Cougar has recently introduced a new power-saving PSU series codenamed GX-S. The series includes three high-efficiency models which meet the requirements of 80Plus Gold standard: GX-S 400W, GX-S 500W and GX-S 600W. Cougar promises that the products will be available in free sale already in early April. All three PSUs are housed in a black casing with golden logo and accommodate high-quality Japanese capacitors that ensure utmost performance and reliability.



Cougar GX-S series employs LLC technologies which are called to reduce the power loss on Off/On activities. The models also feature a power-saving framework to comply with Eco-Friendly EuP, ErP Lot6 and Energy Star 5.0 standards. Hence, the units consume less than 0.9W in ‘Off’ mode. Besides, GX-S units absolutely meet ATX12V specifications, support all novel (and future!) platforms on the basis of multi-core processors, as well as several graphics adapters with PCI-e 2.0 interface and 8-pin PCI-e connectors.

Introduction



If you remember, we’ve already worked with the Bykski brand in the review of the FOUR series CPU water block. And I decided not to leave new Bykski FOUR Founders GTX 1080 withоut attention. Worth mentiоning that the FOUR sеries is cоlor-cооrdinated mаtch of fіttіngs, CPU wаter blоcks, and GPU water blоcks. Those, who have ever sееn Bykski prоducts, will no doubt recоgnize new wаter block. The sаme as the FOUR CPU blоck, it has a colоred mеtal top cоver оver an аcrylic top. Today, as you’ve already understood, we are going to speak about Bykski FOUR Founders GTX 1080. And as a usual, the first point of our review is packaging and contents.

The Bykski FOUR Founders GTX 1080 is already bought and must be delivered soon. When it is finally here, we can see a plain black cardboard box with an identifying sticker on the back. But the box is not so important, when inside of it you get something really stunning. …

Along with other AMD partners, PowerColor has elaborated its own version of Radeon R9 270 adapter. The PowerColor Radeon R9 270 OC is differentiated from rival products by an improved cooling system and factory overclocked frequencies. Its release is scheduled for late November and the retail price won’t hit over $180.



To begin with, this graphics card is naturally based on AMD Curacao Pro GPU, developed under 28 nm technological process. It consists of 1280 current processors, 32 ROPs and 64 TMUs. The core runs at 930 MHz frequency and is able to gain 955 MHz frequency on overclocking. The incorporation of GDDR5 memory (2 GB) with 256-bit bus interface ensures some striking bandwidth of 180 Gb/sec; this provides for the support of gaming applications with high resolution. Memory chip operates at 1400 MHz nominal frequency but might gain the index of 5600 MHz of effective frequency on overclocking.


Cooling system, implemented within Radeon R9 270 OC, cannot be called …
