    I have the habit of turning off my psu everytime when I shut down my pc. It's mainly because the motherboard light are very annoying at night when I tried to sleep. I usually shut down my pc 2-3 times a day so I want to ask if this habit of mine will damage the psu or not.

    PSU's don't break when you turn them off.

    Do you mean the switch on back of psu (on back of computer)?
    There is a bios setting that keeps 5v on when comp is off for using usb ports for charging whatever.

    This comp is a gigabyte AM1M-S2H, & the bios setting is "whateveritis", you must turn it 'on' to actually turn it 'off'.

    I have a bunch of comps connected with KVM switch, & with the 5v 'on' it messes up the KVM switches. Plus the light on the mobo is annoying.

    Maybe this is your problem, the bios default is 'on'.

    Page 3-19 of the online manual shows the options for turning ON/OFF lighting.
    To answer your question, it should be fine if you want to turn OFF the switch on the back of the pw supply. You are not going to be able to charge a phone or whatever when the system is OFF like you can when the switch is left ON.
