A PC, in most cases, does not need an amplifier. Amplifiers are typically used to boost the signals from low-voltage audio equipment, such as smartphones, tablets, and analog turntables, to a level that a speaker system can handle. Computer sound cards and built-in amplifiers in speakers or external sound cards provide adequate amplification for the majority of computer users. However, if you are connecting low-voltage audio equipment to your PC, you might need a USB or other type of amplifier.
