Power Supply OEM ManufacturerCWT Claims 90% PSU Efficiency Crown

This news is not only interesting because 90% energy efficiency is highly desirable. Since we have no way to verify the claim, it will remain a statement for the time being. However, the news is also interesting because the manufacturer, CWT or Channel Well Technology, is not one of the popular power supply brands. Instead, it appears to be a small and rather unknown manufacturer, which isn’t the case. It is an important player in the PSU market, which has been dominated by retail vendors that don’t actually manufacture power supply units themselves.

CWT is the OEM partner for big names such as Chieftec and Thermaltake. According to statements from a Computex representative, CWT’s business is based on OEM orders by approximately 80%. However, the firm intends to grow into the retail market as well, as it will be able to release new technology quicker than some OEM PSU customers. The first product may be CWT’s 90+ series (we weren’t provided with a product name yet), which may be the first of its kind. Other PSU manufacturers are struggling with receiving 80plus Bronze and Silver certifications ; 80plus Gold equals 90% efficiency at low and at maximum load. Hence this could be the first product to reach it once available in mass production. The new PSU also comes with a new feature : extendable 12-V rails. These are meant to avoid branching out the power cables too much by connecting one device to the next.

The 90+ series is a 850-W PSU that comes at standard ATX dimensions of 150x160x86 mm.
