Review on Enhance Your Corsair PSU Aesthetics with the Premium Individually Sleeved Pro Kit - White | 2 Year Warranty Included by Jennings Ford

Several reviewers of these cables apparently couldn't get them to work. I have a Corsair AX1600i PSU. These cables are great for Type 4 PSUs. What these reviewers may not have noticed is that if a cable needs to be shared for a specific PSU, MOBO, or GPU, it might. They're clipped together, so you have to look closely. I also have a huge Cooler Master Cosmos C700P case. I did not use the cables that came with it. I only used cables from the Corsair Pro Kit. Everything I needed was included and they were all easily long enough and worked like a champ. They even allowed confusing routing due to cabling limitations. These are not extensions. These are the cables and that's all you need. Of course, they don't work with all Corsair power supplies. But they do have a support page and a number listed above that identifies compatible models. The only downside I would mention is that I wish they had more than one comb per cord - at least three. I have a red set. They're a bit pricey, but you get what you pay for.
