Stupid question on my part but are you sure it was the power supply that popped, and not the speakers?

 

If your power cable was barely plugged in, and falling out, I could certainly see the interruption of power causing a speaker to "pop".

 

Just a thought.

 

 

 

~~  Edit: Nevermind, reading your question a second time, I see you have no power now.  I misunderstood.  Sorry.

Does a different device in the same outlet have power? I have never seen a power supply pop out a cord, this would be the first time if it stands true.

 

Power supplies can pop when they fail. Generally it is a capacitor that blows. That said. Try it in a different outlet or at least verify the one you are trying to use is working.

 

If you have a good working outlet and have no power, replace the psu. Sometimes when psu's fail they can take out other hardware with them. It is rare but happens. Most likely your other hardware is ok. It was nearlly always cheap power supplies that took out hardware with them from my experience.


If I am helping you with a problem and I have not responded within 48 hours please send me a PM.

Unless I just forgot I unplugged it first then yes the cord came out.. Would it of had anything to do with my new graphics card with a recommended PSU of 400 and only using 250 at the time. its just a Radeon 5450

It very well could be. If you over stress a psu you will burn it out more quickly, I am actually suprised it ran at all. If you stress an older psu they fail much more quickly. It is always best to have more than enough power at least 10% over what is recommended. I generally give myself 20% headroom on builds and I have never had a psu failure on my personal comptuers after using that method.

 

Lightning kills more psu's than just about anything else though. After a storm I generally got about 20-30 customers with bad psu's.

We had bad storms last night computer was off though.. The old PSU did not have its own power switch.. This morning it ran for about 20 minutes.. With that card it went a few weeks, if that was the problem. I wasn't him g it was normal,activity
