I just bought a Lenovo H430 with the following specs:
1TB 7200rpm HDD
Intel GMA HD
The PSU is 280W and I wanted to upgrade the graphics card. I will not be gaming and will only be using it for movies (e.g. .mkv files 10-30GB in size). What is a decent graphics card I could upgrade to without having to purchase a PSU? I'm fairly certain that the PSU is un-upgradeable because it is built into the system.
