Rather than a long list of units that are good and bad i feel that new people here could often use a list of units that are so bad they arent even worthy door stops to keep them from getting absolute crap. There are always lists of recommended parts, but for people with limited selection thats not to helpful so i feel that a list of absolute crap to steer clear of would be more useful for them. If you have one you want added to the list post it with a link to a review where it really failed, its a bit late so i havent generated a full list yet but i have a few, im going to be sorting this by brand then model to help keep it a bit organized.
If you are looking for a PSU, look through your options, look at this list, and rule out any that are on this list, they may be cheap, but they will do their best to fail spectacularly, and its not worth the risk
