When about 25amps at 5Volt is enough then you can consider a low cost solution by reusing the power supply of an old/outdated PC.
I have good experiences with it. Be however aware that these switch power supplies sometimes need to be loaded to work properly. So when using this solution first checkout on the internet the characteristics of the supply.
