Thermaltake, as the pioneer who incorporates RGB lights into PSU, has launched the Thermaltake Toughpower Grand RGB Gold Series, coming with a pre-installed, patented 256 Colors Riing 14 RGB fan with 5 lighting modes to choose from and built-in memory. Featuring capacities ranging from 650W to 850W and 80 PLUS Gold certification, Toughpower Grand RGB Series adopts the highest quality components and fully modular design that always accommodate any mainstream build under any circumstances. One Button to Your Desired Color By pressing the RGB lighting button, the fan color can be switched among a 256 Color RGB Cycle with variants including Solid Red, Green, Blue, White, and a LED Off mode. The fan is also constructed with a built-in memory function, saving the color applied and insuring the same color selection every time you boot your PC. Power Supply Fan Face-Up Placement for Better Cooling With the face-up placement of the fan, users can freely gaze upon their patented circular 256 multi-colored RGB fan and at the same time obtaining additional performance by using the fan as a additional exhaust mechanism, repelling unwanted heat from your chassis. As the thermal image testing shown, the temperature of PSU and computer system will decrease around 3°C (5.4 °F) by placing PSU face-up. Riing 14 RGB Fan with Concentrated Compression Fan Blade Riing 14 RGB fan blade is designed for high static pressure requirements of demanding applications; the concentrated compression blade is engineered to focus the weaker, inner circle of air outward, allowing the outer section to pressurize the air. The fan blades are optimized to enhance static pressure for an impressive cooling performance. Hydraulic bearings for silent operation guarantee ultra-low noise, and the anti-vibration mounting system strengthens the product''s stability during operation. Moreover, In-mold injection anti-vibration rubber pads provide hassle-free usage for 80% protection coverage, including all four corners. Ultra Quiet Smart Zero Fan Smart Zero Fan ensures zero noise when the fan operates below 20% working load to minimize audible noise. The fan will operate when the power supply working load over 20%. A switch is provided for those who prefer the fan to spin constantly. All ripples are lower than 30mV for high stability on +12V, +5V, or +3.3V from 0% to 100% load to ensure a high quality power supply. Low ripple noise will keep your performance-critical components, such as high-end graphics cards, to operate reliably for longer. Extremely Strict Voltage Regulation The voltage regulation of the PSU is set to no more than ±2% for major rails to meet the highest performance. The strict voltage regulation of the Toughpower Grand RGB Gold is better than Intel''s standard ±5% for major rails and ±10% for -12V. 100% High Quality Japanese 105°C/221°F Capacitors 100% high quality 105 °C (221 ° F) Japanese made capacitors which greatly improve the durability and offer the highest stability and reliability. High Amperage Single +12V Rail & DC to DC Design Toughpower Grand RGB 750W Gold is equipped with a powerful single +12V rail, eliminating the limitations caused by voltage distributions, delivering the power your CPU and VGA demand in any situations. Besides, with DC to DC design, the unit optimizes maximum energy harvest for computer systems, providing the best compatibility, conversion efficiency and stable voltage output.
