Hi, everyone.

Currently, i have three Boss effects pedals being powered by a Boss PSA-230P AC Adaptor.
I'm going to get a tuner pedal, so two questions came up on my mind:

1. How do i know if my Boss PSA-230P is enough to supply power to the 4 pedals simultaneously?

The AC adaptor manual states that it has a 200mA DC 9V output.
The effects pedals' manuals state that:
- current draw for the MD-2 is 18mA (DC 9V);
- current draw for the OD-3 is 9mA (DC 9V);
- current draw for the CH-1 is 15mA (DC 9V).

Would this mean that i'm only using 42mA of 200mA available?



2. What is the best connection configuration?

Connect the power supply to the daisy chain, and then all the pedals:



Or connect the power supply directly to the tuner, and then daisy chain from the tuner into the effects pedals?



Also, what are the differences between the two connection types?
What's the point of tuner pedals having that power in/out feature?



Thank you very much for the help, and a Merry Christmas to you all.

I think the power out is designed for those daisy chains that don't have a direct adapter to connect to the original PSU. Don't know that it will make a huge amount of difference either way - plug 'em up and hear for yourself!

1. your first question: yes.

2. your second question: the first diagram is how i'd do it.

nice diagrams!

yes, you are only using 42 mA.

I've found tuner power outs to be pretty noisy. I would stick with the first diagram

Thanks!
I'm not very good with Paint, but i tried to make them as clear as possible...

yeah. your good. aparently its not as regulated, or as saf from power surgest etc, which is whyp ros use DC bricks etc that cost a lot,

but running something like that or using a 1 spot is perfectly fine for the gigging guitarist. i say grab a surge protector o plug into though. it should be able to power as many outlets on your daisy chain. might just et a bit of nose.

ive ran 5 boss pedals and a digitech whammy off a 1 spot before. thats some decent amount of power needed. seemed to work fine.

I'll probably do it in the (near) future, when i add a couple more pedals to my pedalboard. Thank you for your input!
