Help graphic card wont work!

[exdear]

i recently brought a power color radeon hd6950 graphic card. when i installed it to my pc, my pc cannot boots. All the fans was spinning but very slow. Then i use another power supply just power up the gpu. Before power up the gpu my pc can operate normally, but when i turn it on, all the fans become slower and my pc was turn off. Why? still not enought power? gpu problem?

 

my psus are corsair vs550 and avf 650w,

the HD6950 draws a lot of power

 

both PSU you have used are not made to support the GPU power

 

what happens if you dont use the GPU?

 

will your PC boot up?

Probably low voltage output from the wall socket. It's just a hunch tho. Are you sure you connected the pins properly?

then i think i found your problem\

 

you either dont use your PC with the GPU

 

 

or get a better PSU

 

go for at least Bronze rating PSU like Corsair CX500 or CX600 as the minimum

 

or EVGA 500B or 600B
