Evaluating the effectiveness of modern computer power supplies, the most attention is paid to their coefficient of performance (COP) at a given load — usually means of 20%, 50% and 100%. At the same time, not less important requirement, established by standard 80PLUS should be considered. That means — the preservation of this level of performance for all occurring in the world supply voltage variations, that is in the range of 100-240 V.



The standard rules of 80PLUS at different levels (Basic, Bronze, Silver, Gold, Platinum, etc.) are performed for two voltage 115 V and 230 V. In both cases, the normalized PS should show the efficiency of not less than specified for each category level. Not usual power supply CTG-650C model of the new A-80 series from the Chieftec company is interesting in that it has officially claimed efficiency of 85% or more, but only for nets 220-240 V.


As the advantages of such solution can immediately be noted a lower price, due to less stringent …

AMD has won a reputation not only for designing and supplying high-end processors but also for introducing its brand memory expansion, codenamed AMD Memory Profile. This development is called to store and share memory settings profiles and to facilitate the search for the most rational settings. Thus, ECS company is going to implement AMP support for DDR3 memory into its future and current lineup of motherboards. According to the available data, AMP technology will be applied to the upcoming motherboards with AMD processors, and to the current products by means of UEFI firmware update. This is the first 'revival' of the technology since its reconsideration and upgrade.



The integrated technology is destined to setup new frequency, voltage and timings showings which will facilitate in keeping DDR3 memory modules stable. As a rule, random-access memory with high frequencies of more than 2GHz require manual system overclocking. AMP will prevent the emergence of errors while setting …

With development of modern technologies, one may say that flash drive DataTraveler Locker + G2 represented by Kingston Digital has something common with antiques. According to the manufacturer «Flash Drive» is equipped with an interface USB 2.0, in recording mode has speed of 5 MB / s. Maximum speed in reading mode is equal to 10 MB / s.



Not surprisingly, that by promoting a new product the company relies on another feature — data protection. According to Kingston Digital, one can be confident in the safety of important data with DataTraveler Locker + G2. The drive automatically protects all information in two ways — using a hardware encryption and password protection. The drive has a password manager for the secure storage of user names and passwords (up to twenty accounts), as well as access to them. After ten failed attempts to enter the password, «flash drive» is locked and formats itself.


Drive DataTraveler Locker + G2 is compatible with Mac OS X and Windows, …
