First Look

Inside the retail box is the power supply itself, user manual, mounting screws and a very thick power cable. As a budget offering, there aren't any "extras" like Zip ties, Velcro cable straps or thumbscrews but the price point reflects that.

The unit itself is solid black with decorative stickers on either side showcasing the product make, model and wattage. A power output chart breaks down wattage and amps across each rail. Here we see there are 54A and 648w available on the 12v rail, more than enough for most system configurations. The UL number E243823 points to OCZ Technology Group Inc. as the company behind the power supply. Further research points to Sirfa as the true OEM, a company that was once part of the Sirtec brand.

The 135mm cooling fan is solid black and free of any LED lighting. The fan is a Globe Fan with a model number of B1352512H rated at 0.33A, a common choice for 135mm fans used in power supplies. The fan is load controlled and features a double ball bearing design.

Looking at the power cables, we find the following connections: 20+4 pin ATX connector, 4+4 pin CPU power cable, two 6+2 pin PCIe cables, two 6-pin PCIe cables, four 4-pin Molex connectors and eight 90-degree SATA connectors (four per strand). All of the cables are wrapped in a somewhat transparent black mesh but OCZ has neglected to sleeve between the Molex and SATA connectors which admittedly looks a bit dated. The main ATX cable is a 20+4 pin design, making it backwards compatible with older 20-pin ATX connector boards. Most newer power supplies we have looked at lately have moved away from this design and offer a single 24-pin connector, but this design ensures compatibility with aging boards so that's a good thing.

We cracked open the power supply to have a look at the components within. I'm far from an electrical engineer so we simply present you with some photos to have a look at. If you are looking for a more detailed technical review, we suggest you check out reviews on this unit from some of our affiliates that are more equipped to produce such analysis.

Move ahead as we install the OCZ ZS 750w in our test system and take a look at some test results.
