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).

To continue, GeForce GTX 770 …

Zalman ZM-GVM Introduces ZM-GVM Bronze PSUs

Zalman adds another series of power supply units to its portfolio. The ZM-GVM series is represented so far by three semi-modular units of 500 W, 600 W and 700 W capacity. They correspond to ATX12V 2.31 standard and boast 80Plus Bronze certificate since their efficiency achieves 88%. The new-comers are able to operate in a wide range of input voltages (115-230 V), featuring only a single +12V rail.

Zalman ZM-GVM units employ dual forward converter as the basis. Semi-modular design presupposes permanent fixture of the main cables and demountable construction of optional cables. Efficient cooling is the task for a low-noise 120-mm fan, whereas sustainability of the units is entrusted to the advanced protection system.

Zalman ZM500-GVM PSU accommodates 1x 24-pin connector, 4+4-in ATX 12V, 3x MOLEX, 5x SATA, 1x FDD, and 2x 6+2-pin PCI Express connectors. The ZM600-GVM offers 4x MOLEX and 6x SATA connectors in addition to the base ones. The senior ZM700-GVM houses 4x MOLEX …
