Bob,
The KX3 is a direct to baseband SDR receiver, so a good power supply is
a measure to prevent noise and hum.
Wayne's recommendation (and mine) is to use a well regulated linear
power supply. There are many 4 to 6 amp linear supplies available. That
current rating will allow you to use that supply with the KX3 in
addition to several shack accessories.
The Astron 5A or 7A would fit the need nicely but a larger supply would
work nicely too (put it on the floor under the desk).
73,
Don W3FPR

Elecraft does not sell a 13.6 VDC "AC Adapter Power Supply" for the KX3. This
is a very common product and there are many
alternatives on the market. Most of us have drawers full of these AC adapters.
However, most are cheap, noisy switching power supplies.
Is there a recommended KX3 power supply that provides sufficient current to
obtain the full 10 Watt output and yet not add to the nosie floor of the
receiver?
