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 …

Palit to Release GTX 780 JetStream 6 GB Graphics Card in a Few Days

Palit has officially claimed that a long-awaited kick-off of GeForce GTX 780 JetStream graphics card with 6 GB memory will take place in mid-April. The model is differentiated not only the doubled video memory capacity, but also by the incorporation of an offbeat three-slot cooling system and factory overclocking. The privileges offered by the card will be available for the customers with about €600 in their pockets.

Palit GeForce GTX 780 JetStream 6 GB is based on GK110-300-A1 GPU with 2304 CUDA cores, 48 ROPs, and 192 TMUs. The core operates at the basic 902 MHz frequency, still it might be overclocked to 954 MHz level. The implemented GDDR5 modules employ 384-bit bus and run at an effective 6 GHz frequency (1.5 GHz nominal index).

Power supply is delivered through one 8-pin socket and one 6-pin socket. The estimated TDP level makes up 250 W. Video connectivity is realized by means of four dedicated ports: HDMI 1.4a, DisplayPort 1.2, DL DVI-I, DL DVI-D. In addition, …

SilverStone Comes up with Grandia GD10 HTPC Case

All devotees of full-scale systems might now revel in an opportunity to ‘locate’ ATX-motherboards into a small-sized elegant enclosure. SilverStone is glad to introduce a new HTPC case with horizontal orientation – the Grandia GD10. It is predestined not only for CEB and micro-ATX boards, but also for standard ATX models with the maximum of 8 expansion slots; that should become a major advantage of the new-comer.

SilverStone Grandia GD10 features 442x171x362 mm dimensions and draws attention by a stylish, compact design. The layout allows for creating diverse system configurations with multiple unique elements. Therein, the case accommodates a single slot for 5.25-inch drives that might be converted, if necessary, into a bay for a single 3.5-inch drive or two 2.5-inch drives. Additionally, there are two separate 3.5-inch bays and one 2.5-inch bay for hard drives.

Internal spacing is estimated for the graphics cards with the ultimate length of 309.88 mm and for the …
