'Digital' PSU Corsair AX1200i Review

Power supply unit AX1200i designed by Corsair is a high-end product applied primarily in powerful desktop platforms. Its superior characteristics are currently widely spoken about, due to the promotion of the so-called 'digital' technology in PSU layout. 'Digital' PSUs employ digital signal processors instead of traditional analog controllers to provide for the utmost performance, efficiency, and facilities. Under Corsair's words, the implementation of digital options in the development of PC units, and particularly AX1200i model, is a justified measure viewed as from technological, so from economical prospect.

Basic Peculiarities

Corsair AX1200i is delivered in a large dual-base box, consisting of a paper cover and a corrugated cardboard. The box contains all basic information about the unit: +12VDC bus efficiency is estimated at 1204.8W/100A; the correlation between +12VDC bus and the overall power efficiency equals to 1.0 index that is supposed to be an excellent …

MSI Unveils New Gaming Graphics Card GeForce GTX 760 Hawk

MSI has recently introduced its newest graphics adapter with the support of Twin BIOS technology. Codenamed MSI GeForce GTX 760 Hawk, the card positions itself as an optimal solution for inveterate gamers, as well as for overclockers. The new-comer is based on Nvidia’s GK104 GPU (28 nm technological process) with 1152 CUDA cores. It runs on dynamically heightened frequencies, as compared with the reference model.

Therefore, the nominal clock frequency has been raised from 980 MHz to 1033 MHz, whereas the overclocked frequency has jumped from 1111 MHz to 1176 MHz. As for the memory, represented by 2 GB GDDR5 modules with 256-bit rail, its frequency index has not undergone any changes: 1502 MHz/6008 MHz (nominal/overclocked).

To continue, GTX 760 Hawk takes a fully modified 8-layer PCB as the basis. GPU power supply is ensured by means of an efficient power converter and prime-quality Military Class 4 components, including solid-state Hi-C CAP capacitors with tantalum …

Company XFX is preparing Radeon HD 7970 GE with Double Dissipation cooler

American vendor XFX is about two weeks to release a Radeon 7970 Edition Double Dissipation (model code — FX-797G-TDF). It combines the capabilities of GPU Tahiti XT2 with a higher overclocking potential and the TDP, rather than at Tahiti XT, PCB reference design, but without a single phase power supply (6 +1), and the cooling system in the vaporizing chamber, an array of aluminum fins, PA plate (the same heatsink for the VRM and memory), as well as the two fans standard size 90 mm.

New model will get the recommended for the Radeon HD 7970 GE frequency ratio 1000/6000 MHz for core and chips GDDR5. The graphics chip will operate at 1050 MHz in the load. Recall that the “usual” HD 7970 was limited to regular frequencies 925/5500 MHz and did not support dynamic overclocking.

The configuration of video outputs is almost standard: from the five of DVI-I, DVI-D, HDMI and 2x Mini DisplayPort for some reason excluded DVI-D. The additional power is supplied by one 8-pin and one …
