Still waters run deep

Speaking of silent power supplies, you can’t ignore the products of the German brand Be quiet. In terms of acoustic comfort, these guys are the best of the best, which is confirmed by their flagship model Dark Power Pro 11 at 650 W, which rarely exceeds 15 dB even under serious load. And up to the mark of 300 watts, it generally works almost silently. This result was achieved by using the Silent Wings proprietary cooler with a special aerodynamic impeller and an improved hydrodynamic bearing. Perfect for demanding applications that still require quiet operation. If this is not enough, you can connect up to 4 additional coolers to the block, which will be synchronized with the main one.

Platinum Status

But further more, after all, the model is indecently expensive and is clearly designed for enthusiasts with a tight wallet and increased requirements for energy supply. So, the model is built on the basis of a platform from FSP, well known to overclockers, with top-end circuitry capable of delivering peak power 13% more than the nominal value, and an impressive efficiency of 94% (certified 80+ Platinum). The company's engineers place special emphasis on the fact that all this stuff can work 24/7 at an ambient temperature of 50 °C, that is, it meets the high requirements of server hardware. The +12V line also looks interesting, which can deliver all the power to one channel or distribute it to four “virtual” channels with current limits.

For enthusiasts with a tight wallet

In tests, Dark Power Pro 11 behaves exactly as you would expect from the king of the jungle: the voltage of the main lines is stable even under peak load, the ripple frequency is minimal, the work is stable and flawless. Therefore, it can no doubt be recommended for use in high-end systems with multiple graphics cards. Perhaps the only thing that can stop you from buying such a device is the high cost. But this is an uncompromising flagship with no weaknesses, so the price is justified. It is also one of the longest blocks in its category, be sure to consider this before buying.
