Depends on how you look at it and which graphics card you got.
Lets say your running on a core2duo machine, you have a GTX280, 4gbs of ram and one sata hdd.
Based on your system needs, if the system is power effiencent you won't expect much problems except for the psu wearing out within 6 months or so.
If your system was power hungry and needed the juice, yes your asking for problems and something might short out.
Have a look at Antec,corsair and a few other psus from online stores and look at the customer reviews with good feedback rating by others.
That will pretty much give you a answer to what your looking, sometimes it can be the users fault by building stuff that won't work.
Other times, it can be the manufacturer, its 2 way deal on hardware issues if you look at everything closely.
