Hi guys, this my first post to this community. I own Optiplex 3080 MT with i5-10505, 2x8GB DDR4, 256GB Nvme, 2x1TB 2.5" hdds and one Intel Wi-Fi 6 AX200 M2 card. The power supply is 260Watts. The question is will GeForce GT1030 fit without any power issues? The card itself is rated to be 30W max, but i am not sure if it will work. Help is highly appreciated
