Question from Ana: I bought a new iMac from Best Buy a couple of years ago.

I also bought a surge suppressor to go with it because the salesman said it would prevent the computer from being damaged by lightning.

We had a thunderstorm last night and our power went off. It came back on a couple of hours later but now my TV, dishwasher and iMac are all dead. None of them will do anything when I turn them on.

My question is, do surge suppressors really work?

Q&A: Is it ok to replace a computer’s power supply with one of higher wattage?

Posted on October 25, 2019

Question from Debra F.: I need some advice in order to settle a disagreement between me and my boyfriend.

My computer stopped working and my boyfriend says he can fix it by replacing the power supply. He put the one out of his PC in there just to see if everything else still works, and it does.

The original (bad) power supply is rated at 350 watts but he wants to replace it with one that’s rated at at least 600 watts.

My question is will the extra wattage put out by a stronger power supply damage my computer? My boyfriend says it won’t but it seems to me like it would. Which one of us is right?

I’d also appreciate it if you could recommend a good brand that doesn’t cost a lot. Thanks in advance for your help.
