Standard atx psu outcome voltages

Some power supplies have a manual switch for selecting input voltage , while others automatically adapt to the mains voltage. Most modern desktop personal computer power supplies conform to the ATX specification, which includes form factor and voltage tolerances. It was the first major change in desktop computer enclosure, motherboard and power supply design in many years, improving standardization and . Plugging a power supply with an incompatible pinout into a motherboard that uses a standard pinout (or vice versa) usually in the destruction of.

In the context of ATX PSUs though, rail refers to each output that has a separate group of current-regulating circuits.

Motherboard Power Connectors. Every PC power supply has special connectors that attach to the motherboar giving power to the system processor, memory, and all slotted add-on boards (ISA, PCI, AGP). Attaching these connectors improperly can have a devastating effect on your PC , including burning . If a power supply is providing the parts of a computer with a particular voltage outside .
