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).

Meet a New 4K Monitor from NEC

NEC is going to release one more 24-inch PC monitor but this time with the support for an Ultra HD 4K resolution of 3840x2160 pixels. Entitled MultiSync LCD-EA244UHD-BK, it is characterized by an outstanding visual performance and by a relatively high price tag (approximately $2900).

NEC LCD-EA244UHD-BK employs an updated IPS panel, equipped with GB-R backlight. The latter ensures a wider color gamut than traditional W-LED analogues. The panel is specified by 6 ms response time, widest viewing angles (178/178 degrees H/V), 350 cd/m2 brightness, and 1000:1 static contrast. Two in-built speakers (1 W each) provide for a high-quality audio production.


The connection with the video sources might be realized via six video ports: a pair of DVI-D, two DisplayPorts, and a couple of HDMI ports with MHL support. The availability of four USB (v.3.0) ports promotes for the …

PSU Seasonic X-1250 SS-1250XM Review

Power supply unit Seasonic X-1250 is a senior product of X series that includes units from 400W to 1250W power. The two junior models are absolutely passive, while all other models feature hybrid cooling schedule. This implies that on conditions of little loading, the integrated fan stops its operation; and vice versa, when the loading is increasing, the fan's operation is more intense. PSU X-1250 is quite powerful to serve the needs of high-performance systems that require stable and efficient power to all key components.



Basic Features


Power supply unit Seasonic X-1250 is delivered in a spacious cardbox which contains a set of cables for the connection of PC components. The unit is housed in a dull black casing with stamped yellowish grid. The whole construction is 190 mm in length (+20 mm for cable connectors), so it won't suit compact-sized PC chassis. All basic specifications are indicated on the casing: the availability of +12VDC line that demonstrates 1248W power at …
