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 …

Kingston Showcases High-Capacity SSDNow KC400 Drives

Kingston has expanded its SSDNow lineup of solid-state drives by KC400 series. It entails four high-capacity 2.5-inch models: 128 GB, 256 GB, 512 GB and 1 TB. All of them are based on a 4-core 8-channel Phison 3110 controller and SATA III interface. The new-comers feature 100.1x69.8x7.0 mm dimension only and are shipped with a 5-year’s limited warranty.

Kingston SSDNow KC400 drives support SmartECC technology that serves for the maximal protection of data purposes. In addition, they accommodate SmartRefresh technology that saves the data from reading errors. The availability of onboard dedicated software ensures that the models could restart after emergency power shutdown.

All SSDs boast quite high cumulative volume of written data. The drives are able to operate in a wide range of temperatures (from -40 to +85). Their maximal power consumption index equals to 3.74 W on reading and 0.255 W in idle mode.

Moreover, the KC400 series offers unprecedented performance …

New Mini-ITX Motherboard H87E-ITX/ac from ASRock

ASRock, a Taiwanese manufacturer of motherboards, is eager to introduce its new elaboration – motherboard H87E-ITX/ac. The new-comer is designed in a compact mini-ITX form-factor and is destined for the creation of compact desktop systems. Chipset Intel H87 Express in combination with Intel Core (4th generation) LGA 1150 processors provide for utmost stability and high performance in the majority of working modes.

ASRock H87E-ITX/ac houses two slots for RAM memory modules of DDR3 type; the maximal volume of supported memory might achieve 32 GB. The board takes power by means of 24-pin ATX and 8-pin EPS connectors. Digi Power system, featuring DrMOS voltage regulators, allots four phases for providing power supply to the CPU. Expansion of facilities becomes possible due to a single PCI Express 3.0 x16 slot, a single miniPCI Express slot, a single eSATA port, and six SATA III 6 Gb/sec ports.

Network facilities are guaranteed by gigabit Ethernet port, Bluetooth 4.0 module, …
