Theoratically, can i install 6 GPUs in HP Z820 in given 7 PCI slots ?

Hello,

Theoretically, if hardware limitation put aside (obviously No space in HPZ820 chassis) can we populate 6 PCIe lanes with 06  GTX1660Super cards with mini risers? Just a thought to use this machine in ethereum mining.

My system:

HpZ820 dual E5-2687W processors, 64gig, 1125W power supply

sysboard 158b 1.01

PCIe3 x16, qty 3 (qty 2 when optional 2nd CPU is not installed)
NOTE:
3rd PCIe x16 slot is ONLY available when 2nd CPU is installed. This is Slot #4 on the system board and is
designated by a white-colored PCIe connector.

well i have tried this on Hp Proliant ML350 gen 08.. All cards recognized, but power supply is not supporting my goal.. I shall try my luck with another PSU 1300W (along with its native 400W X 02= 800W). Will see the results then... As you can see in the pic, i tried with 750W but system gets crashed and reboot...
