I sometimes buy pretty new (1-2yr old) premade computers from foreign exchange students at the end of a school year. They often sell them for the cost of just the GPU, sometimes lower. The number of garbage PSUs I’ve had to swap out is ridiculous. People buy like $3k+ computers and are content with $80 PSUs it’s amazing. I’ve had them pop on me after only a couple months use. Meanwhile the PSU in my current machine was a major purchase for me back in 2010 and thing still runs every upgrade I throw at it.
