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 …

Cryorig Readies a Pair of Uncanny Ola & Taku Chassis

Cryorig, a renowned designer of CPU coolers & fans, decided to expand its expertise by developing a couple of one-off PC chassis – the Ola and the Taku. Both greenhorns are differentiated by an extraordinary design, a far cry from traditional tower-cases. They are thought to support mini-ITX motherboards and come with a pair of drive bays (2.5-/3.5-inch). The models will be promulgated within the framework of the Computex 2016.

Presumably, Cryorig Ola’s cylindrical case features 378.5x226x205 mm dimensions. Cryorig Taku positions itself as a monitor stand, featuring 567x270x134.8 mm dimensions. Their internal layout allows for the installation of SFX power supply units (130-mm long) as well as 280/240-mm long videocards. The permissible height of the CPU cooler makes up 82 mm & 42 mm correspondingly.

To continue, the Ola is considered to support CPUs with up to 100 W TDP. The case comes with multiple ventilation grids which are called to improve airflow. The top facet …
