Aimed at those looking for enduring stability and unyielding performance at an incredibly low noise level, the 500w Stronger PSU from renowned Japanese PC accessory specialists Scythe offers a second to none quality of build. Scythe's legendary passion for uncompromised specification while remaining pleasing to the ear, see this excellent PSU fully loaded with the best in quality internal components, cable outputs and connectors, along with immense air flow at an almost inaudible noise level. The Stronger PSU series features an ultra quiet Slipstream 140mm fan, spinning at a glacial top speed of 1200RPM and generating an amazingly low maximum noise output of only 23.2dBA! To further optimise air flow without generating unwanted noise, the fan spin speed is determined by system loading. Taking noise reduction to the next level, Scythe specially designed a fan grill for this PSU which allows the cooling fan to operate at very low speeds even while your system is under extreme load. Equipped with real world, useable features such as intelligent fan connectors, this PSU can also alter your chassis and CPU cooler fan spin speeds based on system loading, making sure your PC is supplied with the air flow it requires when needed for gaming and other demanding applications, but running almost totally silent when your system is at idle or under a light load, such as when you’re surfing the net, just chilling out with some great music or watching your favourite movie. Meeting ATX 12v version 2.3, EPS 12v and 80Plus specifications, this seriously quiet PSU complies with industry standards and offers over current, over voltage, over power, short circuit, under voltage and over temperature protections for your PC system. Supporting the latest video cards, main boards and other power hungry components, this PSU offers one 24-pin main power connector, one EPS 12v (8-pin) power, two PCI-Express 6+2-pin suiting video cards requiring either 8-pin or 6-pin inputs, eight 5-pin SATA, six 4-pin peripheral connectors and two 4-pin floppy plugs.
