HD 6850 is giving me some problems

[Pandorox]

So I've been waiting to get my PSU in just so I can run this card & it finally gets here but with some problems.

My computer trys to boot up then it fails. The screen doesn't even turn on (just goes straight to no signal).

Here is the PSU I bought http://www.newegg.com/Product/Produc...82E16817139027

Here is the GPU http://www.newegg.com/Product/Produc...82E16814102908

Not sure what else matters. Running 2 120mm fans & an 80mm ontop of the CPU cooler of course.

Also I have a USB3.0 adapter card that uses a 4pin.

Need to figure out if I need a bigger PSU or whatnot.

Is everything plugged in properly? Check all the connectors are flush with the edge of the socket, there should be no gaps. Have you got the two 6pin PCI-E connectors plugged in to the GPU?

[Pandorox]

There is only 1 PCI-E connector for the GPU.

But I keep thinking that if it's my PSU overloading wouldn't it crash my comp. Also everything seems to be taking a little longer to open up & run properly since I installed the GPU & PSU.

Not to necro a thread or anything but I ended up finding the problem. My Bios were outdated & were causing boot up problems. Nothing with my PSU actually.
