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 …

Budgetary Chassis NZXT Tempest 210 Review

Product line of NZXT, an American hardware developer and supplier, is basically targeted at gamers and enthusiasts. Its chassis and power supply units prove to demonstrate highly-efficient characteristics and, in some terms, outstanding performance. Still, the company expands its customer audience by developing products for middle-end and entry-level consumer groups. Its latest chassis model Tempest 210 belongs exactly to the budgetary sector due to the reasonable correlation: quality – price. Being an entry-level product, NZXT Tempest 210 is ready to offer quite satisfactory facilities and performance.


Design of NZXT Tempest 210 chassis can be called classical. This is confirmed by all straight lines and standard framework. Grid-like frontal panel is the only distinguishing feature of the model. The rear panel is analogous to the majority of other classical enclosures. Tempest 210 is delivered only in black version to add universality to the model's utilization. …
