I'm not too worried about the complexity. What I *am* worried about is that your number of SATA power ports on your motherboard will become the limiting factor for how many SATA drives you can connect. The number of SATA *data* ports on the motherboard was not as much of a limiting factor because you can add data ports through M.2 / PCIe adapters.
For example, the "MSI Pro H610M 12VO" hyperlinked in the article has a manual that shows it as having two SATA power ports, and an image shows one such port connecting to a single drive. Now I imagine this is a simplified illustration and maybe each port will have enough power to supply 3-to-4 HDDs (depending on current rating of the HDDs of course), but that's still a max of 8 HDDs. Meanwhile the non-12VO PSU I use has four ports available that can each connect to 3-to-4 HDDs each, so a max of 16 HDDs, and it definitely has enough spare power to support them because I sized the PSU for that need.
- marcosdumay 3y agoWhy not get a SATA PSU just like you are adding a dara adapter?
- Arnavion 3y agoSo two PSUs / power bricks? I'll just stick with non-12VO PSUs and boards as long as I can, and if enough people think like me then mobo manufacturers will continue stalling on 12VO.
- namibj 3y agoNo, an active converter from a PCIe power connector or such to SATA power. Perhaps integrated in many sata cards.
- marcosdumay 3y agoDoes the power brick come exclusively with the motherboard connector? I'm pretty sure you will be able to get one with extra connectors for power-hungry peripherals. Your adapter board that will need an extra pair of switching power supplies. I doubt you'll even need an extra board. (Not that I expect anybody to actually adopt the standard. People will continue to drag their feet, mostly because there aren't enough gains to switch.)
- RecycledEle 3y agoA second PSU causes huge issues with currents leaking where they should not go. An adapter from 12VO to SATA power can work, or it can be a $5 board that does $2,000,000 of damage.
- doublespanner 3y agoI suspect that you will have to get add in cards or drive caddies that also do power conversion, but these already exist (although expensive). More than 2-4 drives is starting to hit a point where you should start thinking about a different platform anyway.
- dwattttt 3y agoIn the post PATA days the available data connectors all map to disks 1:1, it knows how many power connectors would be needed for them. Expansion cards could probably supply power as well as data? I suppose other uses for those connectors would need to provide shims, much like the molex shims they use now.
- jdboyd 3y agoA 12VO PSU can still choose to provide SATA power ports, and I imagine that at some point there will be PCI-E to SATA power adapters for PSUs that support 2x GPUS and users who want 1x GPU and a lot of SATA.
