PSU: Plug in or not to?

So far, I've place in the PSU into my case.

I've read online multiple articles:
  • One said to leave PSU unplug and build.
  • The other said to plug in PSU but turn it OFF.


Which one is better?

if the second option: Do I plug it in it in while the switch is on or off?

  1. Shouldn't matter really. I do my builds with the PSU unplugged. Some people swear by keeping it plugged in. I think its a crap shoot. Grounding yourself is WAY more important.

    I = on and O = off.
  2. Well when plugged in.... case is grounded (assuming house wiring correct)

    Could be bad. Likely would be fine. You will have way more issues after you power it up if your house is wired incorrectly.
  5. I built mine unplugged. Take care to build in a static-free environment if you do so.

    If you have problems with static then it would help to plug the PSU in if your house is grounded correctly. Just make sure the power switch is in the off position and for extra protection do not plug the main motherboard connectors in until you need to that way when you touch the case any static will go to ground. A anti-static wrist strap would help also.
