Will power supply give enough

Howdy,

I have been working a building a DIY modular synth. So far I've got a Music From Outer Space Sound Lab Ultimate and 16 Step Sequencer (each housed in separate cases) as well as a Cat Girl Synth Super Psycho LFO and am working on finishing up a MFOS Noise Cornucopia and CGS Dual Wasp Filter and Utility LFO (theses will be housed in a traditional modular style'; rack rail system with separate panels for each module).
For the power supply for all of the above, I have been using a +/-12 volt power supply from Futurlec which uses a 14 volt AC power adapter: http://www.futurlec.com/Mini_Power_Dual_12V.shtml
I'm wondering if this would be enough to power several separate modules. The case I'm working on should fit about 7-13 modules (have two sizes of face plates i'm going to use) and will be a mixture of MFOS, CGS and maybe some Oakley PCB modules.

Add up the current requirements for each item...The page says it will supply up to 1 amp...although that will depend on the transformer you are using also.

I'm guessing it probably won't be enough for all the modules you listed.

The one you linked to is a 'switching' supply - you may want to consider something like a 'Power-One' or "Condor" linear supply...
