In the described power supply, you'll find voltages of about 340 volts DC, for two reasons. First, AC is measured in RMS, which is considerably lower than the peak voltage. I.e., 120 volts from the wall swings between -170 volts and +170 volts. Second, this power supply uses a voltage doubler, so you end up with 340 volts DC inside.
