Go to solution Solved by jaslion,

Sup the 6 pin cables on the z440 are actually carrying 150w total each. basically hp just made it so the users would need to buy their official adapter if they wish to do an after market upgrade or start with no gpu at all. Just to get some more money from em.

 

Just get a proper adapter like this and you are good to go. https://www.stonegroup.co.uk/hp-power-cable-8-pin-pcie-power-to-6-pin-pcie-power-8-9-cm-1tpowpac-012557/

 

Don't get cheap cruddy generics as those often use the WRONG thickness of wire that melts the connector due to the heat it creates by being overloaded/ having too much resistance.

 

Normally 6 pin to 8 pin is like a MASSIVE no go but here hp literally made weird stuff 😛

Hi there, 

 

I own Z440 HP workstation PC that I use as my media PC. Currently has GTX 1060 but want to up it to 1080 Ti. 

 

However, PSU is non standard and I am not able to swap the PSU.

 

PSU comes with two 6 pin PCIE power connectors. Strix requires two 8 pins.

 

Would it be okay for me to convert the 6 pins to 8 pins and run the card ot it isn't enough wattage?
