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 …

Meet the 2nd Generation of Maximus 2 Platform from Nvidia

Last November Nvidia 'shattered' the IT market with its Maximus platform. Currently, the company is officially presenting the second generation of the platform – Maximus 2. The new platform is based on the advanced GPUs which employ Kepler architecture. The major task assigned to the Maximus 2 is to provide an unmatched performance and efficiency in quite different spheres of enterprise, starting from computer graphics and finishing with oil industry. Besides, it has got improved facilities of virtualization and analyzing activities.

According to the data claimed by the manufacturer, workstations developed on Maximus 2 platform will be put into sale already this December. It is already known that there are a number of companies that will employ Nvidia Maximus 2 in their product lines. Hence, such companies as Dell, HP, Lenovo, Supermicro, and BOXX technologies will introduce their workstations based on this platform.

It should be stated that the second generation of …

ASRock FM2A88M-HD+ to Support the Latest AMD Kaveri APUs

ASRock has recently announced a new series of motherboards that are based on the prime-class AMD A88X chipset, targeting Socket FM2(+) CPUs of Trinity and Richland generation. Moreover, they are supposed to support the new-gen AMD Kaveri APUs with Steamroller microarchitecture. One of the most outstanding models within the series is FM2A88M-HD+ motherboard, which features a large amount of slots and sockets. At the same time, it remains a cost-efficient solution.

ASRock FM2A88M-HD+ is designed in a micro-ATX form-factor, featuring 234x183 mm dimensions. The company claims that this model is able to accommodate DDR3 RAM with 2133 MHz frequency, housed in two DIMM slots. Therein, the maximal memory capacity might achieve 32 GB. Hardware base consists of prime-quality solid-state capacitors and durable chokes. Three expansion slots are introduced by one PCI, one PCIe 2.0 x1, and one high-speed PCIe 3.0 x16; the latter demonstrates up to 15.75 Mb/sec bandwidth.
