Looking at the cable side of the PSU, you can see that the modular power connectors are all black except for two red connectors intended for your PCI Express 2.0.  The black connectors are all intended for your common power cabling.
 

At the top we see the 120 mm fan + fan grill to keep the device cooled. It's very silent actually. Here we see standard wiring, also the newer 24 pin mainboard connector.

If you look at the label closely you'll notice that the PSU can peak at 650 Watts, plus explained is the voltage distribution.

Backside: the power switch, power connector and a small LED light which will handle power on/off and safety status of the PSU.

Let me zoom in a little: when I change the angle of the camera the modular connectors become more visible.
