QUMO Enters SSD Market with a New High-End Series

QUMO, a Japanese manufacturer of various PC components, decided to enter the SSD market to expand its production line. Its new SSD series is going to compete for potential customers throughout the world with already established and renowned suppliers to this industry. The series comprises 4 models of 60GB, 120GB, 240GB, and 480GB capacity. All of them are based on SandForce SF-2281 controller and use MLC NAND flash-memory (synchronous). Those SSDs are also known to support SATA III high-speed interface.

The advantage of QUMO drives is primarily seen in their reduced power consumption and heat dissipation. The drives are equipped with a range of dedicated technologies that protect them from overloading, humidity, and other unfavorable impacts. All models promote for the quick 'cold' activation, while traditional HDDs require some time for the spindle spinning. The user receives a chance to get quick access to a random sector, without the necessity of moving the head. Stable data …

WQHD Monitor Asus PB278Q Review

27-inch monitors were supposed to be quite an expensive solution several months ago, but today they are becoming more affordable due to the switch to LED technology. To say more, the army of displays with WQHD resolution (2560x1440) has grown from a few rare models to a line of products designed by a series of vendors. Asus joined this army with the introduction of monitor PB278Q. Its launch aroused great interest from the part of Asus devotees, as well as of all 'WQHD-targeted' customers.

Background Information

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 …
