A power supply unit converts the alternating current sent to the home into direct current that can be used by a computer. There are several types of power supply units, depending on the voltage and current they can provide. A typical desktop PC often uses a power supply with a capacity of about 200W to 300W. When various expansion cards or OverDrive processors are added, power is consumed by those devices, so the power supply unit needs to have a capacity that matches the expansion. Although it is possible to purchase a power supply unit separately, power supplies are often sold built into the case.

家庭に送られる交流電流をコンピューターで利用可能な直流電流に変換するユニット。 この電源ユニットには、その電源が提供できる電圧や電流によっていくつかの種類がある。一般的なデスクトップタイプのPCでは、200W~300W程度の容量の電源が利用されることが多い。さまざまな拡張カードやOverDriveプロセッサーなどを拡張すると、それらのデバイスによって電力が消費されるので、電源ユニットには拡張に見合った能力を持つものが必要である。 電源ユニットを単独で購入することもできるが、電源ユニットはケースに組み込まれて販売されていることが多い。
