Monitor Acer G276HL Review

Contemporary PC monitors are generally based on two types of panels with their variations: TN and IPS. The choice of panel depends on the product's class and destination. However, there are some monitors that employ rather rare arrays, like WVA, which appeared long time ago and now emerge in the market with a bit modified technologies. Acer G276HL is a representative of a small army of monitors based on WVA panel. WVA technology is not new but is called to fulfill all standard assignments to compete with more advanced options.



Specifications and Delivery


Acer G276HL features 27-inch display, 16:9 aspect ratio and 1920x1080 resolution. The monitor employs WVA panel type (6 ms response time) and is equipped with LED lighting. The claimed brightness equals to 300 cd/m2; this is an average index for a semiprofessional display. The number of displayed colors achieves 16.7 millions. It should be noted that the company does not provide much information about its new product, …

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 …

Review and testing of coolers GlacialTech Igloo H46 PWM and Igloo H58 PWM

The company GlacialTech Inc. known as a producer of cheap cooling systems aimed primarily at the lower and medium price segment. They are intended solely to cool the non-overclocked CPU. At the same time, GlacialTech has already made attempts to produce more efficient coolers that can cope with cooling of processors with high heat. It was the Siberia and Alaska, and F101 even before. Developing on its trend, the company has recently released two new models aimed at the medium price segment. It is about Igloo H46 PWM and Igloo H58 PWM.



Both coolers are available in the same decorated cardboard boxes, each on the right side shows the pictures of coolers and a list of supported platforms. On the other side of packaging there are specifications and key features of cooling systems. Packaging for both models are the same: it includes a steel universal clamping plate (backplate) with an adhesive base, two pairs of mounting with screws and key, two pairs of wire staples for installation …
