Hi All,
I have BKHD BK-NAS-N5105 (
BKHD N5105 1338-NAS).
At the moment I am testing this board based on Windows 11, but eventually I will put ProxMox on it. I am disappointed with the energy consumption. Like others in this group, I am far from a dozen or so watts.
3) power consumption is shocking 25W idle, 32W when nework+HDD are working (in xpenology CPU load is 6%). it is more then stadrard desctop consume with celeron CPU.
My basic configuration:
- one NVME disk (Adata)
- 32GB DDR4 3200 (Crucial)
- PCIE WiFi card (without a WiFi card, the consumption drops by 1W).
- 120mm fan (instead of the original one because it was terribly loud)
- 250W SFX 80+ power supply
- default settings in BIOS (factory reset after updating the BIOS to the version of 2023-08-04)
Here are my observations:
- power off (standby) - 4W!!! (my normal PC can take max 2-3W)
- boot (under bios and under system load) 25W-27W
- stress 33W
- normal work (browser, copy files) 25W
- idle 21W
- sleep 4W
I don't want to turn off the network cards, but I know that turning one off gives a gain of about 0.5W.
I checked whether it was the power supply's fault, but on another SFX450 Corsair the results were the same. My normal PC with I7-8700K in idle can go down to 24W!
During my tests, I had a situation twice when the system consumed 12W in idle mode and 15-17W during operation, but I don't know if it was then that the meter had a problem or if it was due to the fact that I turned on the board that had previously been in a cold room without electricity for a long time. . After hundreds of attempts, I was unable to repeat this situation again.
Please help me understand what this is about? Is this just the way this model is and there's nothing you can do about it? Are there any settings in the BIOS to reduce the consumption below 20W?
Can you share your observations because I don't know whether to search hundreds of pages on forums or accept this state of affairs.
I read on the Unraid forum that someone modified the bios, but the link to it no longer works. There are different models of this board (green, black), do all of them have it or only this model (BK-NAS-N5105) has it? I will be appreciate if someone who has this motherboard and has low power consumption could share with BIOS details.
