I “made” a power supply for the DC for CWWK n305. This will step down from 12v to sata power and molex (for nas backplane)
12gen N-series Nas motherboard (topton, cwwk, ... )

I orderd the N305 Version yersterday and have some questions open in my mind:
Is there any Recommendation for a single DDR5 SO DIMM?
And is there any experience if using both NVME Slots will prevent higher Cstates?

You can forget about higher Cstates if a JMB585 sata expansion card is enabled. I have not tried to use both M.2 slots with NVMe SSD.
I have done some investigation about C states...
I purchased an ASM1166 sata expansion card, updated the firmware and plugged it into the second m.2 slot (I have a Samsung NVMe SSD in the first m.2 slot). Unfortunately, when ASPM is enabled on the ASM1166 controller, the UNRAID system does not see any HDDs connected, but C8 states are reached. When I disable ASPM in the BIOS settings for the pcie port that the asm1166 controller is plugged into, UNRAID sees the connected HDDs, but only C3 states are reached.
I thought that ASM1166 controller with correct firmware supports ASPM and therefore higher Cstates.
I might try to plug it into the other m.2 slot...
Any ideas?

I wanted to unse a PCIe x1 Card with ASM1164 and disable JMB585.
That should enable lower cstates. Hopefully disks will appear then. Bad is That ASM1166 is not available for PCIe 1. I have found none :/
I found the issue: if ASMxxx is connected to CPU Lanes you will not reach good cstates. If it is connected to the chipset you will. But this Board does not have any lanes from a chipset.
Only way would be to use both m2 slots and the native sata slot to get most energy savings.

The second m.2 slot doesn't really support ASPM in my opinion.
I swapped the nvme ssd with a sata controller. The nvme ssd was unavailable then but the HDDs were recognized by the system.
What about the pcie x1 slot? Does it support ASPM?
My naive goal was to disable the JMB585 Sata controller and connect the ASM1166 to the other m.2 slot or to the pcie x1 slot

The second m.2 slot shares the same lanes as the PCIE x1 slot, so you can just use one of them.

some pretty thorough N100 disk benchmarking on here (and compared vs N5150 version):
Thought this was quite interesting to see.

So I have finally managed to reach c8 states with an asm1166. The trick is to plug it into pcie x1 slot instead of second m.2. The system idles at 15 to 16 watts.
What picture of my setup? You have the same board
The second m.2 nvme slot does not support ASPM, which is needed to achieve higher Cstates. And since I already had this sata card, I bought this converter so I could plug it into the PCIe x1 slot.
Keep in mind that you lose the ability to connect a second NVme ssd if you want to achieve higher cstates.

How will the converter make it so the second slot does support ASPM? The second M.2 nvme slot and the PCIe X1 share the same pcie lane.
Just curious how this works then...

Are you sure BKHD version shares a pcie lane between the 2nd m.2 and x1?
The converted itself does not make anything about ASPM. I had one laying around so It was more convenient for me than buying a PCIe version of asm1166 controller.
If you plug an ASM166 into PCIe Port 11 (second m.2) slot with ASPM enabled you will get some AHCI unavailable errors and HHDs not recognized by OS. But it works with PCIe port 9 (x1 port).
