I want to know why people stay away from certain PSU product lines, like Corsair's CX. I know they are made with low-quality components, but power supplies can't just simply stop working for no reason.. What causes entry level power supplies to fail? High voltages? Overheating?
Good ones rare tested before being packed. But then they fail from aging which is accelerated from high temperatures. Poor quality/cheap components age quicker.
When this happens the power supply fails to regulate the output voltages within tight limits. I just saw a guy with 12V voltage at 14V - and his CPU at 206C because of it.
The people that test power supplies take these units to their upper limits and of course being enthusiast, we wouldn't want products that aren't at the top of their game. Truth is I would be comfortable using something like a corsair CX series for a low to mid range gaming system provided the price was right of course.
