4.2.6 Capacitive Load – RECOMMENDED
The power supply should be able to power up and operate within the regulation limits
defined in Table 4-2
, with the following capacitances simultaneously present on the
DC outputs. These Capacitive Loads are to simulate what a motherboard / system
provides when connected to a power supply.
