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 …
Deepcool can be boldly attributed to the manufacturers that are constantly improving their mastery is the elaboration of hardware components. The company’s second revision of CPU cooler Ice Blade Pro is a bright confirmation of this statement. Codenamed Ice Blade Pro v2.0, this product is supposed to exceed its predecessor in performance, noise level and consumer appeal. But let’s start its reviewing from technical peculiarities.
