The Pod34X is 34HP wide and has extra room to fit even the deepest modules (2.16" / 55mm of available module depth). The built-in power supply has four power connectors and can be daisy-chained to other Pods. More power connectors can be added with the Multi Power Cable accessory.

This Pod requires a power brick (not included). 

Or, if you already have a Pod and power brick (or a Row Power module) you can use a barrel cable to daisy-chain power supplies.
