I was waiting for someone to give that answer.
why not use real arcade parts. 5volts @ 15amps.
You may also benefit by running multiple wire paths for your leds, rather than one continuos circuit.

heres a good deal on an arcade power supply. I have ordered many times from this place and have always been pleased.

Makes sense to use an arcade power supply. I have all 4 led systems on separate circuits rather than in one. Once I clean things up it'll be much nicer inside the cab. Cab is less than 12"w inside though so heat builds up quickly.

I got a PS from Twisted Quarter. Not sure what the knob you can turn is used for or even what the -5V is for. Never used an arcade PS before. I'll primarily use the 12V it looks like for the leds that I have.

The knob on those power supplies is usually to adjust the 5 volt line. Over time, the 5v line will sometimes degrade and some boards are sensitive to how much power they're supposed to get.
The -5v line is there because some older games require -12v and -5v.
