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 Formula Gold power supply line up comes with a wide range of power options starting with 450W all the way up to 750W incrementing by 100W.


  • High Efficiency Layout

    As the name suggests, Formula is an extremely high efficiency power supply with an 80+ Gold Efficiency certification. Because of the 2oz pure copper double layer PCB and use of high quality components, the PSU series keeps the best formula of high efficiency and capable of functioning with a very low noise and heat level while providing stable voltage output at highest loads.
  • Intelligent Fan-Curve

    Thanks to the use of an Intelligent Fan Control Curve the fan speed is smartly controlled to minimize the noise levels while maintaining optimum temperatures as its big brother BitFenix Whisper M. Formula can operate at room temperature with minimum noise even at 60% load, meaning that the noise level is dead silent even carrying out intensive work loads.

  • Industrial Quality Fan

    Unlike regular PSUs, Formula Gold comes with a 120mm FDB fan that starts working at a much lower voltage of 3.2V 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 Formula Gold can operate at noise levels lower than 18dBA while PSU load is lower than 60% at 25°C.

  • 550W




  • 650W




  • 750W








  • Ultra Efficient

    Formula Gold 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 60% load) high efficiency design, Formula Gold saves both energy and money for the user while providing extremely stable power output at a very low noise level.

  • Environmental Friendly

    Generate up to 80% less heat and consume 30% less power than standard PSU’s. BitFenix Formula Gold 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 Formula Gold Power Supply saves energy and your environment while providing unmatched power quality for your computer hardware.



  • Dedicated Multi +12V Rail

    As BitFenix Whisper M, a dedicated multi-rail design together with an advance voltage switching circuit from +12V to minor rail provides the best stability and output quality. The main multiple +12V rails on all BitFenix Formula Gold models are dedicated as Motherboard + Peripherals, CPU, VGA1 and VGA2 (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.



  • DC-to-DC Circuit

    Due to the use of a separate DC-to-DC circuit to convert +12V to +5V and +3.3V, the output voltage regulation from Formula Gold is much more stable and smooth. This increases the system stability as well as the durability of components.

  • Maximum Power on +12V Rails

    Formula Gold 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, Formula Gold have a higher current capacity on VGA 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.

  • Compact Design

    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


  • Up to 650mm Fixed Flat cable

    Performance is not the only focus of BitFenix Formula Gold, built to a simplistic yet elegant design BitFenix Formula Gold uses fixed with flat ribbon-style cables. These cables are up to 16AWG thick output DC cables to provide high efficiency and tightest voltage regulation.


  • High Performance Cables

    The special designed flat ribbon-style cable and feature electronic components to stabilize the power delivered to the components increasing the duability as well as overclocking potential of the components. This feature reduces the power drop caused by unknowing interference noise around system environment and makes sure the components get enough power to operate at optimum levels.

  • 100% Industrial Japanese Capacitors

    BitFenix Formula Gold 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 Formula Gold can function at a maximum temperature of 105°C.



  • Solid Capacitors

    BitFenix Formula Gold uses solid capacitors to reduce up to 35% of ripple & noise to the motherboard that result in solid performance and high overclocking stability.


  • Support up to Industrial workstation

    With availability of dual 4+4pin cables on 650W & 750W, BitFenix Formula Gold not only supports mainstream systems, but also extreme overclocking motherboards and workstations.



  • LLC Resonant Topology

    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.
  • Industrial Level Protection

    BitFenix Formula Gold power supplies come with numerous protection mechanisms to protect both the power supply as well as components from poor power delivery.
    •Over Current Protection (OCP)
    •Over Voltage Protection (OVP)
    •Under Voltage Protection (UVP)
    •Over Power Protection (OPP)
    •Short Circuit Protection (SCP)
    •Over Temperature Protection (OTP)
    •No Load Operation (NLO)
    •Surge & Inrush Protection (SIP)



  • 5-Year Warranty

    BitFenix Formula Gold together with all the above premium features is covered by 5 years of warranty and BitFenix Online Support is available to answer any questions or concerns regarding all BitFenix products.
