Which pci plug for gpu?

On my AX650 I use 1 PCI-E cable (from the PSU) and I connected the 8 pin (6+2) and the 6 pin (6 only)

I believe you have a second PCI-E GPU cable in case you do SLI or Crossfire.
 
Ideally, you want two leads from the PSU, one to each socket. You can however, run a single cable from the PSU if it has two plugs on the end with the required pin config.
 
use a 6+2 pin plug for the 8 pin socket, use either the 6 pin, or other 6+2 pin plug for the 6 pin socket, it makes no difference how many cables u use or whatever, they wouldn't put 2 plugs on one wire if it wasn't designed to run like that.
 
Ok so just run the one lead from the psu, this lead splits into two, as explained,

On a side note, what's the better option running the extra fans off a molex or direct from the mb, these are only 3 pin fans so won't be getting a signal for speed?
 
mine has 2 connections on the 1 wire and works great,like said it wouldn't be designed like that if wasn't safe to use :)

3 pin header on motherboard will (should) control the fan via voltage, so the better option. melex will run it at 100% at all times.
 
I used to power my old OC'd 290X with the one lead from my PSU that had the 6pin and 6+2 pin on it, had no problems at all :)

Right just switched it on, No signal ??
Fans are spinning on the gpu and the msi light on the side is on,

Here's what I don't before I installed the gpu,
Upgraded my main drive to a bigger ssd, installed Windows 10 on it and a few other programs,
I've just put the gpu in and plugged my hdmi cable in the gpu switched on and I'm getting no signal, as I said all the fans are spinning and the light is working on the side (white)

Any ideas, think I've got the most resent bios on my Mb.
I know there's nothing wrong with the pci slot as before swapping out my old ssd I took out my old Radeon hd gpu which worked fine.

3570k. When I installed Windows 10 I was using the hdmi socket from the mb as I had already taken out my old gpu, wanted to make sure I didn't have any conflicts with drivers!
 
I plugged the hdmi lead into the motherboard, and still no signal, mind you the card was still connected. Tried this before I posted?

Not even getting the boot screen, should have maybe added that in my first post
 
When switching back to the onboard from your previous card, before trying your new one, did you have to enable the onboard in your BIOS ?

I took out my old ssd and old gpu , then I put a brand new larger ssd in, installed Windows 10 and a few other programs back on, then after doing this I put the new gpu in this is where I hit a wall

What GPU are you using? It sounds like you may need a bios update, unless it's worked on that system previously?

EDIT

I just re-read the thread title... please confirm what leads you have plugged into your new gpu.

Lol I know the thread is a bit over the place think I'm confusing people where I've carried on using it for a second question..
Thought I should have started a fresh one,
I'm using a single 6 pin pci that splits into 2 leads with 6+2 On each end,
