Neural DSP Quad Cortex Dimensions and Power Requirements
The Neural DSP Quad Cortex measures 11.4 × 7.68 in (290 × 195 mm) and stands 2.72 in (69 mm) tall. Rated 12 V, 3 A, the figure on its adapter.
Voodoo Lab measured 1.8 A and Truetone estimates about 2 A. It still needs a high-current 12 V output, which most pedal supplies do not have. Source: voodoolab.com

Power for the Neural DSP Quad Cortex
The 3 A is the rating on its adapter, not a measured draw.
Compare the real draw above with the output you plan to use, or give it its own 12 V adapter.
Will the Neural DSP Quad Cortex fit on your board
Width must fit inside the frame. Depth may hang over the front and back by up to 5 mm in total.
