PSU Cable Compatiblity

[vtechhiltz]

I am sure this has already been asked, but I have had a hard time trying to find a definitive answer. I know that is considered bad to interchange psu cables, but in my sleuthing, I found the Corsair PSU Cable Compatibility list. I am running a RM750x (2018) w/ custom CableMod cables (EPS, 24-pin, PCIe, SATA, Molex; cause pump/res combo in system uses molex for power and PWM for pump speed) and am upgrading my 1660 to a 3090. Based on on my wattage calculations and allowing for power spikes, I need a 850w PSU, if I upgrade to a RM850x (2021) power supply, can I still use the custom cables I have already in my system or do I have to order a new set? I know that Corsairs compatibility list says that all RMx series use type 4 cables (for 24-pin, PCIe 8-pin, and EPS 4+4-pin) and type 3 for everything else, but that list is damned confusing at the best of times, and only shows cable compatibility for RMx (2021). Even their legacy compatibility list is useless. I just don't want to spend more money then I have have to to make this upgrade work.

does it say on the cablemod website that you can do this? Or on the corsair sight does it say that directally? I remember seeing something like that but make sure otherwise your risking your whole PC.

ideally you shouldnt but both are intercompatible according to Cablemod.
