I have a customer who brought in thier computer, as it was not booting. Upon inspection, I quickly realized that the problem was with the power supply. A fuse in the power supply is blown, and the board in the power supply has been scorched.
I tried to find a power supply with the same peramaters as the old one. The old one was 120W, and the closest I can find is 150W.
I could probably find one elseware, but my company is very particular as to where they order parts from.
Does anyone knowif this will cause any problems?

The wattage rating is how much power you may safely draw out of the power supply without over stressing it. Therefore, a 150W is better than a 120W because at 120W you will draw less than the maximum rating. Just make sure that the connectors are correct, AT, ATX type etc.

Thank you! I have been working with hardware for a long time, but the power supply is usually the last thing to go on a computer, so I don't work with them often. My A+ Certification exam and study resources didn't cover this.
