Can I safely run 4x H90s on an Eventide Powermax by Cioks power supply? Would there be any issues with the startup current mentioned? In theory could you safely run 7?

Must be quite a rig with 4 H90s!

I don’t know if the Eventide Powermax will provide enough current. It appears that at 12 volts, it provides 500ma for each output, instead of the suggested 600ma. I use the True Tone One Spot CS12 and it can handle up to 3000ma which is automatically distributed across all available outputs and has 4 12v outputs.

I have one and it’s been flawless.

The Powermax may work if you start up each H90 separately, but that’s a wild guess.
