HIS Radeon R9 290 IceQ X2: Graphics Card with an Offbeat Cooler

HIS has recently replenished its Radeon R9 series of graphics cards with a new model – the Radeon R9 290 IceQ X2. Based on AMD Hawaii Pro chip, this card is a combination of an ultimate efficiency and an offbeat design. The integrated GPU runs at an etalon frequency — 947 MHz. No changes have been incorporated into the frequency mode of GDDR5 memory: the 4 GB memory with 512-bus interface runs at nominal/effective 1250/5000 MHz frequency.



The major peculiarity pertained to the model is the employment of a proprietary two-slot cooler, codenamed IceQ X2. It consists of a spacious copper base (40x47.5 mm), a large aluminum heatsink, a pair of 89 mm fans, and five nickel-plated heatpipes: 2x 8 mm and 3x 6 mm. The cooler also accommodates additional heatspreaders, which dissipate heat in memory and VRM sections. Moreover, the framework boasts a dedicated stiffening plate that reduces loading on the printed circuit board.

Modular Power Supply 650W Chieftec A80

Evaluating the effectiveness of modern computer power supplies, the most attention is paid to their coefficient of performance (COP) at a given load — usually means of 20%, 50% and 100%. At the same time, not less important requirement, established by standard 80PLUS should be considered. That means — the preservation of this level of performance for all occurring in the world supply voltage variations, that is in the range of 100-240 V.



The standard rules of 80PLUS at different levels (Basic, Bronze, Silver, Gold, Platinum, etc.) are performed for two voltage 115 V and 230 V. In both cases, the normalized PS should show the efficiency of not less than specified for each category level. Not usual power supply CTG-650C model of the new A-80 series from the Chieftec company is interesting in that it has officially claimed efficiency of 85% or more, but only for nets 220-240 V.


As the advantages of such solution can immediately be noted a lower price, due to less stringent …

ECS Implements Advanced Technologies in Z77H2-A5X Deluxe

ECS is going to release a new motherboard Z77H2-A5X Deluxe developed under the latest technologies with the highest quality standards. The model belongs to ECS Black Series and is predestined specifically for experienced users, overclockers, and just demanding customers. The board is designed in ATX form-factor and employs high-quality semiconductor capacitors, load-proof fins and heat pipes, as well as triple goldish coverage. It is compatible with Intel Ivy/Sandy Bridge processors and LGA1155 socket.



The motherboard inventory embraces 32GB of two-channel DDR3 memory (4 DIMM), the nominal clock frequency of which equals to 1866 MHz; this index might be increased to 2133 MHz on overclocking activity. The board accommodates two PCI Express Gen2 x16 slots (for CrossFireX support and graphics card upgrade), two PCI Express Gen2 x1 and the same number of PCI slots for the connection of other cards. Besides, Z77H2-A5X Deluxe is notable for a good potential in mutual operation with …
