Thickest Power cord with Power distributor?

Hello everyone,

I have a question regarding the usage of power cord in my system.

Let's make it simple with fewer components.

I have an Ansuz C3 Power Distributor 

1 Zavfino Silver Dart power cord (thicker cable, small awg)

1 Ansuz P2 Power Cord (regular awg/thickness)

1 Integrated class A (about 400w consumption when in use.

In theory, where will you use the Zavfino cable? From wall to Power Distributor because of the higher current that can deliver to all the components?

Thanks 🙏
