Picade, 10" screen, Plasma 10 button = undervoltage

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

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?
