You may also need more capacitance in the PSU as ripple will increase when drawing more current.

Which is not a lot.
A stock F5 needs 30mF per channel rail. You may have to double this i you double the current. Let's see. |

nice build, can't wait to start mine
anyway which one is better configuration, CCCC R CC or CC R CCCC ? but it's for my aleph30 with 2pcs talema 2x18V 225VA and 12pcs 15.000uF, so each channel will be supplied by 90.000uF which already exceeds aleph30 design which is 60.000uF per channel
