750W 80 PLUS Gold Full Modular Power Supply

The BitFenix Whisper M 750W 80+ Gold Fully Modular Power Supply sets a new standard for silent, efficient, and high-quality PC power delivery. Designed with the perfect balance of performance and reliability, it caters to gamers, creators, and professionals who demand stable power and whisper-quiet operation. With its advanced circuitry, top-tier Japanese capacitors, and intelligent cooling system, the Whisper M delivers exceptional energy efficiency and durability for modern computing environments.

High Efficiency Layout for Silent and Stable Performance:

The BitFenix Whisper M is built on a high-efficiency layout that maximizes performance while minimizing heat and noise. With 80+ Gold certification, it achieves up to 92% efficiency under typical loads, reducing wasted energy and improving system stability. This efficient design ensures cooler operation and lower fan speeds, enabling the PSU to maintain near-silent performance even under heavy loads. The result is a perfect balance between power, efficiency, and acoustic comfort.

Intelligent Fan Curve for Optimal Cooling:

Thanks to its Intelligent Fan Control Curve, the Whisper M dynamically adjusts fan speed based on temperature and load conditions. The PSU remains virtually silent up to 60% load, even during demanding operations such as gaming or rendering. This smart design minimizes noise without compromising cooling efficiency, ensuring a smooth and quiet computing experience for both enthusiasts and professionals.

Industrial-Grade 140mm FDB Fan for Superior Cooling:

Unlike standard PSUs, the BitFenix Whisper M is equipped with a 140mm Fluid Dynamic Bearing (FDB) fan that starts operating at just 3.5V. This enables the fan to spin at extremely low speeds — as low as 500 RPM ±10% — resulting in ultra-quiet operation under light loads. With noise levels under 18dBA, dust-resistant construction, and a long lifespan, the fan provides reliable cooling and durability for years of continuous use.

Exceptional Power Efficiency and Environmental Friendliness:

The Whisper M is designed to be environmentally responsible, generating up to 80% less heat and consuming 30% less power than standard PSUs. It supports Intel C6/C7 low-power sleep states and utilizes LLC, Active PFC, and DC-to-DC conversion circuits, ensuring energy efficiency while maintaining voltage stability. This eco-friendly design reduces your carbon footprint while delivering top-tier power performance.

Dedicated Quad Rails for Maximum Stability:

BitFenix Whisper M features a dedicated quad-rail design, ensuring independent power delivery to critical components like the motherboard, CPU, and GPUs. Each rail is protected by Over Current Protection (OCP), safeguarding high-end components from power surges. This intelligent power distribution guarantees exceptional voltage stability, making it ideal for gaming rigs, workstations, and multi-GPU setups.

DC-to-DC Conversion for Smooth and Reliable Power Output:

By integrating a DC-to-DC conversion circuit, the Whisper M delivers cleaner and more stable voltages across the +3.3V and +5V rails. This advanced design improves system stability, enhances component longevity, and ensures consistent performance under fluctuating loads. It’s a key factor in maintaining reliable and efficient power delivery for today’s complex PC architectures.

Maximum Power Delivery on 12V Rails:

The Whisper M 750W is optimized for full power delivery on the +12V rails, supporting even the most power-hungry GPUs and CPUs. With smart load balancing and dynamic power allocation, it ensures consistent output and reliable performance across all rails. Whether you’re gaming, editing, or overclocking, your components will always receive the power they need without compromise.

High-Performance Cables for Enhanced Power Delivery:

BitFenix includes 18AWG thick DC cables with embedded electronic components that stabilize voltage and reduce ripple. These specially designed cables improve overclocking potential, boost durability, and ensure reliable power delivery to all components. With extended 650mm PCIe and CPU cables, the Whisper M easily fits into larger chassis while maintaining tidy cable routing.

Japanese Industrial Capacitors for Longevity and Precision:

The Whisper M uses 100% Japanese industrial-grade capacitors, rated to withstand temperatures up to 105°C. These high-quality components ensure tight ±2% voltage regulation, superior reliability, and extended lifespan. This industrial-grade build quality makes the Whisper M ideal for users who demand consistent power and long-term performance.

Solid Capacitors for Reduced Ripple and Enhanced Stability:

Complementing the Japanese capacitors, the BitFenix Whisper M incorporates solid capacitors to further minimize voltage ripple and noise by up to 35%. This contributes to smoother power delivery, enhanced motherboard stability, and improved overclocking results, ensuring your system runs efficiently under any workload.

Ready for Industrial Servers and Dual CPU Systems:

With dual 4+4-pin CPU connectors, the Whisper M 750W supports not only gaming systems but also industrial workstations, dual-CPU setups, and high-performance servers. This versatile capability makes it suitable for professional environments that demand consistent power delivery and stability under continuous heavy workloads.

LLC Resonant Topology for Superior Power Conversion:

The LLC resonant topology ensures minimal power loss during AC-DC conversion, maximizing efficiency and maintaining stable voltage output. This advanced circuit design reduces wasted energy as heat, keeping temperatures low and extending the PSU’s lifespan while delivering steady power to critical components.

Comprehensive Protection for Ultimate Reliability:

BitFenix Whisper M provides complete protection with OCP, OVP, UVP, OPP, SCP, OTP, NLO, and SIP safeguards. These industrial-grade protection features ensure your components are shielded from electrical damage, guaranteeing reliable and safe operation for even the most demanding PC configurations.

In summary, the BitFenix Whisper M 750W 80+ Gold Power Supply is a masterpiece of silent engineering, efficiency, and reliability. From its intelligent fan system to its industrial-grade capacitors and modular design, it’s built to power high-performance systems with minimal noise and maximum stability — a true benchmark for premium PC power solutions.

User-Friendly Design:

To make the multi-rail system easier to use, the BitFenix Whisper PSU includes a clearly printed power distribution table right on the unit, allowing users to quickly see how much power each rail delivers. Each connection is also labeled with its corresponding rail, ensuring the correct cables are used to supply adequate power.

Modular Cables:

The BitFenix Whisper isn’t just about performance — it also offers a clean and refined design. It features a fully modular layout with flat, ribbon-style cables for easy management. The 18AWG output DC cables, including 650mm-long CPU and PCI-E 2.0 cables, are designed to fit comfortably in almost any PC case.
