Hello,

Your +12v rail should be within +/- 5% of the specified voltage of 12v

So around 11.4v to 12.6v as a rough guide.

You tend to find the voltage will droop under load conditions.

Only on a power supply that does not have Active PFC. Mine is rock steady under full load at 12.03v. On most PSUs I would consider .1v or less to be acceptable.
