[SOLVED] Is it okay to leave the PSU plugged in but switched off?

[TraceL]

I wanted to fully turn off my computer since I am going to be away for a while. I thought leaving the PSU on and plugged in would be fine. However when i clicked on my mouse the LED of my mouse lit up.

Because of this i thought my computer was still on. I decided to switch the PSU off and see if the LED of my mouse will turn off. When i saw it was still on, i tried turning on my computer while the PSU was switched off (still plugged in). It booted only for half a second and then turned off, including the mouse.

Can i leave my PC at this state? I’m already out of my house so i am kind of worried.

Sure, and it's definitely not a bad idea to do this when away for a few days.

An additional wise precaution is to turn off any UPS units that you have connected to computers, TVs, stereos, and the like....not security systems, though.

The only thing this may 'hurt' is the CMOS battery's lifespan.
