Here is the information from APC's FAQlist:

Surge protectors filter the power for surges and offer EMI/RFI filtering
but do not efficiently distribute the power, meaning that some equipment
may be deprived of the necessary amperage it requires to run properly –
causing your attached equipment (computer, monitor, etc) to shutdown or
reboot. If you need to supply additional receptacles on the output of your
UPS, we recommend using Power Distribution Units (PDU's). PDUs evenly
distribute the amperage among the outlets, while the UPS will filter the
power and provide surge protection. PDU’s use and distribute the available
amperage more efficiently, allowing your equipment to receive the best
available power to maintain operation.
