All of the cables are of good length, nicely sleeved and provide flexible connectivity. The 8-pin and 6-pin PCI-E runs will help power the very latest graphics cards. There are two ATX CPU connectors with one being the flexible 4+4 variant and the other the standard 8-pin that is also EPS compliant.
The 20+4 main connector can be seen here. It is nicely sleeved almost all the way to the end of the run. This runs shared power with the MOLEX and SATA cables. There are also two CPU runs. The first, the 4+4-pin connector is exclusively on 12V2 while the other 8-pin CPU power cable is actually spread over two rails, 12V2 and 12V3. So, if you are going to use this power supply for a system with one CPU, make sure you use the modular 4+4 to ensure you draw from the one 12V output and do not affect your graphics card(s).
Here are the four PCI-E power runs. Included are two 6+2 pin and two 6-pin cables with each pair on dedicated 12V rails (12V3 and 12V4). That allows up to 18 amps per graphics card. Considering a GTX 280 uses about 15 amps, this should be more than enough for each rail to power a single GPU graphics card each. If you are looking at installing a dual graphics card like the GTX 295, you may require more than the 18 amps supplied by the single rail. A work around is to use one connector with blue striped wires (12V4) and one with the green stripe (12V3). This will ensure your card has more than enough power. If you are looking at using two, you may want to consider a different power supply with more power available on the PCI-E dedicated 12V rails.
And finally, we take a look at the standard molex and SATA cabling. These are also of generous length and will offer flexibility in almost any sized system case enclosure. Four of these cable runs are included and are connected to 12V1 which will share load with your motherboard. This should not pose an issue.
