BitFenix introduced their first premium power supplies a couple of years back with pre-sleeved cables and high quality components. Now they are ready to introduce to you their newest range of power supplies that boast of extreme quality, with the world's best performance at 80+ Gold certified efficiency and up to 92% efficiency at typical loading. The new BitFenix Whisper power supply line up comes with a wide range of power options starting with 450W all the way up to 850W in 100w increments.
As the name suggests, Whisper is an extremely silent power supply with an 80+ Gold Certified efficiency. Because of the high efficiency layout and use of high quality components, the Whisper is capable of functioning with a very low noise and heat level whilst providing stable currents at high loads.
Thanks to the use of an Intelligent Fan Control Curve and a 135mm FDB fan that starts working at a much lower voltage of 3.5v the fan can operate at 500rpm ± 10%. Because of these unique features together with ultra-low noise levels and high life expectancy of the fan, BitFenix Whisper can operate at noise levels lower than 18dBA while PSU load is lower than 60% at 25°C.
Whisper is rated at a Power Factor of 0.99, and is extremely efficient with an 80+ Gold efficiency certification. With 87+ (0% to 100% load)/ 90+ (40% to 70% load) high efficiency design, Whisper saves both energy and money for the user while providing extremely stable power output at a very low noise level.
A dedicated quad rail design together with an advance voltage switching circuit from +12V to minor rail provides the best stability and output quality. Due to the use of a separate DC-to-DC circuit to convert +12V to +5V and +3.3V, the output current from the Whisper is much more stable and smooth. The main quad +12V rails on all BitFenix Whisper models are dedicated as Motherboard + Peripherals, CPU, GPU 1 and GPU 2 (450W and 550W models only come with GPU1). All of these rails have dedicated Over Current Protection (OCP) circuits which protects components from damage due to over current and makes sure any failed component does not damage other components. Whisper can deliver full power on +12V rails due to the use of practically set current load limits on different rails.
Unlike on traditional Multi Rail PSUs, Whisper have a higher current capacity on GPU Rails and other rails to support even the most power hungry graphics cards and other components based on the actual demand. So now you don't have to worry about the maximum current each rail can provide. To further ease the use of multi rail design, the user can easily refer to the labeled power distribution table printed directly on the PSU.
Performance is not the only focus of BitFenix Whisper, as not only are they built to a simplistic yet elegant design, the BitFenix Whisper models are also fully Modular. These cables are 18AWG thick output DC cables and for the CPU & PCI-E 2.0 they are 650mm long to fit in virtually any chassis. The specially designed flat ribbon-style cables and connectors feature electronic monitoring components to stabilize the power delivered to the hardware, both increasing the durability and the overclocking potential of the components. This further reduces the power drop caused by modular connections and makes sure the components get enough power to operate at optimum levels. Combined with the BitFenix Alchemy 2.0 CSR kit, the BitFenix Whisper can be showcased with high quality single sleeved cables in any build.
BitFenix Whisper power supplies use 100% Japanese Industrial Capacitors ensuring tight DC voltage regulation within ±2% and extremely long component life. Unlike standard Japanese Capacitors which are rated to work at a maximum temperature of 85°C, the Japanese Industrial Capacitors available in the Whisper series can function at a maximum temperature of 105°C. This means the noise and fluctuation of current on high loads and high temperatures levels is lowered while the lifespan of all components is increased.
