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 …

Nvidia to Showcase Its Newest GeForce GTX 650 Ti Boost Graphics Adapter

Today, 26 March, Nvidia is going to officially introduce its newest graphics adapter, codenamed GeForce GTX 650 Ti Boost. The release is a counter-move in response to the recently launched AMD Radeon HD 7790 adapter. With the purpose to enhance the competition, Nvidia equipped its graphics card with GPU Boost technology for a dynamic overclocking process.



Galaxy is the first to respond to the fresh release with its brand new product – Galaxy GeForce GTX 650 Ti Boost adapter. This model is furnished with 2 GB memory of GDDR5 standard (192-bit memory rail) and GK106 GPU with 786 CUDA cores. Frequency index for GPU equals to 980 MHz (boost frequency increases to 1033 MHz), for memory – 6008 MHz. Memory bandwidth is claimed to gain 144.2 Gb/sec.


Graphics card from Galaxy is thought to have a single SLI socket, one 6-pin PCI Express Power socket (additional power supply), and three different video interfaces: D-Sub, HDMI, and DVI. Cooling system consists of a two-slot …

Asus Teases Turbo GeForce GTX 1080 Videocard

Asus has just introduced Turbo GeForce GTX 1080 videocard with etalon frequencies & a modified cooler. The model is developed on Nvidia GP104-400 GPU (2560 CUDA, 160 TMUs, 64 ROPs) that operates at 1607/1733 MHz frequency. The integrated GDDR5 memory (8 GB, 256-bit interface, 320 Gb/sec bandwidth) runs at 10 GHz frequency.



The card is coated in a dark-gray cover with logo illumination. The PCB is designed with the help of Auto-Extreme technology as well as Super Alloy Power II hardware. The other peculiar feature is a totally revamped cooling system. As distinct from the etalon model, the Turbo version employs a single fan, based on dual ball-bearings, which pushes hot air away from the GPU.


The greenhorn comes equipped with a pair of HDMI ports for the connection of various devices, including VR-helmets. There are also DVI-D and DisplayPort 1.4 ports. The PCB features a single 8-pin power connector. Asus Turbo GeForce GTX 1080 supports GPU Tweak II & Xsplit Gamecaster …
