Hi Lugia,
Thanks for your detailed reply. Unfortunately, it's not what I wanted to hear, so I demand a retraction. How dare you lecture me about some made up "rules" after I put my heart and soul into that theoretical rack?
No, seriously, thank you. Is there a downside to powering the Nebulae with 5V other than needing to keep a separate tally of the power usage? According the the ER-301's website, its peak current is 250 12V+ rather than the 300 listed on MG, which would bring the 12V+ total down to 772. I understand that the consumption listings in MG shouldn't be taken as gospel, but it seems I'm painfully close to being able to safely power this little rack with the supplied power. And I admit, just aesthetically, I'd rather not have two separate "on" switches, even if - especially if - one isn't being used.
But I'm prepared to hear what I don't want to hear.
Thank you,
Tyson
