SilverStone OP800 [10/12] For workstation systems with high powered graphics cards an additional power connector to the baseboard may be needed this connector supplies additional 12v power for the higher power level graphics cards used in workstation applications connector housing 6 pin molex 45559 0002 or equivalent contacts molex 39 00 0207 or equivalent

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 3a for pc board circuit to operate 5

The efficiency is specified at 50 and 20 loading conditions to help reduce system power consumption at typical system loading conditions 5

The pson signal is required to remotely turn on off the power supply pson is an active low signal that turns on the 5v 3 v 12v and 12v power rails when this signal is not pulled low by the system or left open the outputs except the 5vsb and v bias turn off this signal is pulled to a standby voltage by a pull up resistor internal to the power supply 5

Protection 6

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 6

The power supply shall shut down in a latch off mode when the output voltage exceeds the over voltagelimit shown in table 4 6

The power supply shall shut down in a latch off mode when the output voltage is short circuit 6

This power supply shall have current limit to prevent the 5v 3 v 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 6
