be quiet! Straight Power 11 BN282

Quiet Gold

be quiet! Straight Power 11 650W is one of the quietest computer power supplies with 80 PLUS Gold efficiency and 650W. Quieter than it are only solutions with popupassivny (hybrid) cooling, and even then they are silent only in idle time. Whereas the Straight Power 11 650W uses a proprietary 14 cm Silent Wings 3 fan with a fluid dynamic bearing, a six-winding motor, corrugated blades and a funnel-shaped frame. At idle, it emits 9 dB of noise that is generally indistinguishable by ear, at half load — 10 dB, and at maximum — still very quiet 17.5 dB.

No extra wires

The design of the Straight Power 11 650W PSU itself is completely modular, that is, all wires can be unfastened without exception. The cables are nylon-braided and very long: for example, the length of the traditionally most problematic 4 + 4-pin processor cable for neat laying is an enviable 70 cm. Four 6 + 2-pin graphics card power connectors are available.

German-Japanese quality

The Straight Power 11 650W circuitry, a creation of the German brand be quiet!, uses extremely durable Japanese Nippon and Rubycon capacitors. All possible levels of protection are implemented: OCP and OPP from overload, OVP and UVP from overvoltage and undervoltage, SCP from short circuit and OTP from overheating.

Four sub-lines

At the same time, the main 12-volt line is divided into four sub-lines for better voltage stabilization. The first feeds the motherboard and peripherals (disks, fans), the second — the processor, and the third and fourth — a pair of video cards. However such a scheme does not allow powering a couple of very energy-hungry video cards, like the Radeon Vega 64. For this task, it is better to choose a power supply unit with a solid +12 V line, such as be quiet! Power Zone 650W. Those wishing to save as much as possible on the purchase of a PSU, we recommend be quiet! Pure Power 11 500W.
