    Correct.

    Like I said earlier, it's 4.5A per rail. 1.5A per pin. Each "rail" uses three pins. You have three +12V pins, three +5V pins and three +3.3V pins. That's 4.5A for the +12V, 4.5A for...

    I am talking about the device side connector. One more time: The weak link is the SATA power connector... Device side.

    And fan motors use +12V while Corsair RGB lighting strips use +5V. So you...

    4.5A. 4.5A per connector. That's why I keep telling you. :D

    Each SATA connector can deliver up to 4.5A of any given voltage before it gets too hot and melts.

    As for the Commander Pro: Yes. ...

    No. I'm only talking about the device side connector. 18g wire can handle a lot more than 4.5A.

    No. That is exactly NOT what I said. :D

    Only the SATA connector is rated at 4.5A. The 18g wire and the connector at the PSU should be able to handle the full 25A.

    It's not. Besides, it's only used for +5VSB.

    Yeah.. I actually had a problem with transformer saturation causing the PWM FETs to blow up in a PSU many years ago. I think it was an Andyson unit for BFG. Luckily, we caught it in DVT. I...

    No. You misunderstand. Transformer saturation is a thing. I agree with your assessment.

    They won't melt on the PSU side. That connector has larger pins that are meant to deliver power to a multitude of SATA connectors on the other end of a cable.

    They melt on the device side.

    It doesn't until the connector melts to the point where hot touches ground and you have a short.



    25A X 5V = 125W. Not 130W. The 130W is for the +5V and +3V combined power. That means you...

    Depends on the PSU.



    No. Typically the SATA connector at the PSU melts. That's why we saw that as a common problem when people would use SATA for PCIe adapters for cryptocurrency rigs.

    +12V, +5V or +3.3V.

    Depends on the device.

    Like, a SATA HDD uses both +12V and +5V. +12V for the motor and +5V for the logic.

    An SSD only uses +5V because, well... it's solid state.
