Tower Plus EBT2250, PSU change need adapter

Hello,

I had to get a new 1000w psu for my EBT2250 that has a rtx 5060 in it from Dell under warranty because the original psu failed. The rtx 5060 has a 12 pin mini port and the new psu has standard 8 pin  because Dell upgraded the design of the psu due to issues with the original design of the psu that had 12 pins on it for the gpu. Dell support doesn’t have an answer on when they will have the 8 pin to 12 pin mini adapter they said. Does anyone have any ideas on where to get one? All the ones I see say for the 30 series, I cannot find one for the 50 series or even the 40 series. 

thanks in advance.
