    Usb hub power source?

    What are people using for usb hub power source? I have a powered 2.0 hub upfront and a pcmcia usb/firewire card that has a ac adapter as well. I am using a fair amount of power hungry devices so I need the power (my sound card won't run off the hub unless its powered. Last year I used a power inverter and the ac adapter, but every time I had to crank for whatever reason I would royally screw up my system.

    The hub wants I think 5 volts and the adapter has 10 - 13 I think on its adapter... sorta strange. I will also have an external media drive which runs off of 12 volt so I was thinking of a 12 volt conditioned supply and using it for the adapter too, but what about 5 volt... a point of load?

    5v line from a HDD power connector on the PSU.
    Have you looked in the FAQ yet?
    How about the Wiki?

    Another Solution...

    I'm using this 5V regulator from Radio Shack to power my:
    • Hub
    • DVD-Rom
    • Touchscreen
    • USB Camera
    • GPS Receiver

    Keep in mind, though, that it only handles 1A (x 5V = 5W) at most... So don't overload it.
    Put it on a heatsink or screw it into something metal.

    holy crap... thats alot of stuff on that rig. I built a supply for my liquid cooling system using those and a 12 volt one, but they are rated 1 amp... my hub alone is rated 2.5 amps... then my media drive is rated at 3.5 I think... thats alot of them... I decided I would probably overheat them in the summer and start loosing devices which is worse then dealing with the power inverter.

    thoughts on my calculations? They way off?
