Modular Power Supply 650W Chieftec A80

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 …

Silicon Power Unveils Armor A85M External Storage

Silicon Power Computer & Communications is about to kick off with the newest stress-proof external drive, entitled Armor A85M. The model, targeting Mac users, features 132.5x92.3x25.9 mm dimensions and completely complies with MIL-STD 810G Method 516.6 Procedure IV standard. It also enjoys IP68 protection rating. The new-comer will be shipped with a 3-year’s warranty; however, pricing is unknown yet.

The storage is thought to operate within a wide thermal range – from 5 to 55 C degrees. Moreover, it might be employed in tough conditions, i.e. submergence, fall from a height of 1.2 m, storing in extreme colds/heat (-40 C degrees — +70 C degrees).

SP Armor A85M will be available in three capacities: 500 GB, 1 TB and 2 TB. All of them are equipped with USB 3.0 interface with 5 Gb/sec bandwidth. The implemented USB port serves not only data transfer functions; it’s also a power cord. The case accommodates power and processing LED indicator.

Intel Claims Its Clover Trail More Efficient than Tegra 3

The stonewall in the tablet and mobile CPU segment is gradually mounting, with Intel and Nvidia increasing their influence and rivalry. Hence, Intel's developers claim that its latest tablet processor, two-core Atom Clover Trail, surpasses Nvidia's Tegra 3 in both performance and power consumption. To be precise, Clover Trail proves to be more efficient in a range of applications, but at the same time, it consumes power twice less than its counterpart. To exemplify such claims, Intel takes Imagination Technologies graphics that consumes less power than Tegra 3.

Numerous testing results conducted by Intel and some leading IT analysts demonstrate that Tegra 3 with four main cores and one additional core is slower that Clover Trail. Testing of performance and power consumption has been held on Microsoft Surface RT with Tegra 3 chip and Windows 8 tablet with Clover Trail chip. Nevertheless, Intel hasn't conducted any comparison in mobile OS from Google.
