Sapphire Showcases Radeon HD 7870 GHz Edition Toxic Solution

Sapphire Technology Ltd. is going to release a new graphics card on Tahiti LE chip. Codenamed Radeon HD 7870 GHz Edition Toxic, the card is one of the first models to use the newest GPU, developed under 28 nm technological process. The suffix 'GHz Edition' in the model's name witnesses that the nominal GPU clock frequency exceeds the index of 1 GHz.



The core of Sapphire Radeon HD 7870 GHz Edition Toxic is based on Graphics Core Next architecture and contains 1536 current processors. The card's inventory involves 2GB of GDDR5 memory with 256-bit bus interface. The memory modules are known to operate at 6000 MHz frequency. GPU operational frequencies are still not clarified, but it's possible to assume that on activation of AMD PowerTune option the card will demonstrate some outstanding performance. In fact, analysts dare saying that this model is the most efficient one among all other solutions based on Tahiti LE chip.

ID-Cooling Hunter Duet II Liquid Cooling System

ID-Cooling, being famous for its cooling systems, has released a Hunter Duet II cooler of large dimensions, which is supposed to transfer heat from the CPU and the graphics engine surfaces. This model is designed with a 360 mm heat sink, which is of great benefit to its efficiency factor.



The construction includes two water units with a base out of copper and built-in pumps, pipes in braided cable, the three-section aluminum 395 × 120 × 27 mm heat sink, three 120 mm fans, and an extraordinary framework with a 90 mm fan to blow over graphics card load-bearing elements and intensive plates for the CPU and GPU.


Though possessing similar construction, water units differ in lids design and the location of holes for liquid flow. At the moment their inner structure details are not available.

A compact fan to blow over VRM consumes 1.2 W. Its rotary speed is not higher than 1,500 rpm. The same ratio of each of the three main fans is not supposed to exceed 1,500–2,000 rpm.

Power Supply Unit FSP Aurum AU-1200 Pro Review

Present-day power supply units are the devices which combine the advanced technologies with eco-friendly approach. Their major destination is to provide the PC nodes with direct current electric power, however, PSU can realize additional stabilizing and protective functions. Aurum AU-1200 Pro belongs to the units of FSP series and offers an ideal combination of quality, efficiency and security. This PSU is based on MIAIC technology which ensures high performance characteristics and good level of PC protection.



Design and Integration


Unlike the traditional PSU design concept, FSP Aurum AU-1200 Pro is developed with a note of uniqueness. Its black casing creates an illusion of unflinching reliability, while the golden bordering of ventilation array adds some refinement to the unit. Aurum AU-1200 Pro is rather compact as compared to other units available in the market. It should be mentioned that developers succeeded in their attempts to achieve the maximal air outflow due to …
