I could have sworn I just posted a thread but it doesn't show and I basically need help with a HD 6870 that does not display when connected with an HDMI to my flat screen. The old card works fine and the desktop I have is only a week old (not that that matters) but it is a decent unit with amd 6 core and it came with a 7570 card but I was going to bump up my gpu but it does not for some reason display. Could it be the 460w psu? should it not run just plugged into the pci-e? i have one extra 6 pin at 18.5 amps but I plugged it in and nothing changed. am I underpowered or should it work atleast give me a screen to be able to troubleshoot? Sapphire has been very sparse with support...send em and email we'll get back to ya....no phone numbers to atleast talk it over...called amd from a number in the manual and the rep/agent thinks its my psu which btw says nothing of extra power hook ups...the new card does have two 6 pin females does it require two connectors plus the pci-e slot?
