The Corsair HXi Series PSU's offer an option in their iCue software. You can choose between Single-Rail OCP and Dual-Rail OCP.
What is the purpose of these options? It makes it sound like you can switch between single-rail and dual-rail on-the-fly, but that can't be right. Maybe @jonnyGURU could provide insight? I'm puzzled because if Multi-rail changes the output of the connections, how do I know which connection is on which rail?
Here is the label on my 2025 HX1200i, indicating it's a single-rail unit:
