Appearance
The package comes with pictures and facts on it, another change since the OCZ purchase. Previously, PCP&C shipped all power supplies in white boxes, and OCZ is obviously a bit more concerned with the marketing angle. There are screws, a manual in three languages, and a power cord in the box. The power supply comes in a black coating we are familiar with from many other PCP&C models.
Also familiar is the 80mm fan in the back that exhausts hot air from the unit. We found an Adda sleeve-bearing fan, which can be quiet at lower RPMs but can also get very loud if necessary. We'll see if that's a concern later in our testing.
Cables and Connectors
PCP&C generally tries to position the connectors such that users have better connectivity with fewer cables hanging around. There are six Molex and six SATA connectors attached, providing users a selection of distances to the power supply. One harness features an additional floppy connector. There is a 24-pin connector and a 4-pin/8-pin connector for the motherboard. PCI-E graphics cards can be powered by the two 6-pin PEG connectors, one of which can convert to an 8-pin connector. You will be able to run an SLI setup, provided each card requires only one 6-pin connector; alternately, you can run a single more demanding card that requires two 6-pin connectors or one 6-pin and one 8-pin connector. That's not too shabby for a 500W PSU!

I´m also positive to the importance of reporting ripple figures, the standard is max.50mV ripple but lately there is a lot of psus sold happily stating 150mV ripple in their specs even though it´s out of the standard.If such companies voluntarily reports 150mV one can only guess how high the real figures are. Or how many more companies out there are a little bit smarter and state 50mV ripple even though the real figures are mabe ~200mV.
High ripple can damage many parts in the computer, lowers performance and rises temperature. So, yes, it's pretty important and should be mentioned in all psu reviews. Not mentioning it is no guarantee that the performance is really great.

50mV is the max specification on the 3.3V and 5V rails. The max spec on the 12V rails is 120mV.
