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 …

Nvidia Announces Quadro K6000 Professional Graphics Solution

Nvidia is going to release a new graphics card for professional use from Quadro series. Entitled Quadro K6000, it is targeting high-performance workstations, due to an uncommon computing efficiency with 5.2 TFLOPS single precision. This graphics adapter fully utilizes the computing possibilities of GK110 GPU and accommodates 12 GB(!) memory to lead across the segment.

Nvidia Quadro K6000 is based on GK110 graphics core (Kepler 28 nm architecture). As distinct from mainstream customer-oriented versions with neutered core – Titan, GeForce GTX 780/770 – this model employs a full-fledge core. This results in the augmentation of CUDA cores up to 2880 items, ROPs — up to 48 items, and TMUs — up to 256 items. GK110 here runs at 900 MHz.

In reference to GDDR5 video memory, its overall capacity makes up 12 GB, which is twice more than mainstream processors have. Its nominal clock frequency equals to 1502 MHz, while its effective index rises up to 6008 MHz. The connection …

Gigabyte Showcases GA-Z170X Gaming 3 Mainboard

Gigabyte expands its line of gaming products with a new ATX motherboard, entitled GA-Z170X Gaming 3. The key peculiarity ascribed to the model is the support for the latest Intel Skylake-S CPU (14 nm) with LGA 1151 socket. The new-comer takes Intel Z170 chipset as the basis and draws power via 24-pin ATX as well as 8-pin EPS power sockets. Besides, the board belongs to the mainstream customer segment, so its price won’t go higher than $188.

Gigabyte GA-Z170X Gaming 3 is furnished with 7-phase VRM, four slots for DDR4-3400 MHz RAM (two-channel) of up to 64 GB capacity, a pair of PCIe 3.0 x16 slots for the installation of graphics cards (support for CrossFireX and SLI configurations), a single PCIe 3.0 x4 slot, and three PCIe 3.0 x1 slots.

Storage subsystem might be organized due to six SATA III ports (bandwidth – 6 Gb/sec), three SATA Express ports (bandwidth – up to 16 Gb/sec), and a couple of M.2 slots with bandwidth index up to 32 Gb/sec.

In addition, this …
