Nvidia Debuts with GeForce GTX 770 Graphics Adapter

Trailed by the flagship GeForce GTX 780 model, Nvidia officially launches one more high-performance graphics adapter of 700 series, codenamed GeForce GTX 770. Albeit the two products are rather similar in design (i.e. the incorporation of identical two-slot cooling system), their layout differs considerably. First of all, GTX 770 employs less efficient graphics core Nvidia GK104-425-A2 (28 nm) with 1536 CUDA cores, 128 TMUs, and 32 ROPs. At the same time this GPU operates at higher frequencies: 1046 MHz (nominal), 1085 MHz (dynamic).

Nvidia’s new entry comes either with 2 GB or 4 GB video memory modules of GDDR5 type. They employ 256-bit interface and ensure high bandwidth of 224 Gb/sec. Memory operational frequency is truly striking, demonstrating up to 1752 MHz (nominal) and up to 7010 MHz (dynamic) index. It should be noted that models with 4 GB modules will cost $50 more than those with 2 GB items (the recommended price makes up $399).

Three New PC Cases from Lian Li for mini-ITX Motherboards

Lian Li has recently introduced three new PC chassis compatible with the motherboards of mini-ITX standard. Codenamed PC-Q27, PC-Q28 and PC-Q30, these cases replenished the 'Q' series and are called to replace more out-dated predecessors. The first two models in the row replace the earlier launched PC-Q07 and PC-Q25, while PC-Q30 is only a prototype that substantially differs from from its companions.

All three models are distinguished by a quite new approach to the motherboard fixture. Hence, instead of traditional trays, Lian Li employs two rails that fix the board. What is more, the designer has implemented quite a different system of side panels mounting.

The first PC case, PC-Q27, features 200x321x240 mm dimensions and is estimated for the installation of a single 5.25-inch drive, two 3.5-inch bays that support the installation of drives of 2.5-inch form-factor. The integrated cooling system consists of a single frontal 120 mm fan.

The second model, PC-Q28, is …

SilverStone Debuts with SX700-LPT Power Supply Unit

SilverStone is readying to launch a powerful 700-watt PSU, entitled SX700-LPT. The new-comer boasts 80Plus Platinum certificate, since its efficiency level might reach 94%. The model is developed in SFX-L form-factor and supports Intel ATX 12V 2.4 standard. SilverStone has already listed the unit on its official site; thus, customers might expect the market launch in the nearest future.

SilverStone SX700-LPT employs a single +12V rail with the maximal output capability of 58.4 A. This power supply unit is able to operate within 90-264 V range at the peak power index of 750 W. If there is a need, it’s possible to use the entire power stock via +12V bus, rather than distributing it via +3.3 V or +5 V rails.

The model comes with a modular cable system. The inventory includes connectors for the connection of 9 SATA devices as well as 4 videocards with an additional 6+2-pin PCI-e connector. The unit is fitted with all necessary protection mechanisms, entailing SCP, OPP, OPT, …
