'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 …

Solid-State Drive OCZ Agility 4 Review

Up-to-date SSD manufacturers are inclined to employ MLC flash-memory with synchronous interface in their product lines. The implementation of exactly such memory interface allows balancing the advanced performance with moderate price. This is especially vital for SSDs with SATA 3 6Gb/sec interface. Nevertheless, some producers take the challenge to implement flash-memory with asynchronous interface in their drives. As a result, the final products go at more attractive price but with more modest speed characteristics. OCZ dared to overcome this speed drawback by releasing SSD Agility 4 series. The models included in the series are based on asynchronous flash-memory interface and, according to the company's words, prove to show quite decent speed index.

Chief Peculiarities

Despite the prevalence of SandForce controllers implemented in SSDs, OCZ decided to use quite different platform for its new series. Agility 4 employs Indilinx Everest 2 controllers which, in some way, …

MSI Unveils GeForce GTX 900 Gaming Graphics Couple

Following a long-lived trend in PC hardware market, MSI has unveiled its two new videocards of GeForce GTX 900 (Maxwell architecture) series just after Nvidia’s official release. The MSI GTX 970 Gaming 4G and the MSI GTX 980 Gaming 4G models boast both, identical and dissimilar features with their reference companions. But all in good time.

Videocards from MSI are characterized by analogous with Nvidia’s models memory subsystem. Hence, it has 4 GB of GDDR5 memory modules with 256-bit interface, 224 Gb/sec bandwidth, and 7010 MHz efficient clock frequency. Quite the contrary, both GPUs differ from the etalons, chiefly due to the integration of Gaming App brand utility; the latter enables GPUs to run in one of three available modes: Silent, Gaming and OC.

The MSI GTX 970 Gaming 4G operates at 1051 MHz/1114 MHz/1140 MHZ at the start (showings for three modes) but might be overclocked to 1178 MHz/1253 MHz/1279 MHz respectively. The MSI GTX 980 Gaming 4G runs at 1140 …
