I have recently purhased a Radeon H7950;and foolishly believed that my PSU would e up to the job.
It appears hower, that the card requires 1 6pin PCIE and 1 8pin PCIE. My PSU does not have the 8pin connection.
So I decided in my infinite wisdom (after looking around a little), that it would be okay to just connect both of my 6pins.
Now it appears as if the card is turning on, but producing no output.
I'm concerned that I may have broken it. However, I don't know if this is normal behaviour or not?
If I need to, I can replace the PSU (if so, can you give <= £100 PSU recommendations?); however, only if it is definitely just by design that there is no GPU output?
Please give me as much information as possible; I'm quite desperate to solve this.
The 2900XT was the only card I know of that didn't NEED the 8pin plug. If you plugged in a 6pin plug where the 8 should go it would run, but not allow OCing. I've never heard of any other card that had an 8 but would run with a 6. Your card does what ever other card does when not receiving the power it wants. It flat doesn't run.
