    Default Time to abandon 4 pin Molex connectors?

    Is it time to abandon 4 pin molex connectors on new power supplies?

    I have supplies that are over a decade old with no 4 pin molex connectors.

    Can we adopt an improved SATA connector first?

    What sort of connectors does the new 12V only standard use?

    I'm confused

    has 5V on the SATA connector (P34/35)

    Correct!

    Where have you been?

    ATX12VO is +12V only from the PSU to the motherboard. The DC to DC for +3.3V and +5V is now on the motherboard and standard SATA connectors are still used.

    Did you really think "+12V Only" meant that all wires and connectors throughout the PC would be +12V only?

    I was confused because I saw a SATA connector on the power supply...

    https://youtu.be/iNCfnKEoRU0 (1.38)

    On my own 12V only power supply computer (HP Compaq 8000 Elite) the whole SATA cable comes off the mother board.

    I would have thought that it would have been better if the new standard supplied ONLY 12V, rather than also 5V (even if this is indirectly from the mother board), so that in the future it could move away from SATA connectors; so yes I thought all cables on the new power supply standard would be 12V only.

    Yeah. That SATA is +12V and ground only and I have no idea what it would be used for.

    And it's that way with ATX12VO. There's a four pin connector on the motherboard with +12V, +5V, +3.3V and ground and this coverts to a standard, crappy, brittle 15-pin SATA connector.

    Unfortunately, that would require motivating multiple industries to change what they've been doing. Not just PSU and motherboard manufacturers, but als HDD manufacturers, etc.

    Also, USB is still +5V. And while Type C fast charging uses +12V, Thunderbolt is 18V. So you're going to need a boost converter there too.

    It might be wired so that it can also get 5V back from the mother board, if so, I'd say it was a very messy new standard; even if it is a 12V only SATA cable, I'd still say it was a messy new standard.

    Perhaps Aris (crmaris) can chime in?

    If your gripe is with brittle, perhaps that is just an issue with the plastic used.

    That is kind of my point, if the power supply is 12V only then the mother board and hard drives can move later (if at all), but if the power supply retains some 5V remnant (the SATA connector) then the step wise move is not being anticipated.


    My guess, the new standard does NOT allow a SATA connector on the power supply as present on the FSP prototype.
