HIS Adds a Couple of Middle-Yielding Graphics Cards to Its Inventory

The inventory of HIS production line has been refilled with a couple of new graphics cards that belong to middle-yielding solutions. The couple enters HIS 7770 IceQ X Blue series and is targeting those users who would like to enjoy all the privileges of gaming process for a sensible price. Codenamed HIS 7770 IceQ X Blue and 7770 Ice Q X Blue Turbo, these entries are able to provide for an outstanding viewing effect, while playing the most up-dated games.

The heart of both graphics adapters is AMD Cape Verde TX core with 640 current processors, developed under 28 nm Graphics Core Next architecture. Model HIS 7770 IceQ X Blue runs at reference clock frequency of 1000 MHz, while its Turbo colleague is factory-overclocked and runs at 1100 MHz frequency. In respect to video memory, this couple accommodates 128-bit GDDR5 modules. Their nominal clock frequencies make up 1125 MHz and 1200 MHz (for Turbo model), while their effective frequency index achieves 4500 MHz and 4800 MHz …

NEC Replenishes Its MultiSync Series with MD242C2 Monitor

NEC has replenished its product line with a new 24-inch monitor that joins MultiSync series. Codenamed MD242C2, the model is housed in a case of a rather strict design, featuring 556.8x227.6x378-528 mm dimensions. Upon the whole, this monitor positions itself as the most appropriate solution for medical establishments, providing for an accurate imaging.

Monitor NEC MD242C2 is based on IPS array with LED backlit and 12 ms response time (8 ms in Gray-to-Gray mode). Its operational resolution equals to 1920x1200 pixels, while the display aspect ratio makes up 16:10. Viewing angles, both vertical and horizontal, equal to 178 degrees, brightness achieves 350 cd/m2 and static contrast is estimated as 1000:1. NEC employs 14-bit look-up tables (LUT) to ensure proper color output and more accurate display of gray hues in blackened areas.

To continue, the manufacturer equips this model with mini D-Sub, HDMI, DVI-D, and DisplayPort video outputs. The two latter ports are known to …

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 …
