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 …

Asus Boasts a New ROG Swift PG278Q Gaming Monitor

Asus has begun a new season with the introduction of one more ROG series representative – the ROG Swift PG278Q PC monitor. This 27-inch model outstrips the competitors by a number of exclusive facilities, including an increased refresh rate (starting from 120 Hz), a minimal response time (1 ms only), a true WQHD resolution, and support for Nvidia G-Sync technology. In keeping with the company’s strategy, the monitor is oriented primarily on gamers; however, all fans of high-end imaging will find it a godsend.

To begin with, it must be stressed that Asus ROG Swift PG278Q is the first ever display with WQHD resolution (2560x1440) that supports advanced G-Sync options. These options are thought to synchronize the screen refresh rate with the GPU frames output rate. Thanks to this, there is no tearing or output latency; instead, the gamers enjoy more productivity and a really swift response. The model accommodates DisplayPort v.1.2 in order to communicate with compatible …

Galaxy Unveils a Shortened Version of GeForce GTX 760 Adapter

Galaxy Microsystems, a reliable partner of Nvidia, has recently unveiled its own, shortened version of GTX 760 graphics adapter. Codenamed Galaxy GeForce GTX 760 GC Mini, the card employs a reference GK104 GPU (28 nm), but is differentiated by an original PCB and a factory overclocking. The implemented circuit board features 193 mm length dimensions and is elaborated on a blue textolite.

The new-comer is furnished with 1152 CUDA cores that run at 1019 MHz but can be overclocked up to 1084 MHz. Video subsystem is introduced by GDDR5 modules with 256-bit interface. The overall capacity of modules makes up 2 GB. The GDDR5 demonstrates rather striking performance, considering the card’s middle-end destination: the modules are able to gain 6008 MHz clock frequency.

Power supply is organized according to 5+2-phase scheme, where five phases are allotted to GPU. A pair of 6-pin PCI Express Power connectors is used to provide additional power supply to the card. I/O interface …
