I'm currently using a 203w 17 amp Xbox 360 power supply and it works well for my printrbot setup. I'm not sure if your setup requires more though. Mine runs both and has really good protection. It has...
View ArticleRe: Two power supplies in parallel?
if you have a voltmeter of some kind, you should probe the resistance of the heater bed and work out that power consumption and see if it is the bottleneck. if the power numbers are approx correct...
