  • Powered USB hubs

    I have and and but im going trying to find the answer.

    Please someone one help me with this. I have a powered usb hub. I understand that i need 5 volts to power it. Im pretty sure i can get it off my m2-atx power supply. My question is how in the hell do i do that. Do i just get a plug and cut the wires and hook it up to the power supply? if so where do i hook it up on the power supply?

    Tap into a 4-pin molex connector (otherwise known as a HDD power connector).
    Red = +5v
    Yellow = +12v
    Black = Ground
    Have you looked in the FAQ yet?
    How about the Wiki?

          couldn't tell if you'd done it already, but yeah, if you're not going to use the hub in the house anymore, yeah, just cut the plug and wire it in. Just make sure your polarity is right.

                        well your ac power adapter should say which part of your plug is positive and which is negative, so taking that, and a multimeter, check the wires (once you cut the plug off from the adapter, and see which wire matches up with the positive/negative respectively. use the continuity/beep/short setting on the multimeter.

                          intersting... but what if you need something like 8 volts, where do you draw this from... or would you use the 12v line with a resistor?

                            What would you possibly need 8V for ?

                              I have two usb hubs, one uses an 8v input, the other 3v... hence my question!
