Will a larger wattage power supply blow up my computer?, Odd but tricky question... Options

[tomazws]

So, this customer have a dead 150W power supply and would like a replacement. The thing is right now it's really hard to find a 150W power supply, so I suggest him to upgrade to a 250W, 300W, 350W whatever... but then he asked "Will it blow up my computer? What if it fried my computer? Is your company gonna take full responsibility?"

How would you explain the extra 200, 300W won't fry his stupid thing?!?!??!??

Geez I feel so dumb..

It's wattage that's important. Of course, it's about QUALITY wattage...
I don't cheap out on my power supplies since it's one of those components that can really screw up your system if you get a crappy one. Stick with one of the brand names; Antec/Enermax/Thermaltake/OCZ/FSP.

I'm sure you know your stuff if you're selling them, but make sure the 150W isn't from some propritary case like a Dell, Shuttle, or similar. Those require their own power supplies (plugs and sizes are different).
