The typical voltages supplied are: 3.3 volts 5 volts 12 volts Power Supplies The 3.3- and 5-volts are typically used by digital circuits, while the 12-volt is used to run motors in disk drives and fans. Power Supplies The main specification of a power supply is in watts. A watt is the product of the voltage in volts and the current in amperes or amps Common Wattages Needed PC Item Watts Accelerated Graphics Port (AGP) card 20 to 30W Peripheral Component Interconnect (PCI) card 5W small computer system interface (SCSI) PCI card 20 to 25W floppy disk drive 5W network interface card 4W 50X CD-ROM drive 10 to 25W RAM 10W per 128M 5200 RPM Intelligent Drive Electronics (IDE) hard disk drive 5 to 11W 7200 RPM IDE hard disk drive 5 to 15W Motherboard (without CPU or RAM) 20 to 30W 550 MHz Pentium III 30W 733 MHz Pentium III 23.5W 300 MHz Celeron 18W 600 MHz Athlon 45W Common Wattages 180 watt 200 watt 250 watt 300 watt 350 watt 400 watt 500 watt 600 watt Common Wattages A 400-watt power supply will not necessarily use more power than a 250-watt supply. A larger supply may be needed if you use every available slot on the motherboard or every available drive bay in the personal computer case.
