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 …

The CPU Cooler by MSI, Compatible with Socket AM4

Since October stores in Japan have been offering their customers an MSI Core Frozr L CPU cooler, which can attract the consistent style connoisseurs, possessing mother boards of this trade mark, as well as potential purchasers of Socket AM4 mother boards and CPUs. According to MSI, one of the peculiarities of this cooler is its mount system compatibility with Socket AM4.



Besides, the MSI Core Frozr L model matches Socket AM2/AM2+/AM3/AM3+/FM1/FM2 and LGA 775/115x/1366/2011(v3) jacks. Still, its trouble-free fitting boards with Socket AM4 is able to draw the attention of demanding buyers.


It is well known, that not all existing CPU cooling systems can be mounted on Socket AM4 without being adapted in a proper way.

Dell Teases a Couple of IPS Monitors: P2417H & P2717H

Dell is about to launch a pair of monitors targeting office PC systems as well as standard home multimedia systems. The P2417H (24-inch display) and the P2717H (27-inch display) are fitted with a high-quality IPS panel with an integrated LED backlight. Both models feature 16:9 aspect ratio and Full HD resolution – 1920x1080 pixels.



The implemented array offers 6 ms response time in GtG environment. The top brightness index makes up 250 & 300 cd/m2 respectively. Both new-comers share the widest possible viewing angles (178/178 degrees) and are able to display up to 16.7 million colors. Static contract index equals to 1000:1, whereas dynamic ratio approximates 4M:1.


Dell P2417H and Dell P2717H boast a rich inventory of external interfaces: a pair of USB 2.0 ports, the same number of USB 3.0 ports, one DisplayPort 1.2, one HDMI 1.4 port, and one analogue D-Sub port. The first display is thought to consume 19 W power, while its companion is known to consume 23 W power.
