The issue i am having is that im not getting any signal from the graphics card. The monitor seems to sense its there, but then reverts to the no signal screen. The integrated graphics works fine. Im using it via the mini hdmi connector (waiting on dvi connector to test). I bought the card 2nd hand and was assured that it was working, although they said they only used the dvi ports.
After a few hours of scraching the head and reading forums i decided to replace one of the psu's 8pin to 6pin cables for the 6pin to 2xmolex and connected it to a 2xmolex to 6pin lead and into the card. It worked and i saw the post screen and got into the bios fine. Next time i turned it on it wouldnt work and im back to square one. So swapped it back to the two 8pin to 6+2 pin cables to try and nothing.
Ive tried the card in all the pci-e slots and no go.
Would this be a symptom of a weak PSU? I wouldve thought that a 550w would be ample, but i have read the GTX465 are power hungry and i dont really know how good a the Powercool is.
Any advice would be great before i go shelling out on a new mb, card or psu.
550W PSU from a reputable brand (Antec, Corsair, SeaSonic, XFX, etc) would be enough, but I don't think many people place too much faith in a Powercool PSU. Try a different PSU, maybe something like this:
