Rhetoric Camel > 'Any help on updating a Dell Dimension 9150 power supply would be greatly appreciated also.'

One should be very wary of any branded computer's power supply and power connectors. If its one of those Dells in the smaller cases, its likely that they use a non standard sized power supply. Worse is that the motherboards usually have really weird power connectors that are either not compatible with a normal power supply's connector, or when they connector does fit, the pin out isn't right (really dangerous, will probaly zap your whole computer).
