A Triplet of Waterblocks for Titan Z Graphics Solutions from EK Water Blocks

EK Water Blocks, a well-known Slovenian manufacturer of enthusiast-level liquid coolers for GPUs, has just introduced a triplet of waterblocks for the newly arrived Nvidia GeForce GTX Titan Z adapters. The EK-FC Titan Z – Nickel, EK-FC Titan Z – Nickel (Original CSQ) and EK-FC Titan Z – Acetal + Nickel models are sure to provide the maximal cooling at the highest frequencies both for dual- GPUs and memory chips. All the blocks come with a transparent acrylic cover and a lid from POM ACETAL plastic.



EK-FC Titan Z waterblocks are attributed to full-cover solutions. This implies that they efficiently remove heat not only from graphics cores, but also from GDDR5 memory chips, as well as from voltage regulators of VRM subsystem. Areas in direct contact with the GPUs are equipped with micro-channels of 0.7 mm width. The blocks maintain resistance to the coolant stream; hence, they might be employed along with low-power pumps.

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 …

Power Supply Unit Hiper Type M900 Review

The market of power supply units is full of beneficial options from a range of designers. Some of them are resplendent with new products rather often, the others release the units rather seldom but right on target. Hiper belongs exactly to the last mentioned designers, rejoicing its potential customers with only high-quality solutions. PSU Hiper Type M900 is a worthy representative of M series that is known to be efficient in the majority of operational modes. Let’s review this model in more details.



General Information


Hiper Type M900 is delivered in a small-sized cardbox with a convenient handle. The unit itself is housed in a matte black case with a spacious ventilation grid covering a high-performance fan. All key specifications can be found at the unit’s case: +12VDC rail is able to handle 900 W power at 75 A; the correlation of power on +12VDC rail with the total power makes up the maximal 1.0 index.
