Thread: Help. insufficient power
Not sure there is a such a thing as a proper mains powered 2hp module, though if you can power via USB then there is this from Rakits https://www.rakits.co.uk/product/go/ which might let you lighten the load on the Rackbrute.
Enjoy your spare HP, don't rush to fill every last space, this is not like filling sticker books. Resist the urge to 'complete' your rack, its never complete so just relax.
