Connecting 780 to PSU

[jimmyrickard]

Can anyone help me out with connecting my 780?
The 780 is 8 pins. I only have 7 pins from my PSU, which doesnt supply enough power to run the card. Inthe box were two cables though with 8 pins to connect. I tried using 4 pins from the PCI marked connection and the other using the cables out of the box but it still didn't work. Is there anyway I can my PSU to connect to this card (Seasonic 500W btw)
Here's some photos which might make a bit more sense:

Would really appreciate if someone could me out here, I've been tearing my hair out the last couple of days trying to get a new GPU up and running

Cheers!

It makes sense why. The recommended minimum for the 780 is 600w so your psu wont be enough.

Seasonic 500W semi modular? not enough 780 required 600w

 

[jimmyrickard]

The 290 said it needed 600w and it powered it fine. Does the 780 draw more power?
It's an M12II Seasonic 500w PSU. apparently it has enough juice to run this card according to some other threads

 

[ak47jar3d]

No, 290 draws more power just not that much more.

So is the PSU the issue then?

 

[ak47jar3d]

Yes. You will have to replace psu to use 780 (I prefer to use SeaSonic or XFX only).
