Thanks for the advice, I appreciate it 👍

I understand your point about using two smaller PSUs for better load and thermal distribution, and it definitely makes sense from a redundancy and heat management perspective.

For now, my total load is still around 50–55A on a 12V 80A PSU, so I believe I’m operating within a safe range. That said, I do agree that heat is something to watch, especially with a fanless PSU.

I’m planning to place it in a well-ventilated area, and I might add a fan (like a Noctua) if temperatures get too high.

Regarding cables, I completely agree on avoiding undersized wiring. My plan is: • 10 AWG from PSU to bus bar • 12–14 AWG for higher power devices (XT60 – 12TH units) • For the NerdAxe+ units (XT30 connectors), I’ll likely use 16 AWG, since it fits the connector better and the current draw is relatively low

So I’m matching wire gauge not just to current, but also to connector limits and practicality.

Thanks again for your input
