MOTM

I've begun building a cabinet that will hold 20-25 MOTM modules  
(including an MOTM-650, which the site description says may draw  
575mA +/-15v). I believe that one MOTM-950 Dual Power supply won't be  
enough for the +/15v side.

What would be better? Installing an MOTM-900 Dual Power supply  
(outputting +/-15v @ 800mA) *and* an MOTM-950 Triple Power supply  
(outputting +5v @ 3A, and +/- 15v @ 400mA) or... replacing these with  
one upgraded Power-One Triple Power supply (such as model# HCBB-75W-A  
which outputs +5v @ 6A, +/-15v @ 1.5A)?

Cheers,

Cecil
