The example board is the calculator's opening board: a tuner, a compressor, an overdrive, a distortion, a delay and a reverb, drawing 293mA.

03How to read it

Outputs is the most pedals a supply runs, one per jack. A daisy chain splits its one jack across the board with a cable, so current is its limit instead.

DC capacity is summed from the per-jack ratings each manufacturer publishes, not the headline figure on the box.

High-current jacks lists the outputs rated 250mA or more at 9V, by rating. Big digital pedals need one each and a rating to match: a Chase Bliss MOOD MkII (270mA) needs a jack rated 270mA or more, a Strymon BigSky 300mA, an Eventide H9 Max 500mA. This column decides how many of them a board can carry.

Voltages lists every DC voltage the supply offers. An 18V pedal such as the MXR M68 Uni-Vibe needs an 18V jack. Jacks that switch to 12V or 18V on a fixed wattage deliver less current there; each supply page prints the figure at every voltage.

Open any supply for the jack-by-jack breakdown, the board it suits, and the pedals that need its high-current outputs.
