Actually, the connections on the cable harness appear to be good as well as all the capacitors. They are not expanded and they are not leaking--and no, I am not certain. I did not consider that it might be a board issue because I sniffed the board, there were no unusual odors when the system is powered up. Visually nothing appeared burnt. The failure occurred randomly after functioning for 4+ years. It has always been connected to an Online UPS that supports AVR, and Pure Sinewave on my server rack. I am not proficient at soldering, nor do I have a microscope, soldering iron or any of the required accessories to attempt a repair. For testing purposes, yesterday, I supplied power using an external power source from a USB enclosure and it worked. SATA Ports 1 and 2 are both functional, it is definitely related to power. I am meeting with my CEO tomorrow to discuss purchasing a new NAS type system. Leaning towards an HPE MicroServer Gen11. Going from a fantasic little affordable unit to an actual server that is going to cost around CAD$4,000 (price includes HDDs). YIkes. Thank you to everyone that took the time to read and reply though. I appreciate you, your time, and your suggestions. I was hoping I could just buy a cable and move on lol.

I have looked at a lot of other 4 and 8 PIN cables and considered using multiple single SATA power connector to double connectors but I have reservations because the harness cable included with the Helios64 has those capacitors. I am not certain what their purpose is and I am concerned if I do some sort of unique solution I will damage the motherboard. Also this was being used as an offsite NAS for a production environment backup data and so stablity is essential. I've asked this question in multiple places, I am at the point that I am just going to have to order a new NAS unit that doesn't use custom cables.

I've already performed that search. The connector on the motherboard is a Mini Molex 8 Pin connector. Here is a link to the Kobol website with an image of the harness. HDD Cable Harness

Hello, Recently the HDD Cable Harness for my Helios64 malfunctioned. SATA Ports 1 and 2 are both no longer getting power/HDDs are not spinning up. I confirmed that it was power by plugging the SATA cable into ports 3, 4, and 5 on the motherboard which all function. I also iterated through the system by removing all the HDD's and testing each HDD slot one at a time. All 5 HDDs fucntion individually in a USB drive enclosure, and all 5 function in my server system and I can mount the RAID array. My question is, does anyone know how to contact the Helios/Kobol team so I can purchase a replacement HDD Harness Cable? I checked on Aliexpress and can't find anything similar so I presume that the cable is custom. Thank you.
