Gold-Certified Efficiency And Semi-Modular Cabling For Low Energy Use And Easy Installation
TX Series semi-modular power supplies are ideal for basic desktop systems where low energy use, low noise, and simple installation are essential. All of the capacitors are 105°C rated, Japanese brand, to ensure solid power delivery and long term reliability. 80 PLUS Gold efficiency reduces operating cost and excess heat. Flat, sleeved black modular cables with clearly-marked connectors make installation fast and straightforward, with good-looking results.
80 Plus Gold-Certified Efficiency
The super-efficient operation of the TX Series semi-modular results in lower energy use and lower operating costs. Since it generates less heat, the fan doesn’t need to work as hard, and you’ll enjoy near silent operation.
Modular Cabling With Clearly Marked Connectors
The flat, sleeved black cables are semi-modular, so you’ll only use the cables you need and you’ll get great-looking results. The clearly-marked connectors make installation fast and straightforward.
