Product: HP Z6 G4 Workstation

Dears,

Is there an official HP part for powering a second GPU that uses two 8-pin PCIe power connectors when the supplied connectors are already in use? I currently have an RTX 3080 FE in the machine and I'm thinking of putting in another or an RTX 2080.

If no connector, then should I hack in a second power supply or use a molex/sata power adapter?

The workload will be inference, not gaming.

installing a second high performance video card like the rtx 280

 

will most likely overload the systems GPU subsection of the power supply

 

even if using the 1000 watt power supply (L20514-001)

 

and cause damage to the power supply or system

 

depending on what else is installed

 

such as dual cpu number of ram dimm's Hard drives installed cards

Oops. I realize I forgot to specify what the machine has eaten. 2x32GB RAM, 2xNVMe drive, 1xCPU of 85W TDP.
