Inside the retail box is the power supply itself, user manual, various modular cables, two Velcro strips, a power cable and 3-pin fan adapter.
The power supply is solid black with a textured style paint that looks rugged. One side of the unit (the side that would likely face outwards when installed in a case) features a large sticker with the product name and Zalman's logo on it. The opposite side has a few small quality check stickers that could easily be peeled off. The power layout table sticker can be found on the top of the enclosure.
The back of the ZM850-HP features a full honeycomb-style perforation for maximum airflow. Here we find an on/off rocker switch and a power cable connector.
While most of the cables are modular, we see that the ATX power, CPU power and a set of PCIe cables (6-pin and 6+2 -pin) are hardwired. Additionally there are modular connectors for three sets of SATA cables, three connectors for ODD/HDD/FDD and two connectors for PCIe cables. Each of these connectors are labeled to limit confusion, although each connector type is different so it would be impossible to plug a cable into an incorrect connector.
The argument over modular vs hardwired has been ongoing for years. Truth be told, hardwired is technically “cleaner” as there aren't any “breaks” in the line but with modular, you are afforded so much more flexibility and much better cable management. If you are an absolute power supply junkie, I suspect it will be hardwired-only for you, but I've personally never had a problem with a modular system in a PC that caused stability issues nor do I know anyone else that has.
Let's continue on and have a look at the included modular cables and open up the power supply for a look inside.
