Question Swapping cables on a new psu of the same brand?

[MBurner]

Installing a new psu in a few days and I was wondering if I'd end up having to go through and replace all the connected cables. I saw warnings that it might fry your system etc because of pins not being standardized. I'm trying to minimize just how many things I need to mess with so I don't end up breaking anything myself.

I'm upgrading from a corsair CX-M series to an RM-e and found a reference here https://pc-mods.com/blogs/psu-pinout-repository

So there's two situations here depending on the year the new was manufactured, I have no clue how to tell this myself. Assuming the model is newer that means it uses type 4 cables compared to the old psu's type 3.

For the motherboard cable I need to replace that anyways as the CX-M is built into the unit. There's some differences in the wires for the GPU but the voltages are identical, if that needs to be replaced it would be easy enough to access. For the CPU and SATA though the voltages and wiring look identical and wouldn't need to be replaced?

Even after all that I'm assuming the answer is going to be "just replace them all"

Use ONLY the cables that come with the new PSU.

Period.

You can use the current cables because the pinout is the same. Only difference between Type 3 and 4 is the 24pin.
