Over and over again I've seen those junk PSU fail. The user is lucky when it simply won't POST a system but more often it just frys a hard drive or motherboard. You've had a PSU running for two weeks and you are convinced it's "OK"? Take a car and redline it, it too will run a while.
The problem is not total wattage most often, rather the particular rail most demanding on a particular system. The major problem there is that these generic PSU aren't worth their rated wattage and/or not clean power. They may CLAIM 300W but that doesn't mean they can deliver 200W with much stability. IMHO, it's fraud how they're labeled. Show us generics that are rated accurately and can sustain clean output over a period of time (over a year of run-time) and we may have a better picture of viability.
Just to chime in, I have and continue to use both "quality" and "generic" PSUs. My only real observation is that the name-brand, quality PSUs weigh more.
For real, if you're doing serious overclocking, you're going to want a good PSU with a higher efficiency and stable rails. This said, I've severely overclocked an AMD mobile 2500+ on a $7 Powmax 9900D PSU without a problem. But in the long term, having an Enermax, Antec, etc. is probably a good idea.
