Such options exceed those integrated into a reference model, AMD Radeon HD 7970 GHz Edition, and are able to ensure a dramatic increase in performance.



Technical Peculiarities


Sapphire decided to base its flagship model on GPU AMD Tahiti with an integrated delimiter which lowers the clock frequency on the overshoot of thermal threshold. Its standard frequency equals to 1050 MHz, nominal frequency – 1100 MHz; sill, this GPU features Lethal Boost options that increase the frequencies up to 1200 MHz. This graphics card is …

Asus Announces ROG Poseidon GTX 780 Adapter with DirectCU H2O

Asus has officially introduced a new add-on to the GTX 780 graphics cards series – the ROG Poseidon GTX 780 (codename: Poseidon-GTX780-P-3GD5). The new-comer is initially differentiated by the incorporation of a hybrid DirectCU H2O cooling system, as well as of prime-quality components. The heart of the model is Nvidia GK110 GPU with 2304 CUDA cores. It operates at 1006 MHz. the GPU is accompanied by 3 GB of GDDR5 memory (384-bit bus), running at 1502 MHz (6008 MHz – efficient).



Asus ROG Poseidon GTX 780 employs a qualitative printed circuit board that boasts 10-phase Digi+ VRM digital power subsystem. Reliability of operation is ascribed to Black metallic solid-state capacitors, ferrite chokes with Super Alloy Power support, and classy transistors. They take care of the card’s lifespan, which, according to some reports, is five times longer than rival models feature.

The New Fan from Antec – Rainbow 120 RGB – Will Be Available at the Price of 15 EUR

The range of Antec chassis fans has been widened by the Rainbow 120 RGB model. Its name suggests, that this product is of 120 mm typical size. LED backlighting of Rainbow 120 RGB renders up to 256 shades to produce dynamic effects or covers up to seven colours in the static mode. Moreover, the setup chosen by the user is supported after the PC switching off. The backlighting is adjusted just by pushing a little button.



The special blade configuration directs air flow to the outer side, thus increasing the static pressure level and enhancing the process of flows distribution inside the system unit. Fluid bearings extend the service life, and fan rubber pads at the places of mounting holes lower the vibration and noise level.


The top rotational speed of Rainbow 120 RGB is 1,200 rpm, and the air flow capacity equals to 1.2 m3/min. This device possesses a three-pin power supply connector and features the 12 V nominal voltage. The noise factor is not higher than 24.8 dBA.
