The mini is great without a lpsu, using just the supplied smps. Used a Sbooster botw p&p power supply, , and the results were phenomenal. Found out Innuos says there is no warranty support if power supply is found to be at fault. Sent it back to the dealer. Went with a zenmini lpsu as advised by the company. Am waiting for delivery, ordered one last week. But, yeah you gonna wanna save and get the lpsu.
