Rosewill Introduces PSU Line of 80 Plus Platinum Standards

Rosewill, Californian hardware manufacturer, has gladdened its potential customers with a new PSU line codenamed Fortress. The major peculiarity of this line is that all products are characterized by rather high efficiency coefficient: up to 94% in 230 V alternating current networks. The new line involves models of 450W, 550W, 650W, and 750W showings which have already received 80 Plus Platinum certificate.



Low power dissipation is achieved exactly due to the high efficiency which reduces ventilation demands immensely. The employment of 135 mm fans provided for the perceptible decreased of noise. Those features are considered to be the basic attraction for the customers.


All four models in Fortress line are developed according to a similar scheme with a single 12 V bus. The chief differentiation between the models lies in the output capacity and a cable set. Hence, the high-order PSU is capable to give current of up to 62.5 A; in the aggregate with the available 4 …

New Gigabyte Radeon HD 7970 operates at a frequency of 1100 MHz

Gigabyte presented a new overclocking model of video card Tahiti XT, designated as GV-R797TO-3GD. In comparison to the current Radeon HD 7970 OC (GV-797OC-3GD), the newcomer has some advantages. In particular, it is known that the graphic adapter is based on the graphics chip Radeon HD 7970 GHz Edition that is selected. The clock frequency of the accelerator is increased from 1000/5500 MHz (core / memory) to the 1100/6000 MHz, comparing GV-797OC-3GD. Standard values, recall — 925 MHz GPU with chip and 5500 MHz with GDDR5 microchip.



Externally the video adapter has no changes: the PCB soldered 3 GB of memory, which combines with the GPU on a 384-bit brace. The number of stream processors is unchanged — 2048 units. The design of printed circuit board includes electrical components Ultra Durable VGA. High-effective WindForce 3X cooler consists of a copper base, a few copper heat pipes and three 80-mm fans.


Unlike its predecessor, Gigabyte GV-R797TO-3GD has a gold plated …

Asus Introduces a New Powerful Motherboard Z87-A

The line of Haswell-compatible motherboards from Asus has been recently replenished with a new model – Z87-A. The new-comer is supposed to be the most ‘customer-friendly’ board, due to the correlation of incorporated facilities and price: based on the prime chipset (Intel Z87) on Socket LGA1150 platform, this board boasts an extreme functional combined with the price of $150 only. Thus, it might become a perfect solution for a powerful gaming PC.



Motherboard Asus Z87-A is elaborated in ATX form-factor and supports Intel Core i3, i5, i7, Pentium, and Celeron processors. Memory is represented by four DDR3 DIMM slots that are able to run at the maximal 3000 MHz frequency. Their overall capacity might achieve 32 GB. CPU power supply subsystem involves 8 phases; this is quite enough for a full-scale overclocking. Audio facilities are ensured by the integrated 7.1-channel Realtek ALC892 controller. Network facilities are backed by a separate gigabit Realtek 8111GR controller.
