I bought a FSP Aurum 600w today. I finally replaced my generic power supply after using it for 2 years. Now, I just want to know how can I test if my PSU is good? I mean, I left my PC downloading something but when I came home, it hung again. I thought changing the power supply would fix the problem. I also changed my RAM sticks to RipJaws which went okay. The BSODs were gone. Now I just need to solve the unnecessary hanging when I leave it overnight while downloading.
