It should be fine to run the KPA500 at reduced power using your existing 15 amp outlet, unless you have a lot of other stuff plugged in.
No power reduction is required -- let's do the simple math. The KPA draws about 10A at 120v keydown. That 12v (probably 13.8V) supply shouldn't draw much more than about 2A when the K3 is driving the KPA500, because the KPA needs less than 30W to get to full power. The 13.8V supply should draw no more than about 2A with the K3 barefoot at full power keydown.
