that looks like a prebuild system PSU

 

it only used to power the mobo

 

do not use them for powering other parts

What is your power-supply?

Is this a Prebuilt system? (if so what brand and model?)

It's an old hp xw8400 workstation, that connecter was never used for anything, it's been just hanging there like that, i didn't modify it in any way.

 

The power supply is a delta electronics 800w one, can't tell the exact model right now cause iàm at work

NO. DO NOT use that power connector for GPU. What you need 2 molex to dual 6 pin PCI-e adapters like:

and if you needed 8 pin power, you'd need a 6 pin PCI-e to 8 pin PCI-e like:

Thank you, I have available two 6pin connecter, and my graphics cards needs a 6pin and an 8pin, I am currently using an adapter from one of the 6pin to 8pin, but that gives only 75w, and the card need 100w on the 8pin connector (uses 250w in total). It works, but I can't do any overclocking like this. I was hoping I could get more  power from that 10pin connecter.

 

Would daisy chaining the 8 pin that goes in the mother board to the graphics card help?

 

Thank you again for the answer.

Likely not. never mess with the 8 pin (assuming you mean 2x4 pin CPU) power. NEVER split the 8 pin to power 2 CPUs at the same time. If you have 2 separate PCI-e power leads running from the PSU, which I very much doubt you do, then adapt away for a total of 4 PCI-e 8 pin power leads. Also, if you have a spare 8 pin, it is for a 2nd CPU. You can go above the 75 watt limit (as carried over PCI-e bus) by using the molex to PCI-e adapters I mentioned.
