Someone sanity check me please

So I'm moving from a Corsair Type 3 to a Type 4 PSU.

Can someone please sanity check me that the only difference with the cables between types 3 & 4 is the 24-pin ATX?

I have a set of custom Cablemod cables I want to re-use and am thinking I can use all except the 24-pin?

It is what Corsair say here:

DISCLAIMER:

1. Please consider the total power consumption of the entire system when choosing compatible power supply units.

2. The only difference between Type 3 and Type 4 cables is the pinout of the 24-pin ATX cable; all other cables (SATA, PCIe, etc) are the same.

Ah missed that, thanks

Can confirm it's just the 24-pin, having done the same move and not caused anything to kerplode.

What I don't understand is why the non-24-pin connections appear different on these two pages:

Corsair® PSU Type 3 Cables Pinout

Type 3 cables are compatible with the following Corsair® PSUs: AXi (Except AX1600i) HXi HX (GOLD) RM (previous to 2019 version) Limited compatibility: Only compatible with 24pin ATX cable: AX1200 Only compatible with 8pin PCI-E, 4pin Power and 5pin SATA Power cables: CS-M CX-M TX-M...

Corsair® PSU Type 4 Cables Pinout

Type 4 cables are compatible with the following Corsair® PSUs: AX1600i (TITANIUM) AX (TITANIUM) HX (PLATINUM) RM (2019) RMi RMx SF Limited compatibility: Only compatible with 8pin PCI-E, 4pin Power and 5pin SATA Power cables: CS-M CX-M TX-M (GOLD & BRONZE) VENGEANCE-M (BRONZE & SILVER)...

On closer inspection, it seems that, for all cables other than the ATX 24-pin, the cables are compatible, in that the right voltages are on the right pins, but the actual wiring appears different.
So clearly they are compatible but I'm wondering why Corsair decided to rearrange the wiring and whether this means that "genuine" Type 4 cables are better in same way than older type 3, even though they'd both work.

This might answer your question:

Gen 3 uses a nylon sleeve and there's heatshrink where the sleeve meets the connector. Gen 4 uses paracord and there is no heatshrink on the ends of the sleeves.

Type 4 cables have an additional +12V, +5V and ground sense. Type 3 only has the +3.3V sense.

Corsair cables 4 gen vs. 3 gen

I'm looking at Corsair Premium individually sleeved pro package. I see that I can buy a type 4 gen 4-package and a type 4 gen 3-packager. What's the difference between 4 gen and 3 gen, and does it matter?
