Power Supply BLEW UP?

[ax77]

Hey everyone, so I'm gonna try to make this as short as possible.... and I think I know what may have caused it.

So basically my Internet router kept shutting off by itself, restarting etc... so I called a technician. The guy told me to plug the router power cable to the wall outlet, saying that may have been the problem. So what I did was, I moved the power bar cable from the first outlet, to the second outlet.

Started up the computer... everything was fine... was listening to music I think (not sure) and then boom... computer shut off. It sounded like the sounds were coming from the power supply.

So I unplugged the PSU.... plugged it back in, but the computer doesn't want to start. But I still see a blue light on the motherboard (power light or something) but the computer doesn't wanna turn on...

So, do you guys think that my video card or anything else may have been effected?

Please let me know...thanks!

Woah. First, don't post this twice, although I do understand your urgency.
Try getting a new power supply, and test it out.

But, I have a question for anyone on these forums...could this happen with an inadequate power supply (not enough watts/amps per +12V Rail)?

OP, it does sound like the PSU is fried. If you have another known good PSU to test with, you should try that first. If not, a new PSU is probably your only option.

To digitalhardware, a PSU that is overloaded can certainly do that, yes. A good PSU should just shut itself down before any damage occurs, but there are many bad ones that won't.

Alright, good to know. This just stresses even more that the PSU is very, very, very important in a computer build. Yet, it is the most overlooked.

Absolutely right. There are many people that want to go cheap with a PSU when they don't understand that a bad PSU can cause a lot of harm if something goes wrong.

To the OP...what brand and power rating is the suspect PSU? It would also be good to have a list of your system specs to understand what sort of power it would draw in the first place. It sounds very much like a blown PSU, though; the router issue is a red herring (although if you have a wider issue with your electrical supply, it may have been a contributing factor).
