Release of Cooling System MK-26 from Prolimatech

Prolimatech made one more step to the leadership in cooling system segment by releasing a new cooler MK-26 last week. The new product is primarily intended at cooling GPUs integrated in graphics solutions developed by Nvidia and AMD. This model is differentiated by perceptibly voluminous dimensions which reach 230x146x47 mm. The nominal delivery set of MK-26 includes the most essential components, along with the brand PK-3 thermal compound.

The framework is designed with the efficiency and performance in mind. The cooler has got a nickel-based bottom part and six heat pipes. In their turn, the pipes accommodate two arrays of aluminum ribs which are manufactured under Buckle Fin technology. With the aim to enforce the performance, the user is able to locate a couple of 120 mm or 140 mm fans on the radiators. Graphics card together with this cooling system takes only two slots on the motherboard.

Moreover, according to the manufacturer's words, Prolimatech MK-26 is capable …

Corsair Introduces HXi 80Plus Platinum Power Supply Units

Corsair, a multi-profile American company, starts shipping new high-end PSUs of HXi series. The series currently combines three models with a totally modular design and the employment of Japanese electrolytic capacitors. Corsair HXi 750 W, Corsair HXi 850 W and Corsair HXi 1000 W models are distinguished by the highest efficiency of 91% that results in the conferment of 80Plus Platinum certificate.

Corsair HXi power supply units demonstrate compatibility with Intel Core CPUs (4th generation) and AMD’s latest APUs. The triple totally corresponds to ATX standard of the latest version. Cooling of all internal components is realized due to a low-noise 140 mm fan, based on a fluid-film bearing. Moreover, the implementation of Zero-RPM Fan Mode enables the blades to rotate only on the load pickup.

The units are furnished with a large set of protection tools, saving the layout from off-nominal conditions: voltage overloading, power overloading, input voltage overloading, …

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 …
