yeah, i dont know if epower is a good brand though. And i chose these two psu because they were modular. With my case i need optimal airflow. A LC17 HTPC case, but for high end gaming.
For high end gaming, you should really get at least an atx mid tower, ideally full tower. That HTPC just won't cut it even with modular psu. Those things are meant to be small and quiet, not cool.
EPower is not a bad brand, just an unknown. Reviews are good, and I'm pretty impressed after using it. Besides, the second on is OCZ, which is considered a good brand. If you don't mind the big mir, it's the best bang for the buck too.
