    Well, to be honest: Without opening up one of those and take a serious look at what they've done, we can't say anything about it...

    Or maybe we should test it with a 100W or so device??

    Option B please!

    Do the test using a Gigabyte PSU and then send it back for RMA afterwards.
    Careful what you wish for... You just might get it.

    Do you? Voltage up, current down?

    Well Type C 100w is 20v @ 5A.

    But I personally think that gigabyte would use the 12v of sata for the higher dc-dc stuff, and 5v for the other stuff....

    Factoring the notorious inefficiency of stepping up dc, we'll say ~120w, by then you're easily drawing 10a+, so say 5a per 12v connector on the sata cable.

    Theres actually a better one on the market IMO. The asus UPD panel, and it uses up one of those irritating useless sata express ports.
    https://www.asus.com/Motherboard-Acc...-31-UPD-PANEL/

    Not to mention you can take the board out and use it in your pc as a expansion card . It uses two molex connectors, something I feel safer than two sata, but hate because molex 4 pin connectors should die.

    Also, we could buy that, take it apart and return it after thoroughly examining how it works

    EDIT:



    If you look at that image, on top there's clearly a boost converter.

    It honestly sounds all stupid and all, but I own a dell xps 13. Charging that thing with type c is SO Sweet, even though it only uses 20v@3a. I might actually get one of those asus upds now, thanks

    20V? They couldn't go with a more standard and more widely used 24?

    People these days...

    I would not draw 8A 12V via 18AWG.

    And they wont have utilized all SATA wires to get current down by implementing 3.3V & 12V DCDC to 5V besides 5V.
    Plus the inefficincy, as ridgid pinted out.
    And for Asus, SATA or Molex is same, they use typically same AWG (18/20), but theirs looks decent. Still, would not want it in the hands of end users.

    Because you would not wanna push more than ~5A continuously, depending on the ambient temp. First, the first connector would melt, not the cable itself.

    As a rule of thumb for you:

    18AWG = 4-6A 12V
    16AWG = 6-8A 12V
    14AWG = 8-10A 12V (with higher-temp plastic connectors) (SATA can't do 14 anyway, PATA can, I am not sure if SATA can do 16, seems unlikely)

    We checked that at E looong ago, when I wanted to do a single PATA cable with 14/16AWG for TEC/Peltiers.

    BTW, for the multiple inputs into 1 output, that won't work without high-tech, as each DCDC stage would normally provide inconsistent output like 4.9+5.0+5.1V and only 5.1V would be drawn from the USB device. You would need a heck of VRM+xyz design to regulate them into 1 voltage

    I guess no PSU has such a cabling, right?
