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 …

Gigabyte to Launch an Overclocked GTX 1080 Xtreme Gaming Videocard

Elegant design & astounding overclocking – that’s all about new GeForce GTX 1080 Xtreme Gaming videocard from Gigabyte. The model (codename: GV-N1080XTREME-8GD) is based on Nvidia’s GP104-400 GPU that is characterized by a high efficiency and a stunning performance. It can operate in OC or Gaming mode to better comply with users’ needs. In the former instance, the base/dynamic clock frequencies make up 1784/1936 MHz, whereas in the latter instance, this index equals to 1759/1898 MHz (reference showings: 1607/1733 MHz).

Gigabyte GeForce GTX 1080 Xtreme Gaming boasts the integration of 8 GB of GDDR5X video memory (256-bit interface) that has been overclocked to 10.211 MHz (Gaming mode) & 10.416 MHz (OC mode) respectively. The card is differentiated by an offbeat design with an X-style cover. The PCB comes equipped with LED backlight, supporting 16.8 million colors as well as a few running modes.

To continue, the greenhorn accommodates 12+2 VRM subsystem and Ultra …

Apacer Launches Memory Cards of SD and CF Format

Apacer Technology, world-known manufacturer of digital storage devices and memory cards, has introduced in a stately manner its latest ‘creations’, memory cards of SD and CF format, codenamed SD-M and CompactFlash5. The key feature of new products is the extended temperature range which allows the cards to show good operability under conditions of low temperatures (from -40 degrees centigrade) up to extremely high temperatures (to +85 degrees centigrade). The applied technology promoted for the expansion of these memory cards to a variety of areas, including aviation, military and automotive electronics.

According to the words of Apacer’s representatives, their memory cards are full-blown solid state drives with SD and CF interfaces. SD-M and CompactFlash5 are based on MLC NAND flash memory.

Memory cards with SD interface support SD 2.0 and Class 10 specifications, and will go in four volume capacity variants: 4, 8, 16, and 32 GB. Those cards are known to develop …
