PSU Enermax Revolution87+ 750W Review

This year has become rather successful for Enermax, a well-known manufacturer of power supply units. The company supplemented its product lines with six series combined into four major groups: entry-level, athlete, royal, and gold class. Revolution87+ series belongs to the Gold Class group and involves five models (from 550W to 1000W power). Model Revolution87+ 750W is distinguished not only by the availability of 80Plus Gold certificate, but also by an original branded platform developed by Enermax specifically for this series.



Features


Enermax has implemented a few striking technical solutions in its Revolution87+ 750W power supply unit. The first attractive feature is a composite control over the main inverter. The control is realized by traditional pulse-width modulation method, as well as by simultaneous involvement of pulse-frequency modulation (the combination of width and frequency in control process).


Upon the whole, this PSU model is able to demonstrate up …

HIS submitted a non-reference card Radeon HD 7970 X

Hightech Information System Company has completed the development of its secret weapon — the video card HIS 7970 X. The relatively modest-looking product, according to producer’s statement, is equipped with a (18 +1 +1)-channel power supply system, high-performance cooler IceQ X2 and non-standard set of ports — four Mini DisplayPort, single DVI and HDMI. The technology AMD Eyefinity 6 is supported — simultaneous work with six monitors. Clock frequency speeds up model 1000/6000 MHz for core and memory respectively. Hong Kong vendor assigns a novelty to a class of graphics cards Radeon HD 7970 GHz Edition.



The cooler is composed by a copper base, three 6-mm and two 8-mm heat pipes, ribs (cooler chips on the VRM and RAM), an aluminum radiator. A pair of 90-mm fan cool the core of Tahiti XT (2048 shaders, 384-bit memory bus) which combines with 3072 MB of memory GDDR5. Additional power is provided by two 8-pin connectors PCI-E Power, in addition memory individually powered …

A Pair of New Graphics Cards Radeon HD 7950 Boost Edition from MSI

MSI has replenished its series of Radeon HD 7950 graphics cards with a pair of new Boost Edition models. Codenamed R7950-3GD5 BE and R7950-3GD5/OC BE, both adapters feature practically identical to the first two releases (of the very series) design. Nonetheless, the novels are known to support AMD ZeroCore with Boost technology that provides for an automatic GPU clock frequency boost on conditions of an increased computing loading. Dynamic clock frequency indices of both models are not so dramatic, since they exceed the nominal showings at 10 MHz only; still, the support of a brand MSI Afterburner utility enables a raise of frequencies to the required level.



The two representatives of MSI Radeon HD 7950 Boost Edition series employ GDDR5 memory with an overall capacity of 3 GB and 384-bit interface. Its nominal clock frequency equals to 1250 MHz, while its efficient frequency achieves 5000 MHz. Memory modules, as well other critical components, are cooled down by a two-slot …
