Better question: What adapter are you using?
Usually the adapter is powered by the USB side of the adapter.
Some adapters require an interface reference voltage from the serial side - but only some.
Note:
Update your info box - it only mentions a PW-2, no mention of the K4 or KV.
Dumb question:
Why do you need a serial port on a K4?
The K4 does not require use of the serial port to either jailbreak or de-brick.

Sorry I'm a complete noobie at this--I used the FT230X for the KV and was planning to use the same for the K4. I'm doing it on the K4 because I wanted to learn more about what's going on during the boot process, and I wanted to be able to poke around on an old K4 rather than risking bricking my shiny new KV.
For the KV serial hack, it required the 1.8v connection, which based on your comment leads me to believe this was a reference voltage for the serial comm, not powering the circuit. (which makes obvious sense now that i think about it)
So my better informed question would be--do I need a reference voltage for the serial connection on a K4, or am I good with Rx, Tx, and GND?
