Preview of video-card Club 3D Radeon HD 7970 royalAce

Club 3D has released fifth model of the Radeon HD 7970 — with the prefix royalAce in the codename. Before «ace» there were represented “the king” HD 7970 royalKing and “Queen” HD 7970 royalQueen. New model works at higher frequencies, and supports dynamic overclocking. Into the configuration of Club 3D Radeon HD 7970 royalAce inserted 2048 stream processors. Nominal of core is 1050 MHz in normal mode and 1100 MHz in 3D-games. GDDR5 memory chips make total of 3 GB and operating at 6 GHz, the memory bus is 384 bits.



Club 3D Radeon HD 7970 is notable by its effective use of a proprietary cooling system. It is equipped with a dual-slot cooling system royalAce consisting of at least three copper heat pipes, an array of aluminum fins and a pair of fan size 80 mm. According to the manufacturer reports, the construction is very quiet (31.5 dB in the normal mode of operation, 38 dB — under load), and secondly, provides a nice temperature (average during the game GPU …

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 …

Release of Chassis Aresze Subverter 7650B with Efficient Cooling System

Aresze is going to release its new series of chassis developed in Mid-Tower form factor. Codenamed Subverter 7650B, these chassis are primarily intended at consumers with the heightened demands to the layout and integration but with rather 'modest' financial possibilities. Subverter 7650B series can boast an outstanding efficiency pertained to cooling down. In addition, the internal zoning and integration of this model are similar to that implemented in more costly line of products manufactured by Aresze.



Aresze took all efforts to achieve the maximal results applied to the efficient cooling down. Thus, the framework zoning for the airflow distribution has been designed according to the company's own technology. The bay designated for graphics cards, which can support the cards of up to 300 mm in length, can be applied for the wide range of solutions. The 120 mm fan is located at the top part of the chassis and serve the blowing out means; this way the hot airflow does not …
