Geomancer... I used a solid state power supply 48 V x 20 A for about 1000 watt. It is a nice supply, fully regulated and all that. It is a Mean Well SE-1000-48 which on Amazon ran me $168. One of the guys at pinballlife.com suggested this kind of supply. I also picked up a capacitor board from Mezelmods.com and populated it with 3 large caps to allow additional surge amperage. See pinballmakers.com for instructions on this.

Solid state supplies have their plusses and minuses. Plus: Regulated, and you can pot the voltage anywhere between 40 and 60 volts. It allows you to send it a logic signal to disable the power. Switching supplies are more efficient than bulky transformers. Also it will cut power if it senses a short. Minus: It has a fan that makes noise.
