Whatever happened to people who tried to run high power consumption graphics cards or multiple GPUs without external power? I want to make a list of reports from people who have either ran them for a long time without problem, people who did damage their equipment and people who only experienced shut downs. Take for example the following reviewer who is running two cards off a splitter. The Radeon 5870 requires 188w while the GeForce GTX 285 requires 205w. Any reports if he carried on successfully? http://arstechnica.com/apple/2010/10/tri-screen-cpu-monitor-ars-reviews-the-12-core-2010-mac-pro/2/ Please try to avoid arguments about what is and isn't possible. Those debates have been done to death. Let's just gather data in a scientific manner now that enough time has past to adequately make a metadata analysis.
