Motherboard Gigabyte GA-F2A85X-UP4 Review

The second generation of AMD A-Series hybrid processors, announced earlier in October, are already integrated in a number of graphics solutions. The newly appeared products are compatible with Socket FM2 only and cannot be applied for Socket FM1 infrastructure. This implies that a number of motherboards lose their upgrade facilities and can't be updated with a new advanced solution. Still, the market is currently ready to present a few boards destined to operate with the updated AMD A-Series. Gigabyte is one of the pioneers in this respect, introducing its motherboard GA-F2A85X-UP4, developed specifically for Socket FM2.


Gigabyte GA-F2A85X-UP4 is designed in ATX form-factor with 305x244 mm PCB dimensions. AMD A85X chipset is a heart of the motherboard; it secures the compatibility with A-Series (second gen.) APU and Athlon CPUs in the implementation of Socket FM2. The overall TDP level claimed for the model is not more than 100W. The PCB allots four DIMM slots …

SilverStone Debuts with SST-ST30SF Power Supply

SilverStone Technology has recently introduced its newest SFX power supply unit. Codenamed SST-ST30SF, it features 125x100x63.5 mm dimensions and weighs 800 g only. The unit is estimated for 300 W power and is capable to demonstrate more than 81% efficiency in 230 V networks. High efficiency level allowed the model to gain 80Plus Bronze certificate.

The most uncommon feature ascribed to SST-ST30SF is that it can operate in passive mode if thermal conditions allow. The unit is equipped with a fan of 80 mm dimensional type; it starts rotating only when the surrounding temperature reaches 55 degrees. This promotes for a considerable power reduction and practically silent work when the fan gets disabled. An average noise level on active operation makes up 18 dB.

SilverStone furnishes the new entry with a single +12V rail, estimated for 22 A current. In its turn, +3.3V rail is estimated for 21 A current, while +5V rail – for 20 A current. It should be noted that this unit …

Cougar Vortex Fans: the Secret of Success

Nowadays a lot of hardware developers employ Vortex fans from Cougar in the design of various PC components, including CPU coolers and graphics cards. Such demand is primarily explained by an elaborate approach to the fans' framework construction. Profound testing is not the last thing to contribute to the company's success. Indeed, since the launch date in 2011, Vortex line has been enjoying great popularity throughout the world and, especially, on American and European markets.

Therefore, Cougar has designed unique fan impellers that ensure a balanced correlation between such parameters as static pressure, noise level and airflow. The implementation of aerodynamic elements on the internal part of the frame in combination with the grooves on the impellers are able to promote for an improved airflow focusing; this is achieved due to the acceleration of airflow in edge area.

All Vortex fans are based on a hydrodynamic bearing that provides for the prolonged lifetime and …
