[c-nsp] Cat6500 power supplies mixing

Hello,

Does anyone have an experience in mixing power supplies with different 
wattage in WS-C6509? According to this document: 
http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/configuration/guide/pwr_envr.html
power supplies with different wattage will not work in redundant mode:
"The system does not allow you to operate a power supply of different 
wattage even if the wattage is higher than the installed supply. The 
inserted supply shuts down."

The question is: with redundancy disabled (with different wattage power 
supplies), if one of the power supplies goes down, will the modules 
powered by this supply go down (even for a small time)? The power of the 
lower-wattage supply is enough for the whole system.

Sergey
