There is always a chance the PSU will go bad. I have not had the first one to stop working and take out the motherboard; etc. There is the first time, however. My Compaq is running a 250 watt PSU since day one and without a problem. Should consider myself to be fortunate, however. I think was I was being swayed by the SSD because I have been thinking of installing one in he Compaq and then cloning my HDD to the SSD.
