Answer :
The minimum voltage levels required for compliance on the +12V rail, +5V rail, and 3.3V rail can vary depending on the specific power supply unit (PSU) and its intended use.
These levels are often specified by industry standards and regulations.
To find out the minimum voltage levels required for compliance, you can refer to the specifications provided by the PSU manufacturer or consult relevant industry standards such as the ATX (Advanced Technology eXtended) standard.
For example, according to the ATX standard, the minimum voltage levels for compliance are as follows:
+12V rail: The minimum voltage level required for compliance on the +12V rail is typically around 11.4V. This means that if the voltage on the +12V rail drops below 11.4V, the PSU may be considered non-compliant and could potentially shut down.
+5V rail: The minimum voltage level required for compliance on the +5V rail is typically around 4.75V. Similar to the +12V rail, if the voltage on the +5V rail drops below 4.75V, the PSU may be considered non-compliant and could shut down.
3.3V rail: The minimum voltage level required for compliance on the 3.3V rail is typically around 3.135V. If the voltage on the 3.3V rail falls below this level, the PSU may be considered non-compliant and may shut down.
It's important to note that these values can vary depending on the specific standards and regulations applicable to the PSU you are using or researching. It is always recommended to consult the PSU manufacturer's specifications or relevant industry standards for the most accurate and up-to-date information.
The minimum voltage levels required for compliance on the +12V rail, +5V rail, and 3.3V rail can vary depending on the PSU and industry standards. It's best to refer to the PSU manufacturer's specifications or relevant industry standards, such as the ATX standard, for accurate information. Remember that these values are subject to change and may differ between different PSUs.
