It has been some time since we reviewed a Zalman PSU, so we responded immediately when they asked us to test some of their new models. The truth is that as the competition increases prices drop while quality improves, which benefits all of us consumers. Most companies might use the same platforms for their offerings since there are only a handful of good PSU manufacturers; however, that doesn't mean there won't be any differences between products, since each company decides their pricing strategy and has a say in the quality of parts used. Some vendors might, for example, use nothing but Japanese capacitors while others who want to lower production costs will only use Japanese caps in the APFC converter. Some larger companies (e.g. Corsair, EVGA, be quiet!) also have PSU engineers they can ask for modifications in the design on their payroll, which allows them to offer something different from those competitors that utilizes the same platform.
It also has a +12V rail only and Zalman states it to deliver its full power continuously at up to 50°C if need be. We are going to verify their claim during our hot-box tests and will push it even further by dialing in a load that exceeds its capacity by 10% (1100 W).
