    Default Not sure about GIGABYTE's newest drive bay device

    http://hexus.net/tech/news/mainboard...-motherboards/

    2 SATA for :

    100W / 5V = 20A / 2 connectors = 10A per connector, likely coming from the same cable even = 20A on one 5V 18 AWG wire

    Fortunately for these fuckers, 100W drawing USB shit ain't really out so far, but I would not go beyond 6A total for that wire

    Seeing how all connectors supply only one 5V wire, save for the ATX Main, they'd need to go with a PCI-e connector and 12V -> 5V buck regulator, or 3+ connectors (4-pin peripheral or SATA).

    They're betting on nothing people would plug into their PC USB port is going to draw more than 20-or-so watts anytime soon...

    Doesn't make them any less retarded for claiming it can provide 100W though.

    Besides, what's the power transfer ability for the contact pins on the USB port itself? Can't be more than 5A per pin...
    Careful what you wish for... You just might get it.

    Where do you see that they are only using 5V? Why not the 12V from the two sata connectors? 100W USB 3.1 is 20V anyways, and not 5V, so 12V is more logical.

    6 pins PEG connector is a better option of course, but using the 12V from two sata connectors isn't instant fire.

    they use +5V for USB. This whole Power Delivery aspect of USB 3.1 is nuts going 100W max., even with external PSU adaptor.

    But this bay uses PSU connectors, not it's own external PSU, for cost.

    The prob is not the SATA connectors per se, but for PD of 100W you need 4 5V wires = 4 drive cables, with nothing else connected to them. And guess what end users would do instead?

    This thing has to have internal step up if they put 100w type C there. Hell that's be nice, I can charge my laptop in it then!

    I'm with Mask here. We don't know that they're just loading +5V here, do we? They could have D2D inside that box that take power from the +12V.

    I had to change the name.

    I don't like calling out any company, but the biggest thing was the use of the word "retarded".

    I'm far from politically correct, but I have a mentally challenged brother and my wife is a special education teacher by trade. We try not to throw the word "retarded" out there unless we're talking about a car's ignition timing.

    Ok, but even with D2D inside, you still have the AWG wire problem
