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 …

The Colorful company has put a new product on the list of unconventional system boards. The name of the game is C.J1900A-BTC PLUS V20, which defines an extraordinary mother card for mining purposes.



The specialty features a unique construction with two separate sections available and no need for PCIe riser cables. At first glance it reminds a part of a PC-board with connectors, but not an ordinary main board. However, that is so when exploring the first part of the device. The second section represents an expansion board with the PCIe interface, holding a processor, a core memory slot and a set of required ports.



C.J1900A-BTC PLUS V20 allows to mount eight video cards. The board connected is based on the Intel Celeron J1900 CPU. One can install two drives using the SATA and mSATA ports. Among connectors present we may distinguish USB 2.0 (x2), HDMI and Gigait Ethernet (x2) interfaces.

The ADATA manufacturer has officially introduced two new external memory units, called ADATA HV300 and ADATA HD330.

 

ADATA HV300 obtained a stylish and thin (10.3 mm only) case. The other novelty, instead, got a protected shockproof design with the absorbing silicone covering. Both devices are available in 5 capacity variants – 1, 2, 3, 4 and 5 TB, to be more precise. Besides, all of them have a USB 3.1 port.

 

The two specialties by ADATA are supplied with a special sensor, registering shocks or cases of falling down during operation and terminating the inner drive activity to prevent data corruption or bad-sectors emergence. Happy owners of ADATA HV300 and ADATA HD330 may utilize brand HDDtoGO software for free, so they get a possibility to encrypt data with the help of 256-bit AES-algorithm.

 

The novelties will be shipped in various colour versions with the interface cable added to the supply kit. Prices are unveiled yet.
