Greeting Deepcool Wave Mini-Tower Case

Deepcool Industries Co. Ltd., a renowned Chinese developer of PC cooling solutions, is about to launch another top-notch chassis, codenamed Wave. This mini-tower model, featuring 387x175x353.5 mm dimensions, is supposed to accommodate micro-ATX systems. Despite a sleek design and enhanced functionality, entry-level customers will be able to acquire the new-comer for some $30-40.

Deepcool Wave is housed in a steel chassis (0.5 mm SECC) with plastic details. Its internal layout is predestined for two 5.25-inch drives, a triple of 3.5-inch drives and the same number of 2.5-inch drives. Expansion facilities are ensured by means of four PCI slots. There is enough space for the installation of 145-mm-high CPU cooler, 320-mm-long graphics cards, and ATX-compatible power supply unit.

The chassis comes with a single preinstalled 120 mm frontal fan, equipped with blue LED backlight. There is a possibility to boost air cooling by integrating two more fans. Connectivity is secured …

Greeting Small-Sized HIS R9 270 iCooler Boost Clock 2GB GDDR5 Graphics Card

The middle-end lineup of HIS’ proprietary graphics cards has been refilled with a new small-sized model: the R9 270 iCooler Boost Clock 2GB GDDR5. It features 190x125x45 mm dimensions and maintains an etalon clock frequency template. Hence, its price won’t differ too much from the recommended one. The new-comer boasts a bright design with a blue PCB and light-blue fan blades. Despite the appurtenance to the middle-end segment, the card is able to demonstrate quite an appropriate performance.

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 …
