Regardless, the input is EPS12V, so no way to backfeed from the input.
Ah, misread thought input was molex or sata. So it isn’t paralleling then. 👍

Might help.
Curious if it backfeeds the 5v or only supplies it to the three aux connectors.
You could also make one pretty easily by buying a 12v to 5v converter and installing a molex on it. Pulls 12v and backfeeds 5v back to the 5v rail (multiple 5v sources in parallel, which is fine, we do this a lot in solar with higher votlage)
Gut feeling was that if it back-fed it could cause issues with PSUs not designed for it, and they’d reduce costs by not bothering with the outputs.
We could get into floating and bonded negatives and issues relating to that, but again, I don’t expect you to have an issue here either, especially with the psu being the source of negative. It really should work just fine and be simple as that. 👍
I do like the corsair’s unit’s purpose built design. And 3.5” mounting. That is nice.
Like I said, I’ve paralleled DC sources all my life, in computers, (dual psu, combining multiple rails, backfeeding a usb charger into a hub, etc) and in solar all the time. It’s possible to have issues, but those are rare and avoidable. They are the exception from poor equipment or poor equipment matching, not the usual rule/experience.
