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 …

3D-monitors D2343P-BN and D2743P-BN on matrix IPS from LG

The South Korean manufacturer of digital technology LG enlarged range of branded monitors by two nontrivial models — D2743P-BN and D2343P-BN. Title of the article clearly points out their main advantages — the support of stereoscopic image display quality and availability of the matrix In-Plane Switching with angles of 178 ° / 178 ° horizontal and vertical. LG D2743P-BN has a diagonal of 27 inches, D2343P-BN — 23 inches. The nominal resolution of both displays is 1920x1080 pixels, or, as is now fashionable to say, «Full HD».



New items stand out from their analogues by low power consumption. LG D2743P-BN, on average requires 27 watts of power, and D2343P-BN — 25 watts. Monitors support the «acceleration» of the matrix (Overdrive) to 5 ms, like TN + film screens. Another interesting feature of debutants is the built-in technology Super Resolution, which adds sharpness to blurred images. One click of the 2D-image on the screen can be turned into 3D. In order to view …

Meeting Four New PSU Series from LEPA

Ecomaster has recently expanded its production line by four new PSU series under LEPA brand name. Codenamed P, GM MaxGold, GM MaxBron and MX, this quadruple is targeting high-end, middle-end, and mainstream market segments. It is noteworthy that each of the series involves several models of various power and efficiency showings to meet the power supply requirements of diverse PC systems.


LEPA P


P series is attributed to the high-end market segment and consists of three high-capacity models: P1700-MA, P1375-MA and P1050-MA with 1700 W, 1375 W and 1050 W correspondingly. The triple features totally modular cable management system and identical cooling system, introduced by 135 mm low-noise fan on ball bearing. Super high efficiency level allowed all power supply units within the series to receive 80Plus Platinum certificate.


LEPA GM MaxGold


GM MaxGold series boasts 80Plus Gold certificate due to high power efficiency. The series includes five models that feature a …
