power supply electricity usage rates

As a computer technician, I buy what I think are AT and ATX power supplies that have "enough" wattage to handle most userss computers -- usually I get 250 - 350 watt units in case I need one for a customer.

Question is, if I put a 350 Watt power supply into a computer that was using a 170 Watt supply before it broke, will it use more power?  The obvious answer seems "yes", but, I know the computer only uses a small bit of the power coming into the system...anyone with electricity background probably knows the answer offhandedly.  An answer with a little information would be nice.  Thanks a lot.

Putting a higher power-rated supply in place of a lower-rated supply does not mean it's going to use more electricity.  The ratings are for how much total wattage the supply is capable of putting out without dying or losing regulation on the voltage rails.  A higher-rated supply will be able to handle larger loads when they happen; it doesn't mean they will use more power.
