Club 3D expanded its power supply lineup. Club 3D power supplies are built to support current and next-generation multi-core CPU platforms in terms of safety, power and energy efficienty. They are ideal for high end PCs and Club 3D ensures a quality user experience by testing and stressing each switching power supply to the power limit of what your PC can draw with our full line up of Nvidia and AMD based graphics cards. The power supplies have a large diameter temperature-controlled fan, that is quiet and cool for your system, ensuring reliability and stability to meet the most demanding multimedia applications and the latest game titles. Power supplies are the devices that power computers and servers. They convert AC power from electric utilities into DC power used in most electronics. The 80 PLUS performance specification requires multi-output power supplies in computers and servers to be 80% or greater energy efficient at 20%, 50% and 100% of rated load with a true power factor of 0.9 or greater. This makes an 80 PLUS certified power supply substantially more efficient than typical power supplies. In the scheme below you can see which powersupply is recommended for which graphics card (of the Radeon 7K series) or CrossFire or CrossFireX setup. You can also use the power supplies for other graphics card configurations if your graphics card complies to the power supply specifications.
