Graphics Card Gigabyte GeForce GTX 680 Super Overclock Review

The launch of graphics solutions with WindForce 5X cooling system stirred a real boom in the market, giving a special tribute to the products developed by Gigabyte. The company launched two adapters this summer with the implementation of WindForce 5X system and now introduces one more card on its basis. Model Gigabyte GeForce GTX 680 Super Overclock can be called a paragon of efficient performance, overclocking and cooling activities.



Design


Graphics card GeForce GTX 680 Super Overclock features 295x120x64 mm dimensions and rather unusual design. Instead of common fans on the frontal board Gigabyte covered PCB and elements of cooling system by a metallic cover with decorative holes; the rear board is also covered by a metallic plate. The top board is only partially covered by the lid that hides a line of five fans, while the bottom board unveils a voluminous heatsink with heatpipes. The implemented circuit board is originally designed with a reinforced power supply …

XFX Teases Radeon HD 7990 Triple Dissipation Graphics Card

XFX has introduced its own version of Radeon HD 7990 — a top-tier graphics adapter from AMD. As distinct from the other companies that incorporated only some inconspicuous changes into their products, XFX has approached to the card’s modification with a violent zeal. As a result, today everyone has a chance of examining its Radeon HD 7990 Triple Dissipation card that employs two Tahiti XT GPUs, elaborated on Graphics Core next architecture.



Each Tahiti XT chip comes with 2048 stream processors and 3 GB of GDDR5 memory. This implies that the total memory capacity makes up 6 GB. GPUs run at 950 MHz clock frequency, but have the potential of achieving 1000 MHz frequency on overclocking. As for the memory, it employs 384-bit bus and runs at an efficient 6 GHz frequency.


To continue, all the components of Radeon HD 7990 Triple Dissipation are housed on an original PCB, designed by XFX. Connection with the PSU is realized via a pair of 8-contact power sockets. The rear …

Meet Pure Power 9 CM Top Series of PSUs from Be Quiet!

Be Quiet! enters the market with a new series of power supply units, entitled Pure Power 9 CM. The lineup includes models of 400 W, 500 W, 600 W, and 700 W power. All of them boast the implementation of Active Clamp + SR topology with high-quality hardware base. Besides, the manufacturer decided to ditch group mechanism of voltage stabilization; this promoted for more efficiency which index achieves 91%.



High efficiency level allowed Pure Power 9 CM units to receive 80Plus Silver certificate. The 12V bus is divided into two lines with the maximal load capacity. Cooling process is attached to a single low-noise 120-mm fan, based on rifle bearing (100 thousand hours MTBF). Its maximal rotational speed varies within 1060-1680 RPM range.


To continue, Be Quiet! has incorporated into the models all possible security mechanisms, including OPP, SCP, UVP, OCP, and others. The units come with an additional Surge Absorber filter that protects the circuitry from voltage surges. …
