Well I have been using an old gaming PC as NAS after it’s GPU died, and even though it has served me greatly, it’s a power hog. Also CPU is pretty old to do any transcoding or AI stuff. I have scored a mini PC with Intel N5105 for free, and its quite power efficient. Also it doesn’t have SATA, but two nvme m2 slots, one of which can work with these m2 Sata adapters (asm1166 chip with 6 SATA ports). Now minipc obviously can’t power up the 5 hardrives, all 3.5" SATA, so I need an external power supply. minipc got it’s own adapter brick, so is there a similar adapter that can work for drives, or I have to get a PSU. But then again, If I am getting a PSU, I wonder if I could power the MiniPC off it as well.
I did came across this , and was wondering if this could be that would work for me.
If I’ve understood you correctly, I think you’d need to link 0VDC / GND between both the system PSU and the HDD PSU, otherwise you’ll get variable reference voltages for the data lines
Happy for someone else to shoot this idea down in flames, but I think the data is using absolute, not differential voltages
