I had a pretty light duty discrete GPU 100 watts along with a Sandy Bridge i3 on this power supply. Should have been fine... The PSU gave up at 6 months... well it would if you played any common DVD file or BD MKV.. Worked fine for the first 6 months. I would not recommend it for anything but integrated graphics. The machine I am typing on is in that case. I just swapped the factory PSU out for an Green Antec EA-380. The connectors for the case fan are two pin.
