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 Announces ROG Poseidon GTX 780 Adapter with DirectCU H2O

Asus has officially introduced a new add-on to the GTX 780 graphics cards series – the ROG Poseidon GTX 780 (codename: Poseidon-GTX780-P-3GD5). The new-comer is initially differentiated by the incorporation of a hybrid DirectCU H2O cooling system, as well as of prime-quality components. The heart of the model is Nvidia GK110 GPU with 2304 CUDA cores. It operates at 1006 MHz. the GPU is accompanied by 3 GB of GDDR5 memory (384-bit bus), running at 1502 MHz (6008 MHz – efficient).



Asus ROG Poseidon GTX 780 employs a qualitative printed circuit board that boasts 10-phase Digi+ VRM digital power subsystem. Reliability of operation is ascribed to Black metallic solid-state capacitors, ferrite chokes with Super Alloy Power support, and classy transistors. They take care of the card’s lifespan, which, according to some reports, is five times longer than rival models feature.


To continue, hybrid DirectCU H2O combines a traditional air cooler along with liquid cooling. The …
