Power Supply dead?

post #1 of 16
Thread Starter 
So I was chillin on the couch watchin some tv when outta nowhere I hear a big pop noise.
I turn around and see my pc and monitors turn off.

so Ive taken out my power supply, checked all the caps on my motherboard, all the caps in my psu and I dont see any blown ones.

It's a Enermax Galaxy 1000watt, (EGX1000EWL)
I believe the 120mm fan in the bottom of the psu is dead though as when I spin it, it really vibrates.

When I try and jump the power supply by itself, it powers the LED on the back which turns red, and it beeps twice, then waits a few seconds and beeps twice again, over and over.

either way it wont run, but wouldnt be nice to know what happened if anyone knows.
thanks.

Ive had the power supply for like 5 maybe 6 years.
I dont think its ever been really stressed. it had a dual core when i got it, then a Q6600, and now the 2500k.

Its not under warrenty anymore though.

When I goggled it I found this.

"PSU Status: unable to power on, or suddenly off
LED: red light
Buzzer: two beep interval
information: 1. power supply abnormal, protection circuit activated.
2. connector terminals are short-circuited."

which sort of makes sense, cause when I look at the 2 cables going into the power slot (where you plug it in) they do look like they could be burnt.

Component got blown and PSU went into protection mode. Without knowing exactly blown, do not attempt to power it on. It might do more damages. Check if it it's the fuse or it has one, if not, RMA.

hmm, well mine looks like the last one in your photo, where its white, not clear glass.
I dont have a volt meter to test it like that.

Do you know where I can buy another fuse like that?
I dont think they could be that expensive.

Get it from Radioshack around you. It's $0.5~1 each.

 

Make sure to get the same current ratings. Or just take the one from PSU as sample. At this point it's not sure the fuse is blown. So just bring the whole PSU to hardware store. They have a multi meter to test.

Alright, well im going to take the fuse with me, and see if I can find another one (says 20A 250V)

So say if that is the problem, what are the main causes for it to blow like that?

EDIT:
as well, I'd like to replace the 140mm fan, its still a 3 pin, but the header is small, so I cant put any of my extra 140's in.
are there special types of fans I have to get?

Thanks again, much appreciated, rep given smile.gif

This could be the only reason or others, can't say for sure.
