Picade, 10" screen, Plasma 10 button = undervoltage

Built my Picade yesterday and having issues, most importantly is undervoltage cycling.

Config:
Pi4 8gb, official 5v 3a PSU, Retropie
Picade 10" screen
10 button RGB plasma kit

So what do I do? I don’t have any greater than 3a 5V supplies with USB C connector.

Oof, yeah, I think Pi 4 + 10" screen is running close to the limits of what a 3A supply can provide, so the flashy buttons might push it over the edge.

Powering the screen from a separate micro-B power supply is probably the easiest option?
