Finally, with the latest version 11 of the Straight Power series, a power supply has been presented that is more than just a new revision with minor improvements in details. be quiet! has launched a product again that has been significantly upgraded in terms of efficiency, layout and variety of connections - and is again whisper-quiet.
The features of the Straight Power 11 850W at a glance:
- Fully modular cable management
- New half bridge with LLC resonance converters for higher performance
- Four high-performance 12V cables
- 105-degree Celsius electrolytic capacitors and solid capacitors increase efficiency
- Ultra-quiet 135 mm Silent Wings 3 fan
- 80 PLUS Platinum certified
- Fully modular cable management
- Five-year manufacturer's guarantee
- Efficient top-class power supply
The Straight Power series previously stood for high quality. It forms the broad middle class of be quiet! and is offered in many performance levels as well as with and without cable management. This means that a suitable model is available for almost every requirement. All fall back on a common PSU housing, which also plays a special role optically with its anthracite paint and unusual fan grill.
In-house 135 mm fans from the Silent Wings 3 series are used in all power levels of the Straight Power 11, which are also decoupled by a further developed frame design. Decoupling and lower speed with a large fan diameter mean that the Straight Power 11 Series work even more quietly than its predecessors. With this model, a maximum of 22 dB (A) is already a house number and practically inaudible for an average ear from the housing.
Increased performance thanks to high-quality components
When it comes to efficiency, the Straight Power 11 series can also be used and is still certified according to 80 PLUS Platinum. The power supply offers a fantastic efficiency of up to 94 percent (!) - so far, not many manufacturers have managed to do this, especially not in the mid-range segment. The stand-by consumption has been reduced again and is usually around 0.12 watts. Thus, the Straight Power PSUs are not only top-notch in terms of performance, but also in terms of preserving the environment and the household budget.
The Straight Power 11 owes these outstanding values to the exclusive use of high-quality Japanese 105-degree Celsius electrolytic capacitors and solid capacitors. In addition, new half bridges with LLC resonance converters are now being used. The completely modular cable management ensures better ventilation of the power supply and therefore also a longer service life.
The power supply has four independent 12-volt lines, which provide a combined 70.8 amps and 849.6 watts. A 20 + 4-pin ATX and, an 8-pin EPS12V and a 4 + 4-pin ATX12V cable supply the mainboard with energy. Four 6 + 2-pin PCIe connectors are available for the graphics card (s) and eleven SATA and four Molex connectors supply the periphery.
