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. …

Gigabyte Shows Off a Bespoke GTX 970 Graphics Card

Gigabyte has intrigued its fans by the design of an unusual videocard – the GeForce GTX 970 (GV-N970TTOC-4GD). It is based on Nvidia GM-204-200-A1 GPU (Maxwell) but with overclocked frequencies. The core operates at 1101 MHz/1241 MHz instead of etalon 1050 MHz/1178 MHz. The GPU is accompanied with 4 GB of GDDR5 memory (256-bit bus) that runs at 7010 MHz efficient clock frequency.

Gigabyte GeForce GTX 970 is distinguished by the implementation of Twin Turbo Fan cooling system. It consists of three copper heatpipes with direct touch technology, an aluminum heatsink, and a radial-flow fan; the latter grasps air from both sides of the adapter due to the shortened PCB design.

As a result, the airflow increases by 24%, whereas the cooling effect enhances by 29%. Thanks to this, the card is thought to be an optimal solution for Nvidia SLI configurations.

It should be noted that this graphics card boasts a high-quality hardware base – Ultra Durable VGA. A set of external …

Sapphire Showcases Radeon HD 7870 GHz Edition Toxic Solution

Sapphire Technology Ltd. is going to release a new graphics card on Tahiti LE chip. Codenamed Radeon HD 7870 GHz Edition Toxic, the card is one of the first models to use the newest GPU, developed under 28 nm technological process. The suffix 'GHz Edition' in the model's name witnesses that the nominal GPU clock frequency exceeds the index of 1 GHz.

The core of Sapphire Radeon HD 7870 GHz Edition Toxic is based on Graphics Core Next architecture and contains 1536 current processors. The card's inventory involves 2GB of GDDR5 memory with 256-bit bus interface. The memory modules are known to operate at 6000 MHz frequency. GPU operational frequencies are still not clarified, but it's possible to assume that on activation of AMD PowerTune option the card will demonstrate some outstanding performance. In fact, analysts dare saying that this model is the most efficient one among all other solutions based on Tahiti LE chip.

Optimal thermal regime and airflow activity are …
