I purchased a powercolor pcs+ 6870 for my computer because based on reviews, the card is supposed to be basically silent at idle, and barely any louder under load. I installed the card in my computer, turned it on, and the sound coming from it is definitely not quiet. It almost sounded to me like the card was running at full speed, but running a few benchmarks the fan spun up noticeably faster/louder so it's definitely not running full speed.
I tried pulling one of the 6 pin power connectors and booting the computer, it started but I got no image from the card. However the fan was spinning, and was, like it was supposed to be, almost silent. I'm asking if it could be the power supply because I am running only a 460 watt supply which is lower than recommended. System runs completely stable though, I ran MSI Kombustor and Prime 95 at the same time for about 30 minutes without a problem.
