DELL Precision T3610 in connection with GPU RTX 3080

Hello Community,

I have the above DELL workstation. Now I want to buy a new graphics card (PNY GeForce RTX 3080 xlr8). The power supply with 685 watts (think 1 x 6 pin power supply) is currently installed. I have now read that a 750 watt power supply with 2 x 8 pin power supply must be available. My question is there such a power supply suitable for the T3610? Or are there alternative power supplies that are sufficient and fit in the box?

Thank you for your answers.

greetings

MF
