Need a preamp if you have more than one source. You also need some way to control the volume, if there is no volume control on your power amp.

Why do people buy preamps if they can directly connect amp to stereo source/phone/PC/tv?
The purpose of preamp as I know it is to boost the signal to make it stronger. But I have never used preamps and my current system is already too loud (and sounds great) at moderate volume without preamp. Why do I see many people buying preamps even though they have powerful power amps?
