Would there be any problem connecting an internal SATA drive using an old PC Power Supply for its power and connecting to an external SATA port on a laptop? Would there be any voltage conflicts?
I just had a motherboard die and need to get some data off the hard drive. I don't have another computer that I could just drop the drive into, but my laptop has an external sata port.
The 5v power brick needs to be at least 1 amp of output, otherwise it will require USB power also.

Yes, it's possible to use an internal SATA 3.5 HDD powered by your independent power supply. There is no extra circuitry as far as I know, and the only thing you need is the SATA to eSATA cable.
If you have an eSATAp port, you can just use a compatible cable and it will provide power directly from the port.
Here is a picture of an eSATAp to SATA cable which provides direct power from the port.

The easiest would be to buy or found an IDE/Sata to USB cable. They are plenty of them at various prices, I bought one for cheap on eBay. They usually come with an external power supply (with a Molex plug and a Molex-to-SATA-power adapter).
Here is an example:
Even without this and if you can use your power supply to deliver voltage to the SATA drive, I suppose your laptop has a eSATA port, not a SATA port. You'll also need a eSATA-to-SATA cable then.
