I have a workstation HP z800, i am confused about the PCI slots and the number of graphics card that can be connected..
i want to connect 4 graphic cards, my motherboard have the following slots:
1–PCIe2 x8(4) 25W
2–PCIe2 x16 75W
3–PCIe x8(4) 25W
4–PCIe2 x16(8) 25W
5–PCIe2 x16 75W
6–PCI 32/33 25W
7–PCIe x16(8) 25W

My Z800 Spec:
x2 Intel Xeon X5670
64 GB RAM
X2 SAS
X6 HDD
***Power Supply with maximum output = 850 W

so the question here, can i connect 4 Graphic Cards (Gigabyte G1 Gamming - Radeon RX480/ 8GB GDDR5)?
and if i can connect just 2, is there someway to connect the other 2 (some kind of connectors?)

And will be the power supply sufficient?
If not, is there a way to add another power supply (without having to replace the one i am using) to maybe work in parallel?!

>Hint: there will be much power consumption as it will be used for mining, i don't mind to use some kind of connectors and to open the Case.. i just need it to work!
