The ZS750 comes in a simplistic black and blue packaging. On the face of the box we find a photo of the unit on a dark background and right next to it there is a brief characteristics reference. On the rear side we find the same photo along with more details about its features.

The contents of the box are neatly arranged. The PSU is wrapped in plastic and on its bottom there is packing foam. Along with the ZS 750W you will get only only the essentials, namely a user's manual, an AC power cord and a set of fixing bolts:

The dark semi-glossy finish has nice quality, without any sharp edges. On the front the classic honeycomb grill is used along with an On/Off switch. The rear side does not have any ventilation holes and the cable exit is covered by a grommet.

The ZS750 includes an 135 mm fan that draws air into the power supply through the bottom. The fan is generally spinning quietly.

According to OCZ, the The MTBF of the PSU is 100,000 hours, which should be enough for every user.

The PSU has the typical dimensions for the category (150×160×86mm).

The PSU's specs and ratings are illustrated at a sticker found at the side of the device:

The OCZ-ZS750W has one +12V rail that produce an overall 54A resulting a 648Watt max combined load. The single-rail design ensures high voltage but not for anything higher than a dual-graphics card setup. Both 20+4 power and a 4+4 EPS/ATX12V power connectors are present and separated from each other, although we would like to see them bonded together, as most motherboards are designed for such connectors:

Basic parts inside the PSU include a single smoothing capacitor capacitor (390μF, 400V, 85°C) manufactured by Panasonic as well as Japanese made Nippon Chemi-con capacitors.

Below you see the length of each cable included in PSU. We think that the 24 pin ATX cable is could be a little longer. On the other hand, the EPS cable is quite long at 670 mm.

There are four PCIe connectors (two 6+2 pin and two 6 pin) with each one attached in a different length from the remaining cable. Also as you will notice from the table above there are no FDD connectors in this PSU. Finally one company decided to get rid of this scarcely used connector.

The distance among the peripheral and the SATA connectors could be also higher, and the the wires among these connectors are not sleeved:
