This was setup for ATX power supplies and this is the signal they need to operate. (PS_ON#, green wire) which must be driven low to switch power supply on.
By what you have said, I would think you need a 4.7K pull-up resister.
And this is what you need
/**
* Select your power supply here. Use 0 if you haven't connected the PS_ON_PIN
*
* 0 = No Power Switch
* 1 = ATX
* 2 = X-Box 360 203Watts (the blue wire connected to PS_ON and the red wire to VCC)
*
* :{ 0:'No power switch', 1:'ATX', 2:'X-Box 360' }
*/
#define POWER_SUPPLY 2
#if (POWER_SUPPLY == 1) // 1 = ATX
#define PS_ON_AWAKE LOW
#define PS_ON_ASLEEP HIGH
#elif (POWER_SUPPLY == 2) // 2 = X-Box 360 203W
#define PS_ON_AWAKE HIGH
#define PS_ON_ASLEEP LOW
#endif

PS_ON is an open-drain output. So you need to connect the SSR positive control terminal to either +3.3 or +5V from the expansion connector, and the negative control terminal to the PS_ON pin.

Thanks David,
Are you suggesting this?
