HP Recommended

I have a HP Z4 G4 Workstation and I want to upgrade the graphics card Asus TUF RTX 3070.

Asus specifies a power supply with 750 W minimum, which is installed in my PC.

 

The Asus card has 2x 8-pin power connectors, which I understand should be 150 W each.

The HP power supply only offers 2x 6-pin connectors, the power rating is unknown to me (other community forums suggest that any 6-pin connector offers 75 W only).

Is it possible to use two 6-pin to 8-pin adapters to power this graphics card?

Are there any reasonable upgrade options available for the HP power supply, also third party?

 

Any helpful advice would be very much appreciated.
