Power supplies Dark Power 12

08.03.2021

The range of power supplies from the German company be quiet! has replenished with a line of Dark Power 12 devices. This series has occupied a niche for Dark Power Pro 12 and is represented by models with a nominal value of 750, 850 and 1000 W. All boast 80 Plus Titanium energy efficiency certification (up to 96% efficiency on 230V), a 10-year manufacturer's warranty and a modular cable management system.

The maximum load on 12-volt lines is from 744 W (62 A) to 996 W (83 A) depending on the rating of the power supply. It is worth noting the presence of the Overclocking Key switch, which allows you to combine four "virtual" +12 V lines into one heavy-duty channel, which will interest fans of sports overclocking.

A 12 mm Silent Wings 135 fan with a frameless design is responsible for cooling the "stuffing" of the Dark Power Pro 3 blocks. The noise level of the older model, according to the manufacturer, does not exceed 25,8 dBA. There are protection systems against high and low voltage, overcurrent and power, short circuit and overheating.

Power supplies from be quiet! The Dark Power 12 will arrive on March 9th with prices starting at $200, $240 and $280 for the 750W, 850W and 1000W versions, respectively.

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of ​​controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog ​​owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

Recyclable printed circuit boards 03.05.2024

Electronics play a key role in today's world, but the accompanying rise in e-waste is putting the environment at risk. In response to this problem, researchers at the University of Washington have developed an innovative technology that could change conventional wisdom about circuit board recycling. A team led by scientists from the University of Washington has created a vitrimer printed circuit board that has the unique ability to be recycled multiple times. Using advanced environmentally friendly polymers, the researchers developed a material that can be turned into a jelly-like substance using a special solvent. This opens the way for PCBs to be reused and recycled without significant loss of quality. Vitrimer printed circuit boards (vPCBs) represent significant advances in environmental sustainability. Unlike conventional plastics, which are susceptible to degradation during repeated recycling, jelly-like vitrimer retains its ... >>

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

White graphene for microcircuit cooling 26.07.2015

Rice University scientists studied the properties of a columnar allotropic variety of boron nitride (BN), which is called "white graphene" due to its isoelectronicity with carbon and the ability to form layers one atom thick, and concluded that this material has a higher thermal conductivity than the structures that form it. separately.

Modeling the parameters of a material in which the layers are connected by nanotube columns showed that its thermal conductivity depends on the distance between the columns and their length.

The study may be promising for solving the problem of microchip cooling.
