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 …

Fractal Design Showcases an Offbeat Define S Chassis

Fractal Design, a well-known Swedish PC hardware developer, comes out with an innovative PC chassis, entitled Define S. The new-comer offers an ideal balance of functionality with a perfect soundproofing. Its exterior is differentiated by a classic strictness and style combined with a totally black coverage. The case might accommodate as mini-ITX/mATX motherboards, so full ATX items. Moreover, potential customers are able to choose between a windowed version ($90) and an entirely blind version ($80) of the chassis.

Key peculiarity of Fractal Design Define S model is absence of traditional bays for ODD and HDD/SSD. Instead of them, there are dedicated vertical seats on the reverse side of the motherboard tray for three 3.5-inch drives and two additional 2.5-inch drives. Seats for the 5.25-inch ODD are absent at all.

The layout allows for the installation of 425-mm graphics cards (if frontal fans are excluded, the maximal admissible length of cards might be 450 mm), CPU …

Meeting Ballistix Elite DDR4 Memory from Micron Technology

As part of Crucial brand, Micron Technology comes out with a new generation of RAM – the Ballistix Elite DDR4. It is developed in a pure black PCB with a powerful heatspreader and an integrated thermal sensor. Initially, the company releases planks of 4 GB and 8 GB, although in retail sale the products will be available in 8 GB, 16 GB, and 32 GB kits. Pricing is unknown so far.

Crucial Ballistix Elite DDR4 memory operates at 2666 MHz frequency and boasts 21 Gb/sec throughput index. Its power-efficient facilities are 40% better than those inherent in DDR3 models with analogous clock frequency. This makes gaming process a delight due to intense responsiveness, optimized latencies, and increased frame rates.

The modules support XMP 2.0 profiles as well as Ballistix Memory Overview Display utilities; the latter track the performance of each module, analyzing temperature, voltage and frequency showings in real time. Furthermore, Micron Technology makes its DDR4 compatible …
