EVGA GQ Series 80Plus Gold Power Supplies

11.11.2015

With an eye on demanding users, EVGA has developed a new series of power supplies GQ Series. The new products use support for EVGA ECO technology, which provides an almost silent fan operation, high-quality Japanese-made capacitors are used. The new power supplies are highly efficient and 80Plus Gold compliant.

The Whisper Silent feature only activates the 135mm fan when needed. At low to medium load, only passive components are sufficient for cooling, and at a higher load, active air cooling is included in the work. The efficiency of power supplies reaches 90% or more, depending on the load. The modular design allows you to connect only the cables you need.

All new models use a single +12 V architecture. For example, the 1000 W model provides a maximum load current of 83,3 A on its +12 V line. For the youngest model in the series (650 W), this figure is 54 A. All models support a full range of protection functions, including OVP (Over Voltage Protection), UVP (Under Voltage Protection), OPP (Over Power Protection), SCP (Short Circuit Protection), OCP (Over Current Protection), OTP ( overheat protection).
The series includes models with a power of 650, 750, 850 and 1000 watts.

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Implanted brain stimulator 30.04.2024

In recent years, scientific research in the field of neurotechnology has made enormous progress, opening new horizons for the treatment of various psychiatric and neurological disorders. One of the significant achievements was the creation of the smallest implanted brain stimulator, presented by a laboratory at Rice University. Called Digitally Programmable Over-brain Therapeutic (DOT), this innovative device promises to revolutionize treatments by providing more autonomy and accessibility to patients. The implant, developed in collaboration with Motif Neurotech and clinicians, introduces an innovative approach to brain stimulation. It is powered through an external transmitter using magnetoelectric power transfer, eliminating the need for wires and large batteries typical of existing technologies. This makes the procedure less invasive and provides more opportunities to improve patients' quality of life. In addition to its use in treatment, resist ... >>

The perception of time depends on what one is looking at 29.04.2024

Research in the field of the psychology of time continues to surprise us with its results. Recent discoveries by scientists from George Mason University (USA) turned out to be quite remarkable: they discovered that what we look at can greatly influence our sense of time. During the experiment, 52 participants took a series of tests, estimating the duration of viewing various images. The results were surprising: the size and detail of the images had a significant impact on the perception of time. Larger, less cluttered scenes created the illusion of time slowing down, while smaller, busier images gave the feeling of time speeding up. Researchers suggest that visual clutter or detail overload can make it difficult to perceive the world around us, which in turn can lead to faster perception of time. Thus, it was shown that our perception of time is closely related to what we look at. Larger and smaller ... >>

Graphene will improve HDD 24.06.2021

Scientists at the Cambridge Graphene Center have shown that graphene can be used to create ultra-high-density hard drives, providing a tenfold leap over current technology.

Hard drives, which have been widely used in personal computers since the mid-1980s, have become smaller in this time, but significantly more capacious. Although they are being squeezed out by SSDs, HDDs are still popular due to their lower cost.

The increase in volumes is due to the increase in recording density, which in turn is provided by the improvement of two key components: platters and heads. In particular, developments that made it possible to reduce the gap between them.

At present, a significant part of this gap is occupied by carbon-based coatings - layers designed to protect the plate from mechanical damage and corrosion. Since 1990, recording density has quadrupled and coating thickness has decreased from 12,5 nm to about 3 nm. These parameters correspond to a density of 1 terabyte per square inch.

The Cambridge researchers replaced current coatings with graphene (from one to four layers) and tested friction, wear, corrosion, thermal stability and lubricant compatibility. It turned out that, in addition to its unrivaled thinness, graphene has all the ideal properties of the external coating for hard drives in terms of corrosion protection, low friction, wear resistance, hardness, compatibility with lubricants and surface smoothness. It reduces friction by half and provides better protection against corrosion and wear than current solutions. In fact, one layer of graphene reduces corrosion by 2,5 times.

The team also tested locally heated media recording (HAMR), a new technology that can increase storage density. Unlike graphene, the coatings currently in use do not operate at the temperatures required for HAMR. As stated, graphene in combination with HAMR will increase the recording density to an unprecedented level - more than 10 terabytes per square inch.
