| anyone know what will happen if i use a Boss PSA adapter on my chain with a current draw of over 200 mA. I am actually at exactly 205 mA. ? is it ok to go over, or will everything just shut down? any chance of damaging pedals? |

| The pedals are in no danger but the fuse in the PSA adapter may blow. |

Considering the tolerances... I would say I don't have any ideas.
You can burn your power supply or maybe you'll never have a problem.
I would never use a power supply at its nominal power, though. |

Agreed. I would give a 20% margin, just to be on the safe side. |

You should also consider if you are going to have all your pedals on at once and actually sucking out 205 mA. If not then I would have thought you would be OK. My board totals a bit over 200 mA at times but I don't ever have all of them going at once.
Hope that helps.

my solution is that im using my 300 mA adapter for that chain, and my Boss 200 mA adapter for my "lighter" line, which equals 170 mA  |

You could always go to your favorite pawn shop and ask for their BOX of EXTRA adapters and a) find a BOSS PSA for $2.00, OR b) find, say a 1000ma or 500ma 9V DC adapter and rewire a plug so it is compatible with your boss daisy chain and away you go. As implied above, most powersupplies are happier and more reliabile if they are not running at max draw, and are probably happies at 50% of their rated current draw. I remember something like this from school. There are people here who can be more definitive. |

Yes, all I mean is that the plug on the 9V side of the adapter, that connects to the back of the pedal my NOT be compatible with your Boss products so you'd need to clip the non=fitting plug off and solder the two wires to a new plug. |

The power consumption of common fx pedals doesn�t vary very much wether they are switched on or of. That�s because the fx circuit is always on and only the routing of the signal path is switched through the circuit or bypasses it. Remember that you will drain the battery with a plugged in cable even if the pedal is "turned off"
But some pedal's power consumption depends on the settings of the controls. I noticed this behavior especialy with modulating units. |

yeah good point lightburst, though I thought they consumed significantly less when they were turned off vs turned on?

| In fact it seems they often consume less when ON... That's with almost all the distortion unit I tested on this ground. |
