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 …

Intel Compute Stick With Intel Apollo Lake CPU

In the year of 2015 the Intel Company announced a mini PC with a completely new layout, named Intel Compute Stick. According to its dimensions it resembles a mobile 3G adapter or a slightly enlarged typical flash drive, though its functionality lets us consider this sample to be a fully-featured PC, which only needs to be connected to the monitor or TV-set through the HDMI interface.



At first the Intel Company and its partners released their versions with Intel Bay Trail CPUs, being later exchanged by the Intel Cherry Trail series solutions. In 2016 even more powerful models with Intel Core m3 and Intel Core m5 (Intel Skylake) CPUs appeared. One can expect, that in the second quarter of 2017 the Intel Compute Stick manufacturers will use the Intel Apollo Lake series chips.


At least two new Intel Compute Stick versions are to be released. The first model will feature 2 GB of RAM, 32 GB of ROM eMMC memory and the pre-set 64-bit Windows 10 Home OS. The second version will …

Deepcool to Release Neptwin V2 CPU Cooler

Deepcool Industries Co. LTD has enriched its production line with a new CPU cooler, entitled Neptwin V2. Featuring 125x136x159 mm dimensions, the model allows for the installation of up to four fans, combined with a nickel-plated base, six copper heat pipes and a two-section voluminous heatsink which consists of 80 ribs (40 ribs for each section).



This cooler is known to support all up-to-date platforms, developed by Intel and AMD. As distinct from the majority of rivals, the Neptwin V2 framework is ready to accept four fans which operate by means of PWM technology. The base version comes with only two fans. The first one – Deepcool Wind Blade 120 – is equipped with a blue backlight; its rotational speed range varies from 900 to 1500 RPM. The second fan rotates at 1300 RPM. An overall noise level fluctuates within 21.4-32.1 dB boundaries.


It should be mentioned that total airflow volume produced by the fans might achieve 110.8-237.15 m/h. As a result, the cooler is …
