I just bought a makerfarm Prusa i3v (haven't received it yet but trying to get everything else I need lined up ahead of time). I have a power supply that outputs 15v almost 16, can I use this to power the printer or is it to much voltage? It's either a 30 or 40amp unit so I'd love to use it. I'm still looking for a way to reduce the voltage without effecting the current available, but not having much luck yet. I know I can buy one relatively cheap, but why buy if I don't have to. I have a pc power supply I can convert to use as well (I've done several for other projects), but it only has 15amps available on the 12v side.

Thanks
