I have also received my N305-DC board and wanted to give some hints (and power measurements).
My Hardware:
- N305 CWWK DC board
- 32GB DDR5
- 4TB Lexar 790 nvme ssd
- 2x Western Digital Blue 5TB (connected via JMB585)
- 2x Western Digital WD120EDAZ 12TB (connected via JMB585)
- 1x Seagate Exos X18 (connected via internal Sata Port)
- Powered via Chicony A17-180P4A 19,5V, 180W Brick
I'm running unRAID. When all drives are spun down and the cpu is nearly idle I get about 18W-19W power usage. And of course I cannot get below C3 verified with Powertop 2.15, but it's okay actually.
CWWK told me that there will be 2x 4-pin ATX to 4-pin molex inluded, but the were not and they are currently sending them my way. Because I didn't want to wait till they arrive I made my own adapters with some sata power cables from my corsair psu that I am not using (similar to these:
Premium Individually Sleeved SATA Cable, Type 4 (Generation 3) - Black (corsair.com)). I exchanged the 6 pin connector with a 4 pin atx connector that I took from
these cables and I am now powering all 5 drives (and I also tried 6 drives) from the two 4 pin ATX ports labeled SATA_PWR1 and 2. The pinout can be found in the Topton N305 listings at AliExpress.
No extra PSU needed, all from one brick. Seems to be running solid, even with all drives in full motion and about 100% CPU.
