The Cooler Master Silent M bundle is nicely packaged and comes with everything you need. Cooler Master even tosses in a couple silicon pads you may use when mounting the PSU to help dampen vibration.

The flat cables are what makes the Silent M unique. These cables are thinner and lighter than any other PSU cable I've seen. These cables will definitely be a big hit for those who meticulously rout power cables through their computer case. They are easier to hide and far more flexible. 

Above is a photo of the cables and connectors. Cooler Master has gone with a flat 4-pin connector for the SATA and 4-pin accessory cables, and a 6-pin rectangle connector for the PCIE cables.

Here we see the SATA and 4-pin connectors. There is no cable wrap or heat shrink on the cables so these flat cables are extremely easy to bend for superior cable routing.
