I have an electric pressure washer rated at 1650 or 1700 psi. Never had a problem with it damaging the paint. I had the nozzle as close a few inches away as well. Always use a fan pattern spray wand and you'll be ok.
K.C. tried using a needle point spray wand before on an '07 Camry wrecked fender. Only where the paint cracked and peeled did extra pieces of paint came off. On parts where the paint was good, there was no damage to the surface. His electric pressure washer is about the same rating as mine, for sure under 2000 psi.
I checked with the detailer at my dealership before I got my pressure washer and they use a 3700 psi gas. He said, they keep it about 8-10" away from the paint.
The best part of having a pressure washer is using a foam cannon with it.
