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 …

Greeting Small-Sized J1800I Motherboard from MSI

MSI has recently added J1800I model to its mini-ITX motherboards inventory. The new-comer features 170x170 mm dimensions and is characterized by a low power consumption level. This makes it a desirable acquirement for builders of small-sized, power-efficient PC systems and multimedia devices. The board boasts Military Class 4 design that involves high-quality hardware components, including Dark Chokes and solid-state capacitors.

MSI J1800I is based on Intel Celeron J1800 CPU (22 nm) that runs at 2.41 GHz frequency but might be overclocked to 2.58 GHz. It consumes only 10 W power, being cooled down by a single aluminum heatsink. The PCB accommodates two SO-DIMM slots for two-channel DDR3 memory modules with the maximum frequency of 1333 MHz and the maximum capacity of 8 GB.

To continue, the hardware inventory embraces two SATA II 3 Gb/sec ports for the connection of drives. The availability of one PCI Express 2.0 x 1 slot enables the connection of a supplementary expansion …

Greeting Kingston SSDNow mS200 Solid-State Drive

Kingston Technology, a large-scale developer of varied memory solutions from California, announces the launch of a new solid-state drive from SSDNow series, codenamed mS200. Currently, the model is available in two larger versions of 240 GB and 480 GB. Both new-comers are designed in mSATA form-factor, featuring 50.88x30 mm dimensions. Upon the whole, their dimensions are 8 times smaller than those imposed to standard 2.5-inch products.

Kingston mS200 are targeting budgetary segment of laptops, tablets and ultrabooks. Nonetheless, the drives are able to demonstrate high performance and allow the user to install two items within one system at a time in order to enlarge the storage volume. The new SSDs support Intel Smart Response Technology, TRIM, S.M.A.R.T., as well as 128-bit automatic encoding; they are thought to dramatically enhance the performance.

To continue, the greenhorns employ SATA III 6 Gb/sec interface and are based on LSI SandForce 2281 controller. In keeping …
