ATX Power Supplies

ATX power supplies come with standard requirements that have shifted over the years, in accordance with the change in ISA bus usage. Originally, a requirement was put in for a −5V output, which matched the ISA bus; however, modern PCs no longer use the ISA bus, so the requirements are for +3.3V, +12V and +5V. There is also a requirement for a low-power supply of −12V and for a 5V supply, which is used for standby mode. Understanding these requirements is necessary when determining which ATX power supplies to purchase based on the age and design of the unit in question.

Other important specifications include the input voltage, the maximum power capacity (e.g. 350 Watts) and the input frequency range. If you have any questions about these things or the differences between an ATX power supply and a server power supply, please get in touch with us at eSAITECH and we can help you find the supply that will work perfectly with your machine, offering original equipment, refurbished options and new-in-box (NIB) supplies.
