With the ZS series OCZ adresses the value oriented users that seek for a branded but affordable PSU to power their systems and don't care about characteristics like modular design, DC-DC converters, Gold efficiency etc. In order to keep down the price, some compromises had to be made so the platform does not use cutting edge technology, on the contrary it uses an older but proven design. Besides the average ripple suppression on the +12V rail and the small distance among the SATA and peripheral connectors the main problem of the ZS 750W is its price, which brings it to the $100 category where someone can find similar capacity units that utilize modern designs and so yield better performance.

To sum up, with various mail in rebates you can find a ZS 750W in the US for only $75, a price that boosts price/performance ratio and renders it a really good deal for a mid-range system. At this price I can recommend the ZS 750W without any hesitation, however I had to give a final rating based on the $99.99 price tag since mail in rebates are not permanent.
