I'm building a little Neo-Geo cabinet and am trying to figure out how big of a power supply I need. Here is what I have and how much power it needs:
2.0A 12v for Monitor
1.5A 12v for Audio Amp
0.7A 12v for CCFL Marquee Light
0.5A 12v for 2 80mm Case Fans
1.0A 12v for PCB
3.0A 5v for PCB
2.0A 5v for CGA2VGA Board
0.5A 5v for A Few Button LEDs
So do I just add everything together and look for a power supply that can output 5.7A 12v and 5.5A 5v? What would happen if I run a power supply only rated at 4A 12v?
