Thread: System 100m Power
The CP1A can power two rows comfortably. Not sure about the uZeus. I think there's some kind of booster adapter for it. Look into that. In any case, if you want to position the PSUs where they are now, you'll need flying bus extensions to reach the two upper rows. The ones provided with the units won't reach.
I don't know about the uZeus, but the CP1A is designed to be placed on the left for comfortable connections. Either that or upside down on the right.
