Introducing you the newest line up of BitFenix power supplies that boasts of extreme quality and world’s best performance with 80+ Gold 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 850 incrementing by 100W.
As the name suggests, Whisper is an extremely silent power supply with an 80+ Gold Efficiency certification. 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 while providing stable currents at highest loads.
Unlike regular PSUs, Whisper M comes with a 140mm FDB fan that starts working at a much lower voltage of 3.5v the fan can start working at 500rpm ± 10%. Because of these unique features together with ultra-low bearing noise 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+ (20% 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
Generate up to 80% less heat and consume 30% less power than standard PSU’s. BitFenix Whisper also fully supports Intel C6/C7 Sleep States which consumes very less energy when the system is at sleep. With LLC, Active PFC & DC-to-DC circuit with an 80+ gold certificate, BitFenix Whisper Power Supply saves energy and your environment while providing unmatched power quality for your computer hardware.
A dedicated quad rail design together with an advance voltage switching circuit from +12V to minor rail provides the best stability and output quality. 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 to keep your High-End-components safe all the time
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. This increases the system stability as well as the durability of 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 with a dynamic power delivery.
To further ease the use of multi rail design, user can easily refer to the labeled power distribution table printed directly on the PSU to know how much power each rail supports. Connections are also individually labeled with the dedicated rails to connect the correct cable to provide sufficient power.
Performance is not the only focus of BitFenix Whisper, built to a simplistic yet elegant design BitFenix Whisper models are fully Modular with flat ribbon-style cables. These cables are 18AWG thick output DC cables and for 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 components to stabilize the power delivered to the components increasing the durability as well as 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
BitFenix Whisper power supplies uses 100% Japanese Industrial Capacitors ensuring tightest DC voltage regulation within ±2% and longest component life. Unlike standard Japanese Capacitors which are rated to work at a maximum temperature of 85°C, the Japanese Industrial Capacitors available in Whisper can function at a maximum temperature of 105°C.
BitFenix Whisper use solid Capacitors to reduce up to 35% of ripple & noise to the motherboard that result in solid performance and high overclocking stability.
With availability of dual CPU 4+4pin cables on 750W and 850W, BitFenix Whisper not only supports mainstream systems, but also extreme over-clocking motherboards, dual CPU setups, Industrial servers and workstations
LLC resonant topology brings lower power losses and boosts higher efficiency during AC-DC voltage switching. This maintains the stability of the output while reducing the energy wasted, mainly as heat, thus reducing the overall temperature of the PSU
BitFenix Whisper power supplies come with numerous protection mechanisms to protect both the power supply as well as components from poor power delivery
BitFenix Whisper together with all the above premium features is covered by 7 years of warranty and BitFenix Online Support is available to answer any questions or concerns regarding all BitFenix Products
