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 …

ASRock FM2A88M-HD+ to Support the Latest AMD Kaveri APUs

ASRock has recently announced a new series of motherboards that are based on the prime-class AMD A88X chipset, targeting Socket FM2(+) CPUs of Trinity and Richland generation. Moreover, they are supposed to support the new-gen AMD Kaveri APUs with Steamroller microarchitecture. One of the most outstanding models within the series is FM2A88M-HD+ motherboard, which features a large amount of slots and sockets. At the same time, it remains a cost-efficient solution.

ASRock FM2A88M-HD+ is designed in a micro-ATX form-factor, featuring 234x183 mm dimensions. The company claims that this model is able to accommodate DDR3 RAM with 2133 MHz frequency, housed in two DIMM slots. Therein, the maximal memory capacity might achieve 32 GB. Hardware base consists of prime-quality solid-state capacitors and durable chokes. Three expansion slots are introduced by one PCI, one PCIe 2.0 x1, and one high-speed PCIe 3.0 x16; the latter demonstrates up to 15.75 Mb/sec bandwidth.

NEC Intros EA244WMi Monitor in Two Color Versions

NEC, a renowned Japanese monitor designer, introduces a new 24-inch monitor with IPS panel type. Models EA244WMi and EA244WMi-BK are considered to be a single product, delivered in two color variations: black and white. Both monitors feature 1920x1200 resolution and 16:10 aspect ratio. The display is characterized by the availability of a power-saving LED backlight and 6ms (GtG) response time.

Irrespective of the seemingly unassuming design, EA244WMi is notable by a multi-functional stand. Its framework permits the customer to change the display tilt from -5 to +30 degrees, rotate it at 340 degrees left and right, rotate it at 90 degrees in vertical surface, and alter its height level. The display frame accommodates a couple of 1W stereo speakers, while its rear panel is furnished with mini-jack 3.5 mm audio slots, four-port USB 2.0 hub, and a set of video outputs (mini-D-Sub, DVI, DisplayPort, HDMI).

Other specifications of NEC EA244WMi include:
