GPU ATI R9 280X 6pin boot

[degopokerpro]

All of the sudden I have problems with my GPU ATI R9 280X. I get no signal on my monitor. I have tried all sort of things with it and I have found out that when I connect the 6 pin connector it doesn't even boot with my onboard GPU. So the man problem is the 6 pin connector, I have tried with another PSU and it's the same thing.

Any ideas?

What have you tried?

Can you mention the make and model of your PSU and it's age? Better yet list your specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
