MSI GT 1030 2GH LP OC version has faster GDDR5 memory, 1x HDMI version 2.0b, 1x DisplayPort version 1.4, max resolution is 4096 x 2160 @ 60 Hz, low profile design and low power consumption up to 30W. It can be installed on a pc with 300W psu. There is no need to replace the power supply with a more powerful one. Power supply comes from mobo (no 6pin power socket). PSU with 6pin cable is not required. My older computer has HDMI v1.4 and max resolution 1920x1080 so I needed a graphics card to connect pc to my new 4K tv. I did not want to add another source of noise, another fan, so I chose passive cooling. I think I found a card with the biggest heatsink in low profile version plus renowned brand. I'm happy with this card I would buy it again. It revived my pc allows me to watch 4k videos without stuttering. Overall experience of using windows is better as well. The most important thing it saves my eyes. Scaled 1080p picture is still not that crisp like native 4k resolution.
