Basically, the article explains how the r9 295x2 needs a good psu or there will be problems(which makes perfect sense). The psu they used for their experiment is a be quiet! Power Zone 1000w with dual 295x2's in crossfire. Based on " the better design of its PCIe power connectors" and "Its capacitors (which) are better able to deal with the AMD Radeon graphics card’s peaks in power consumption" as a conclusion from the article: I think it's a good buy. Especially, since this was tested in a 30C room and "there are no failures to report".
This psu also is 20% off on Newegg(150$) until the 21st which has convinced me to get it.
I plan at some point to add another gpu to my build although not a 295x2 as well as more ram(depending on the money supply). Like to know peoples opinions.
