A soft pouch is included for all modular cables, which is a good way to keep all the unused cables organized. The set of modular cables contain:
3 x SATA (5 cables)
3 x 4P Molex (3 cables)
PCI-E (2 cables)
2 x 4P Molex + FDD (1 cables)
2 x 2 +12V (1 cable)
I like the way Enermax has labeled their cables. Excellent for a fool-proof setup.
Here you can see the EPS12V connector and two ATX12V connectors that can be transformed into a second EPS12V connector for Quad CPU systems, and the fan monitoring connector.
Here you can see that all 4-pin molex connectors have a locking feature plus it is very easy to connect/disconnect them.
