Aftermarket cables for Corsair HX620 psu, anything available?

[pieman109]

I want to try and improve me psu cable appearance and I'm looking at replacing some or all of the cabling, BUT, seeing as my HX620w is getting on a bit (5-6 tears old now) I'm wondering about compatibility. Is the wring different, are the plugs/sockets different or are they backwards compatible?
Cheers.

Out of interest what would be be replacing the cables with? The below models use the same connector, HX 620 is not mentioned.

Corsair Generation 2 Sleeved Cable Kit (AXi / AX / HX / TXM) - Black , available on overclockers Corsair Link
AXI Series – 1500/1200/860/760
AX Series – 860/760
HX Series – 1050/850/750/650
TXM Series – 850/750/650/550
CXM Series – 750/600/500/430
CSM Series – 850/750/650/550/450
RM Series – 1000/850/750/650/550/450

Thats the confusing bit, they do mention "generation 2" so I assume my HX620 is generation 1 maybe? I'm just wondering if they might be backwards compatible. If they are, it gives me a few more options I'm doing for a new build.
