Performance and Efficiency
Both power supplies deliver excellent efficiency, with 80 Plus Gold certification ensuring minimal energy loss. The Be Quiet! Straight Power 11 emphasizes silent operation through its hybrid fan control, which adjusts fan speed based on load. The Corsair Rm750x’s zero RPM mode also reduces noise during low loads, making both units suitable for quiet environments.
In real-world testing in 2026, both units maintained stable voltages and handled high loads effectively. The Be Quiet! model’s fan remains quieter at higher loads due to its optimized design, while the Corsair’s zero RPM mode offers near-silent operation at low to moderate loads.
Build Quality and Design
Both power supplies feature high-quality components and durable construction. The Be Quiet! Straight Power 11’s fan uses a fluid dynamic bearing for longevity and quietness. The Corsair Rm750x employs a high-quality double-ball bearing fan, ensuring durability and quiet operation.
