And that Cable is compatible with Bitfenix Whisper M, Cougar GX-F and probably a couple of others as well...

what about this with the corsair cable?

 

in the page it says it is not compatible with rmx

Difference of Type 3 and Type 4 is the ATX Cable and that the Type 4 has Caps inside, Type 3 not.

SO You can mix Drive and PCIe/CPU Cables between the two...

the bitfenix whisper m 650 is $80 right now, while the RMx 2018 is $60

 

is the extra $20 worth it to get multirail?

 

I guess it does, or it depends

I do not think so in this case.

The higher the wattage, the more needed multi rail is...

I'd heard that before

 

according to the article: "why single rail is NOT better than multirail" multirail starts to make lots of sense at 45A, and that SCP works best under 30A. I don't know if you agree with these numbers.

 

On the other hand, on johnnyguru's article on single vs multi rail PSUs he says that another advantage of multirail mode is rail isolation, so that multi OCP is always nice to have.

IMO it starts to make sense when you can have 3 Rails at least.

And set it at 30/30/15 or 20 for the last.

Guess what is on what rail

For two rails it hardly makes any sense.

The most useful rail distribution I came up with is 40-50A on one Rail (all the High Power stuff) and 20A for the other...

But it really makes sense if you can seperate CPU, PCIe and Drives...

Yes, something like that.

You can have individual OCP set for how you need it to protect the PSU the best way.

ie for GPUs you set it a bit higher than for Peripherials...

yes, for example threadripper or skylake-x OC'd, those could trigger OCP on some multirail PSUs

 

but the corsair psus that have multi-rail OCP have a 40A limit per EPS/PCIe cable, I don't know about the other rails
