Be Quiet! has again launched a product on the market that has been significantly enhanced in terms of efficiency, layout and connectivity - and that once again runs whisper-quiet.
The Features of the Straight Power 11 Straight Power 11 850W at a Glance:
Fully modular cable management
New half-bridges with LLC resonance transducers for higher performance
Higher efficiency thanks to 105-degree Celsius electrolytic capacitors and solid capacitors
50 Watts more performance
Ultra-quiet 135 mm SilentWings 3 fans
80 Plus Gold certified
Superb Power Supply with Incredible Efficiency
The Straight Power series stands as always for high quality. They represent the broad middle-class of Be Quiet's! range and are available in a range of performance levels as will as with and without cable management. This means there is the right model for almost any challenge. All of them use a common PSU casing that comes with an impressive anthracite look and unusual fan grids that make it very visually appealing.
All performance versions of the Straight Power 11 are equipped with 135 mm fans from the Silent Wings 3 range, and these additionally come with an advanced frame design. De-coupling and lower fan speeds together move plenty of hair while ensuring the Straight Power 11 series functions at even lower noise levels than its predecessors. This model produces a maximum 25 dB(A) which for the average ear is virtually inaudible once installed.
Performance Increases Thanks to Premium Components
When it comes to efficiency the Straight Power 11 series leaves no stone unturned and comes with 80 Plus Gold certification. These means the power supply is up to 93 percent effective (!) - something which not many manufacturers achieve, at least not in the mid-range segment. Stand-by power usage has been decreased once again and amounts to around 0,12 Watts. Not only are the Straight Power PSUs fantastic in performance terms, but also in terms of their impact on the environment.
The great specs on offer with the Straight Power 11, along with many other positives, are thanks in no small part to the use of Japanese 105-degree Celsius electrolytic capacitors and solid capacitors. Additionally, new half-bridges with LLC resonance transducers are used. The fully modular cable management provides improved airflow for the power supply and, as a result, an increased lifespan. These improvements allowed Be Quiet! to increase performance by 50 Watts and even offer this version with a full 850 Watts.
The 850 Watt represents a leading model in the series. Correspondingly it comes with four independent 12 V rails which combine to offer 70,8 Amps and 849,6 Watts. This is supplied to the motherboard by means of a 20+4-pin ATX connector, a 4+4-pin- and an 8-pin EPS cable. The graphics card(s) can be powered via four 6+2-pin PCIe connectors and eleven SATA- along with four Molex connectors power the peripherals.
