Antec does a great job with connector availability for the HCG-620. It is a little bit overkill, but covers just about every angle you could think of for the 620W power supply. The obligatory 20+4 pin and ATX 4+4 connectors are there. After that you are given a pair of 6+2 pin PCI-E connectors, six Molex connectors, six SATA connectors and a single FDD connector.
Rail distribution is kept simple with a single 12V rail.

Some of the newer power supply designs are getting incredibly tiny. If it wasn't for the 135mm fan, Antec could have used a much smaller enclosure for the power supply.
There is a single Nippon Chemi-Con capacitor on the primary side.
Nippon Chemi-Con capacitors are found on the secondary side as well.
Antec chose the ADDA 135mm fan, model ADN512MB-A90, to cool the HCG-620.
