Single rail and multi rail switch

[Aport47]

I have the Corsair HX1200 1200W 80 Plus Platinum Power Supply that has a switch to change between single and multi rail. In what situation would you switch between them? I dont understand buying a high end multi rail psu if you just keep it single. 

 

My build: 

Asus GeForce RTX 2080 Ti Strix 

AMD Ryzen 9 3950X

Asus ROG Strix X570-E 

Thermaltake 32GB (4x8GB)3200mhz

2x ssd's 1x Hdd

Single water cooling loop.

One potential reason for switching to single rail is if what you're doing is drawing enough power to trip the OCP when configured in multi-rail. For example if you're LN2 overclocking your CPU and pulling 500W+ on the CPU.

 

I'd just leave it in multi rail configuration and I doubt you'd ever have any issues with the HX1200 and that system.

Even if you're never going to need to switch it's nice to have the option and when you're paying $200+ for a power supply it's just a value add.
