Here's the link to the rack: 
I haven't calculated the individual draw from each row, but I'm sure I can shuffle things around as needed.
Berhinger CP1As are rated for:
+5 VDC @ 0.5 A, pins 11, 12
-12 VDC @ 1 A, pins 1, 2
+12 VDC @ 1 A, pins 9, 10
My rack will draw 1803 ma +12 V and 290 ma at -12 V, which might be too close to maxing out. I'm not too sure how some of this works, whether it's as simple as matching up the power draw to the supply rating or if there's something I'm missing in terms of individual module requirements.
New to the powering side of things. I'm getting to the point where I should power it internally, but I'm using an antique suitcase and I'd rather not cut any more holes in the thing haha.
Can anyone help me out here?
