Seperate 12V rails

I'm looking for a 500W+ PSU with separate 12V rails - pref. semi-modular.

Nice to have, not essential - any with optional fan control below 50% load?

Thanks!

Also there are no load percentage based fan controls, they work based on PSU's temperature.
Anything else would be bad design seriously risking PSU's endurance if in warmer environment.

The Corsair AX series do - they have a hybrid mode to turn the fan off at low loads.

How do current-limited wire groups differ from separate rails?

Good point, and huh - space requirement aside, are there any actual 12V independent rail PSUs?

That was a really good analogy thanks.

Oh - 3D printer, it's easier to have the extruder and stepper drivers on separate rails so there's not current drops when they're intermittently moving.

The PSU it came with is a no-name ATX one I don't trust.
