USB Ports max out at 500ma so I wouldn't worry about that really... And My M2ATXHV is fine powering my 12v screen and 5v hub.
Slightly off topic but can someone tell me how to use a multimeter to read how much juice is being drawn? I just watched the latest MP3Car blog and they had the meter connected reading how much was being used..
I want to do this but not sure what setting to put my meter on and not sure where to put the probes. Thanks!
Also, can someone explain technically what the difference is between using a powered hub like we are talking about compared to a non powered one like this:
If you used something like the image above would your USB devices not get enough juice?

The picture you linked to is broken, but the main difference is that with an unpowered hub, your power to the USB devices is split. That is, if you can draw .5 amps to a 4 port unpowered hub, then that is all the power you get for all of the devices you plug into it. Low powered stuff like a mouse or a GPS or a touchscreen can be plugged into this but higher powered stuff like USB drives will probably overload it and won't work.
A powered hub will provide the full 500 ma for each port.
Thanks BugByte! The image shows up for me but I don't think you need to see it to know what I'm talking about anyways.. Just a simple non powered USB hub..
So Wifi cards, bluetooth adapters, and usb sound cards would be fine in those?
I dunno. Depends on how much power they need. You'll have to check the specs on them and add them up.
Probably a BT adaptor will work. I wouldn't be so sure about WiFi cards or sound cards.
n00b question. Why wouldn't anybody just use a 4 port non-powered hub? Do you really need 7 more usb slots in addition to the 10 most mobos already have?
I'd think an extension from my trunk to the glovebox with 4 inputs for ipod, blackberry etc. would be plenty good enough no?
What am i missing?
