According to the preliminary specifications, memory cards Professional 400x SDCX UHS-I correspond to SD 3.0 standards and are designed under UHS-I technology. They will be delivered in 256 GB volume capacities. The claimed maximal data reading speed approximates 60 Mb/sec.


Professional 400x SDCX UHS-I is based of NAND chips manufactured under 20 nm technological process by Micron; their capacities equal to 128 Gbit. The development of these memory cards involved only progressive tools, such as the creation of …

Taking into account increasing needs of gamers and enthusiasts in a reliable power supply for gaming and multi-GPU systems, Thermaltake decided to replenish its Toughpower Grand series of PSUs with two new models. The 1050 W and 1200 W units feature a totally modular design and boast 80Plus Gold certificate, demonstrating up to 93% efficiency on workload. In order to vindicate durability, the company delivers the couple with a 7-year’s limited warranty.



Thermaltake Toughpower Grand devices accommodate high-quality hardware base, including 100% Japanese solid-state capacitors with a vast range of operational temperatures (up to 105 degrees). Both models come with a single +12V bus and handy ribbon cables. The 3 OZ Copper PCB implies the implementation of triple copper layer in the base of the PCB; this reduces heating and simultaneously enhances performance.


Both units are known to support C6 and C7 power-saving modes for Intel Haswell processors. In addition, they are …

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 …
