How it\'s wired. With my wiring, the USB wires are heating up to around 200-300F.
Am I using the right voltage?
Is the iPad demanding too much power? The PSU worked fine after the incident.

I expect the iPad can draw a fair amount of current, and the ATX PS
could certainly supply it. How thick are the conductors?

I wonder what the actual voltage is.

Presumably 5V, unless you\'re thinking that it\'s drawing too little
current for the ATX PS to be stable.

Some \"USB\" (irony emphasis on the U) cables are specifically
resistive, to limit current.

You may find the PSU requires a heavier load on the supply than you are
providing.
Putting an ammeter in series with the load to give you a rough idea of
the amount of current flowing would be a good idea. Likewise, the voltage
DROP across the cable\'s length.

If you disconnect iPad from your \"adapter\", there should be NO current flowing

I\'ve seen gadgets that come with a specifically resistive USB power
cable and warnings to use only that one. I don\'t have a link.

In that case it isn\'t a USB cable. Its something else with USB-style connectors.

I\'d expect that an ATX switching supply might make a lot of voltage
with a light load.
OP could measure both.

I don\'t think computer supplies work that way. They either regulate or shut down.

In an ideal world, certainly.
But who knows what some cheap PS from China might do? Not that I\'m
saying that the OP has such a PS, but anything is possible.

no, random Chinese dothats convinnietly powered by the 5V from a USB port is not USB
