Power went when turning PSU on?

post #1 of 7
Thread Starter 
Okay, so first of all; There is a "frequency noise" when the computer is turned off, therefore I usually turn the PSU off at nights (I have my PC in my room).

Now, sometimes (Well, has only happened twice) when I turn my PSU back on, the power goes out. (I mean power outage)

Not a big deal, but I wonder if this can happen sometimes? Also, the PSU cable is not connected to a grounded outlet.

Thanks thumb.gif

This might end badly. Are you seriously willing to sacrifice your rig so you can use THAT outlet?

I mean, I don't know why it happened. I was just wondering if it happened due to not being connected to a grounded outlet..

Why are you using your pc on a non grounded outlet? That is the question.

You are sacrificing your entire computer to go the easy way out on an outlet.

Not having a way to remove any kind of potential in amperage can be a serious cause to a great many problems.

It's not a good idea to use an ungrounded outlet. If your PSU has a frequency there's probably something wrong with it or the caps in it are making the noise. You should also use a surge protector for your stuff too in the event of power loss.

Well, my dad doesn't hear the noise, so I don't know if only "young" people hear it.

Anyways, I've switched to a grounded outlet now, and I'll buy a UPS later.

Yep, being in the electrical field, I know the dangers of not using grounded outlets, especially when it comes to electronics. Its safer for your equipment, but more importantly, its safer for you.

Also don't buy a cheap power bar, but a nice APC one or one that actually warranties the stuff plugged in to it.
