PCI Express 8x max power

[verybigfurrymonster]

Hi,
I have a server motherboard with a physical 8x PCI express slot.
I put a gtx 970 and it s working fine in windows. I haven't tried gaming though.
The gtx has an extra 6pin power that I m providing.
I m wondering if the 8x pci express slot can provide 75 W like a normal 16x pci express or if it s limited to 25W.
The 8x slot is really tiny so I m wondering if the power that can be drawn is smaller than a 16 x slot.
Thanks!

I assume it is a physical x16 slot and only a x8 interface. It will still provide the same power as an x16 since it is x16 physically.

It s a physical 8x slot, it s about half the lengh of a usual 16x slot.

It should still have the same power. Look at the pin-out -- https://en.wikipedia.org/wiki/PCI_Express#Pinout All the power pins are on the first few pins. That means that every slot is the same.

Thanks, that would make sense.
