An exclusive Hi-End class power supply with a rated power of 750 W, which, by the way, is not the limit for this device — the OverLOAD option allows you to increase the peak load, without output voltage drop, up to 875 W! The PSU is certified according to the 80 PLUS GOLD standard, so this model can be trusted to power powerful and expensive components. The efficiency reaches 93%. The model received 4 independent power lines (12 V), which makes it as reliable as possible. The Be quiet Straight Power 11 Straight Power 11 750W power supply utilizes a fully modular wire connection, allowing you to make the most of modern cable management solutions for advanced system units. One of the main features is the use of boards with a wireless connection of components — the absence of unnecessary wiri...ng has a positive effect on cooling. The circuitry is built using Japanese-made capacitors, which are distinguished by excellent stability and reliability even when operating at a temperature of +105 ˚С. Active cooling is provided by a 135mm fan that is supported by a high quality fluid dynamic bearing. The operation of the fan will not disturb the silence and harmony.

Can you be quieter?

By creating the Be quiet brand, the German company Listan GmbH decided to occupy an interesting niche of elite and almost silent power supplies. With a combination of premium circuitry and acoustic comfort, their products are equally in demand among gamers-enthusiasts and pros working with audio and video content. So the Straight Power 11 model became a hit for a reason, because it is one of the quietest computer power supplies with an 80+ Gold certificate and a power reserve of 750 watts. Its proprietary 14 cm Silent Wings 3 fan with hydrodynamic bearing barely emits 9 dB of noise that is indistinguishable to the ear at idle, and at peak load it starts to barely noticeably rustle (less than 21 dB).

Japanese capacitors and maximum protection

The advantages of this model also include high stability of output voltages, the presence of all types of protection and a completely changed circuitry compared to Straight Power 10. If earlier Taiwanese capacitors were used, then this time we see durable Japanese Nippon and Rubycon capacitors. An interesting feature was the division of the main 12-volt line into four sub-lines: the first feeds the motherboard and peripherals (disks, fans), the second processor, the third and fourth — video cards. On the one hand, this made it possible to achieve better voltage stabilization, on the other hand, it will not allow installing a couple of very “gluttonous” video cards into the system.

This is Love

On other fronts, Straight Power 11 also claims a medal and declarations of love: it has a fully modular structure, all cables are braided and with such a margin of length that it is enough for any case, there are four 6 + 2-pin connectors for video cards and a whole pack SATA and Molex connectors for connecting any peripherals. Well, the five-year warranty sets in a positive way. Of course, the price for this stuff will be higher than for 750-watt models from the conditional Chieftec, but it seems to us that talking about overpayment is not appropriate here. Still, this is a slightly different level, and the quality of Straight Power 11 speaks for itself.
