmes are getting now its definitely not worth it to spend 200+ usd for a 2tb drive for a potential 7w lower idle imo.

https://forums.unraid.net/topic/98070-reduce-power-consumption-with-powertop/page/43/#comment-1540208

KC3000 is definitely high on that list.
