InWin Announces new CB and PB power supply series New design of 80 Plus Platinum and Gold rated ATX power supplies

[Taoyuan, Taiwan, October 2018] In Win Development Inc. (InWin), a leading innovator in PC design, has today announced its latest CB and PB series of PC power supplies. These new products further grow its critically acclaimed PC power supply range for PC gamers, high-performance enthusiasts or workstation PC builders.

CB Series

The CB series are available in two, ultra-high performance 1050W and 1250W models targeting high demanding PC setups such as workstations, enthusiast and high-performance gaming PCs with up to four high-end graphics cards using eight 6+2 PCI-E power connectors. This PSU lineup offer setups both in reliability and extreme power solutions. The CB series incorporates an additional MCU that monitors digital voltage feedback and regulates the output to keep any fluctuation below 2 percent, providing a highly consistent, reliable voltage quality.

Both CB models feature an 80 Plus Platinum rating, certifying its component selection and operation is of the highest quality. The CB series exterior is constructed of strong SECC steel and features a fully modular design with all-black cabling for a neater build.

A large, 135mm dual ball-bearing fan ensures a reliable, long-lasting operation. The CB’s active fan control analyses temperature and power output to balance cooling performance and ambient sound automatically. Post shutdown, the fan remains active for an extra 60 seconds to continue to remove residual heat from inside the PSU to extend the component’s lifespan.

The CB series measures up to only 180mm in length. This avoids requiring a longer mounting area allowing more room for hardware in the PC chassis.

PB Series

The PB series are available in 650W, 750W and 850W models, all featuring an 80 Plus Gold efficiency rating. Its large, 135mm fluid dynamic bearing fan is designed for long-life operation and features a smart fan control system that includes a semi-fanless mode, whereby below 20 percent PSU power output will shutoff the fan to eliminate noise. When the power demand increases above 20 percent, it remains at a silent 18 dBA up until 60 percent  power load.

The PB series includes RGB lighting with the ability to sync lighting effects with RGB-infused motherboards. Gamers without RGB motherboards can manually activate the PB lighting effects using the rear-mounted button. Here, the user can choose from eight colors or a rotating array with an exciting breathing effect. The PB series even includes an internal memory so the user setting is retained even if the power is removed.

Both CB (Platinum) and PB (Gold) series use ultra-long life 105ºC Japanese-made capacitors and a DC-DC topology for 12V to 5V and 3.3V conversion. Both series are also backed by a comprehensive 7-year and 5-year warranty respectively.
