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 …

Palit to Release GTX 1070 JetStream & GameRock Videocards

Following the official release of Nvidia’s GeForce GTX 1070 graphics adapter, the company’s partners have started unveiling their own modifications. Hence, Palit is about to launch four videocards, based on Pascal microarchitecture: GTX 1070 JetStream, GTX 1070 Super JetStream, GTX 1070 GameRock & GTX 1070 GameRock Premium Edition. All greenhorns employ GP104-200 GPU (16 nm, FinFet) with 1920 CUDA, 64 ROPs and 120 TMUs.



These videocards feature an 8-phase VRM system that uses a reliable hardware base, including solid-state capacitors and DrMOS chips. The GPU is accompanied by 8 GB of GDDR5 memory; its clock frequency across the line makes up 2.0/8.0 GHz (256 Gb/sec bandwidth) but for the GameRock Premium Edition model that delivers 2125/8500 MHz frequency & 272 Gb/sec bandwidth.


Cooling of all key components is provided by 2.5-slot coolers. They entail a copper base, a few copper heatpipes, a dual-section aluminum heatsink as well as a pair of 100 mm fans with …
