#183133 - PSU allowed to do +/- 10% on 12V rail at max load
Responding to: ???'s previous message
The PSU is allowed +/- 5% for all positive voltages, and +/- 10% for negative voltages.

But the +12V out is allowed to drop down to +/- 10% regulation at peak 12V load.

The requirements are covered by the ATX standard. At least the first link is not a current version (the latest PSU standard is ATX12V 2.3):
