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 …

Chieftec Showcases Five New PSUs from Navitas Series

Chieftec, one of the largest German hardware manufacturers, has recently introduced a new series of power supply units, codenamed Navitas. The series is represented by 5 models: GPM-650C with 650W nominal power, GPM-750C with 750W nominal power, GPM-850C with 850W nominal power, GPM-1000C with 1000W nominal power, and GPM-1250C with 1250W nominal power correspondingly. All the products have won 80Plus Gold certificate, due to more than 90% efficiency in the high workloads.



Chieftec Navitas PSUs correspond to ATX12V v2.3 standard and support Intel Core 4th gen. processors that require little current strength on +12V rail in sleep mode. The models also support active power-factor correction option to provide for the maximal stability during operation. They are equipped with a composite cable system and a single +12V rail, estimated for the maximal current from 54 A to 104 A (this index depends on the unit’s power).


All five units are cooled down by 140 mm fans with PWM …

PSU Seasonic X-1250 SS-1250XM Review

Power supply unit Seasonic X-1250 is a senior product of X series that includes units from 400W to 1250W power. The two junior models are absolutely passive, while all other models feature hybrid cooling schedule. This implies that on conditions of little loading, the integrated fan stops its operation; and vice versa, when the loading is increasing, the fan's operation is more intense. PSU X-1250 is quite powerful to serve the needs of high-performance systems that require stable and efficient power to all key components.



Basic Features


Power supply unit Seasonic X-1250 is delivered in a spacious cardbox which contains a set of cables for the connection of PC components. The unit is housed in a dull black casing with stamped yellowish grid. The whole construction is 190 mm in length (+20 mm for cable connectors), so it won't suit compact-sized PC chassis. All basic specifications are indicated on the casing: the availability of +12VDC line that demonstrates 1248W power at …
