Is there any reason why I should NOT use this as the PS?"

Hmm... 12V at 500 mA is only 6 watts-- perhaps the 14 watts
refers to the power drawn by the wall wart while supplying rated current.
If that's the case, then I wouldn't use it for the K3 (mine with one Rx and
no antenna tuner draws one amp. at 14V.)  My K2 QRP version with most
accessories, including DSP, draws about 300 mA, so the wall wart might
power your K2.
