More specifically, it supports SFX and SFX-L power supplies and graphics cards up to 12. Higher-end Nvida FE cards should also fit, but then you're going to need a larger SFX-L power supply, and I don't feel great about all that heat-generating hardware going into a cramped case with, at best, a single intake fan. There is room for SFX PSUs (I used a 550W EVGA SFX model) or longer SFX-L models, and if you don't need the maximum space for your GPU on the other side of the spine, you can add spacers to facilitate extra airflow behind the PSU and graphics card
