3.8 Overshoot at Turn-on /Turn-off   
Any output overshoot at turn on shall be less than 10% of the nominal output value. Any overshoot shall 
recover to within regulation in less than 10ms. 
3.9 Efficiency 
The minimum power supply system efficiency shall be 
≥ 80% with maximum efficiency up to 87%, measured 
at nominal input voltage 115 V or 230 V and full loading. 
3.10 +5VSB (Standby) 
The +5VSB output is always on (+5V Standby) when AC power is applied and power switch is turned 
on. The 
+5VSB line is capable of delivering at a maximum of 3.0A for PC board circuit to operate. 
4. Protection 
Protection circuits inside the power supply shall cause only the power supply’s main outputs to shutdown. If 
the power supply latches off due to a protection circuit tripping, either a AC cycle OFF for 15 sec, or PSON# 
cycle HIGH for 1 sec must be able to restart the power supply. 
4.1 Over Current Protection 
This power supply shall have current limit to prevent the +5V, +3.3V, and +12V outputs from exceeding the 
values shown in table 14. The current limit shall not trip under maximum continuous load or peak loading as 
described in Table 5.    The power supply shall latch off if the current exceeds the limit. The latch shall be 
cleared by toggling the PSON# signal or by cycling the AC power. The power supply shall not be damaged 
from repeated power cycling in this condition. The –12V and +5VSB outputs shall be shorted circuit protected 
so that no damage can occur to the power supply.
