MSI Offers H87I AC Motherboard for Demanding PC Builders

MSI has made a pleasing presentation for all builders and enthusiasts who would like to create a small-sized but highly efficient gaming or multimedia system. The MSI H87I AC is designed in mini-ITX form-factor, featuring 170x170 mm dimensions only. The core of the board is Intel H87 Express chipset that supports all Haswell CPUs with LGA1150 socket. According to the latest data, the model is already available in the European market for approximately 102 EUR.



The H87I AC accommodates two DIMM slots, available for the incorporation of DDR3 modules with the maximal frequency of 1600 MHz. The latter might work in a two-channel mode and reach 16 GB capacity. Disk subsystem is organized by means of four SATA III 6 Gb/sec ports, which allow for the creation of diverse RAID configurations (i.e. 0, 1, 5, 10, AHCI).


Expansion is realized due to a single PCI-e 3.0 x16 connector and one mini-PCI-e (half-size) connector for network modules. Network abilities are supported by one …

The official announcement of the motherboard Biostar Hi-Fi Z77X

Company Biostar, taking the example of the motherboard market leaders, manufactures the product for the audiophile — Biostar Hi-Fi Z77X. In the latest model are involved: the processor socket LGA1155, the flagship chipset for the platform (Intel Z77), three full-height PCI Express x16 and 13-channel subsystem of CPU power. The developer promises high quality audio through 7.1-channel HD Blue-ray audio codec ALC898, Technology THX TruStudio Pro, Hi-Fi Ground (multi-layer PCB with protectors properties), and Puro Tone (signal / noise ratio — 110 dB), as well as resistors, Hi-Fi Resistor with tin oxide capacitors and Hi-Fi Cap.



Four slots for memory with dual access are designed for installation of modules DDR3-1066/.../2600 totaling 32 GB. In addition, the construction of SLI and CrossFire configurations using the formula «x8 + x8» is possible. The lower slot PCI-E 2.0 x16 x4 is good to use for high-speed SSD-drives, and «external» controllers. PCB has six ports Serial ATA …

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 …
