Smart power switch- any options to reduce PSU idle power?


Recommended Posts

I have a 'smart power switch' that does not work consistently. The strip has a calibration feature; which I dialed to the point that it triggered the way I expected it to do so- this happens to be the "MAX" setting.


At first, the power stip didn't trigger at all- the USB devices also kept their power so I switched the "S4/S5" setting in the BIOS. That did the trick- the USB devices were no longer active.

The strip now triggers roughly 20% of the time I shutdown the system- leaving 80% of the time the TVs and my LED power supply switched on.


Did anyone have a similar problem? How to fix this? I am tempted to unplug the cabinet entirely as alternative and leave the PC on autoboot when power is available ("power on after power loss" BIOS option).

I wired in a sw at front bottom of cab in parrallel with the start switch on the PC. so it act the same as  a normal start switch on the PC. Then I took a spare ATX power from the PC power supply - 12v and use it them to fire 2 x Fuse protected AUTO  (Car Horn Relays) rated at 30A each. I did put a diode over the coils of the relays as well. The relays control the 12vdc and 5vdc to rest of the cab. So when I turn the PC on it in turn turns on the 12VDC and 5vDC. Cheap as to do.
