PCI-express power problem
Greeting I have been trying to troubleshoot a discoloration on the screen with my new-built computer. The whole screen is tinged with red, and at first I got the message that the GPU doesn't have enough power.
I had connected the PSU to a slot on the motherboard that gives the PCI-express slots more power.
Then I later realized that aside from connecting the PSU to a PCI-express power slot on the mobo, I was supposed to connect the PSU directly to the GPU. Something I had failed to see before.
The GPU power connector has a 6-pin male connector, and the PSU a 6-pin female for PCI-express. But it doesn't fit very well onto the GPU, I had a great deal of trouble connecting the two.
And then later I found that included with the GPU was a cable with two 3-pin male molex connectors (but with the size of four, just that the left pin is missing on each), and on the other end one 6-pin female (though it is missing one of the metal connectors in the lower middle female.) Anyway, this 6-pin female fits perfectly into the GPU power slot, and then I connect the other two ends to two 12 v 4-pin molex connectors from the PSU.
When I start the computer now, the screen is still tinged with red, but I don't get the message that the GPU has insufficient power anymore.
I have drawn the conclusion that the GPU has been adjusted to the low-performance mode, so that ut doesn't understand that it has got sufficient power supplied to it now. I guess this can be solved by somehow resetting the GPU? What do you guys think? Maybe the card recognizes that it is connected to the PSU, but that the cables/connections are wrong, so that it doesn't get the power it needs, even if there is no dialogue box about it when I start my computer, so that the screen is still tinged with red.
I have uninstalled the GPU, shut down the computer, reset CMOS and removed the card, and then installed everything again, but I still get the red color.
Also, aside from the direct 2x12v connection to the GPU there is also a slot on the mobo that is 12 v for PCI-express slots. The manual says that it is optional but recommended to supply power to that too. Do I really need to connect all these four 12 v molex connectors to my motherboard? It seems a bit overkill
Whew, tough nut to crack, hope you guys can help me out!
