Hi there,
I’m new in this world and I would like to know if something wrong with this :
I bought an doepfer p9 psu3 case
Wich is
+2000ma +12v
+1200ma -12v
4000 ma +5v

My configuration is
1520 mA +12V
| 838 mA -12V
| 0 mA 5V

Does it feet or am I wrong ?
For me, I can understand this :
My configuration consume :
1520/2000 +12v
838/1200 -12v
0/4000 +5

Thanks for your help

No, that's fine. While you should always have extra current capacity in a power supply (mainly due to inrush current values on power-up), your total module draws are pretty much within the "safe" figures to avoid an overload.

Thanks Lugia,
Yesterday night after played for an hour,
i had a fuse who was burned ... That's why I asked it :/
I don't really know whats happened.

Anyway, thanks you :)

A power supply fuse? I'd get inside that cab if I were you and see if there's not something shorted or misplugged on your power bus or module ribbons. That's more likely, given that you got the synth turned on and used it before the fuse popped.

I checked everything and everything was in a good way :/

I think Lugia alluded to this, but I'll go into a tiny bit more detail:

When you first power on your case, there's a spike in current. Everything is snapping on all at once. Your modules might draw a certain amount of power once they are on and warming up. But the instance that you turn on the case... spike.

This is especially the case if you're using tube gear for example. Manufacturers like Erica created a line of tube modules and part of the work around was a secondary power supply to handle the additional overhead in power when turning the module(s) on.

Are you relying on Modular Grid to tabulate your amps or have you worked this out for yourself? Some modules on here have the wrong power values and some don't have any at all. So don't take what you see on MG as gospel. Do the math yourself and see how close you're pushing to the maximum. You can get the specs directly from the manufacturers.

A fuse is your last line of defense from some really nasty outcomes (including a FIRE). It's worth the time to investigate. Depending on your set-up... you just might need a larger power supply... or have a bad module or bad power supply.
