Just for the AMD GPU fanboys out there here are some early reviews of AMD's new top of the line video cards (yes they are water cooled) to enjoy. http://www.anandtech.com/show/7930/the-amd-radeon-r9-295x2-review http://www.legionhardware.com/articles_pages/amd_radeon_r9_295x2,1.html http://techreport.com/review/26279/amd-radeon-r9-295-x2-graphics-card-reviewed http://www.tomshardware.com/reviews/radeon-r9-295x2-review-benchmark-performance,3799.html Cheers. |

The big question remains unsolved, how much power this babies will realy use and from what source? And as they explain, what is the hardware who could support them. Sure not an easy task to handle the 500W of heat, now imagine a big cruncher with 2 of them. Let´s see in some days. |

Sure not an easy task to handle the 500W of heat, now imagine a big cruncher with 2 of them. Let´s see in some days. Juan, Tom's Hardware has equipment that measures the power draw from both the PCI-e socket and PCI-e connectors. http://www.tomshardware.com/reviews/radeon-r9-295x2-review-benchmark-performance,3799-12.html Still 1 card will need a pretty decent PSU, running 2 will need a bloody huge PSU (and case to take that 2nd radiator). Running more and you'll need to go to a custom case or barebones with a 2nd PSU (or hack the cooling system), but I can see some currency miners going all out with them. Cheers. |

Yes i know but they talk about: The Radeon R9 295X2 draws a total of 420 W from the auxiliary power connectors, and only a few watts more from the motherboard's PCI Express slot. What i´m curious to know how they manage to do that, since it uses 2x8pin connectors who has the nominal capacity of 150W each... On other point most of their measures are made for gaming, now crunching you know it´s another world. |

Yes i know but they talk about: Just because there is a spec doesn't mean they have to adhere to it. Sometimes these changes become the new spec. Some power supply manufactures will built their equipment with more overhead that is required. To the order of 50%, or better, & are able to deliver 225w+ per 8-pin connector.

I´m ansious to see what will happening with them working 24/7 at full load after a year or two. Seriusly i work in industrial high temperature and hard enviroment so we are allways looking for better quality products, better PSU´s and power connectors are allways welcomed. Sure i´m not thinking to use one of this GPU´s on the industrial area of course. |

I wish I could find that pic of the guy standing over and beating a dead horse, as it relates to what the g/card companies are doing with 28nm. Come out with the 20nm products already and the talk of $1500+ g/cards and 1500W+ PSUs becomes almost irrelevant I would imagine...just my thoughts. |
