Did my PSU go bad or something else?

post #1 of 8
Thread Starter 
So, I'm kind of freaking out right now...

My computer is about a little less then a month old, and today I was running a 12 Hour Prime95 Blend run to check my overclocking Stability.

I was in my living room and I heard a pop, I had no idea where it came from so I thought nothing of it. When I came back into my room an hour later, I smelt a very strange odor, like a hair dryer. My AI Suite II also reported an abnormal voltage spike in a 3V area.

I turned off my Computer and the smell went away. I was confused, so I turned it back on and began sniffing around my case. The smell seemed to come from the area between my PSU, where the wires came out and my motherboard. I checked around and couldn't see anything strange. Turned it back on again, still no issues, but the smell came back.

I disconnected all my components and removed the heatsink to check for blown capacitors. Couldn't find any. So I tried turn my computer on again, while everything would turn on again, my Monitor wouldn't show anything. The fans on both my Graphic Cards were spinning, and I tried reconnecting the monitor, it didn't help. Turned it off again and felt the wires to see if anything was really hot. Everything felt normal, but I smelt the odor coming from a stronger source, it came from one of my red cathode lights, I felt it and it was ridiculously hot compared to my other ones. I pulled it out and it had burnt marks around the edges. I took the little blue box that came with it and opened it up.

Behold, a blown Capacitor, literally burnt to a crisp. I check the molex that connects to it from the PSU and their weren't any burn marks or anything abnormal. However my Monitor still doesn't show anything when I turn it on. So I just took the PSU out and put it away for now.

I'd like to know if this is the PSU's fault, or just a faulty capacitor from a 5 dollar cathode kit? Is it possible the PSU took anything else out with it, including my 2 Graphic Cards? I tried connecting both to the Monitor and their was no picture, even though the fan was connected. Could that be because of a safety feature? If so, how can I check? I already looked into my PSU with a flashlight and couldn't identify anything strange. I don't want to open it up for a more thorough check because of warranty issues.

Should I just RMA my PSU and hope for the best when trying my a new one? I was told Enermax was one of the best, and for the price I paid, I really didn't expect this to happen so soon.

I'm not too experienced with computers, I still consider myself a newb beyond simply assembling, so I'm concerned I just made things worse by turning it off and on to find the source of the smell.

I had that very same thing happen with one of those Cathode kits. Little blue box burnt up. Ive bought tons of those kits though and that's the only one I had a issue with

It's simple-Try with other PSU,or try another monitor.One of those little blue boxes tryed to Kill my Fortron Bluestorm PSU(Short circuit) But I've saw the spark and beat the hell out of it FAST(no damage to the psu)Annd from then i do not use catodes.


PS-i've used ones but with separete psu and all of the boxes out of the case

Can anyone tell me how I would go about checking my other components for damage? I couldn't find any visual evidence. Other then the blown capacitor and scorch marks on the Cold Cathode Tube not of my other components had anything like it. Is it still possible that I fried something?

Until I get my new PSU to come in on Wednesday this is going to eat away at me. I currently have no way to check the other parts because I only have one other PSU and its a 500w Antec that can't even run two 7800 GTs.

I'm extremely fearful of frying my Motherboard and Video Cards. However my Motherboard's LED came on, so I should be ok there, right? However, my when my Computer turned on, it wouldn't post. I couldn't get a signal, and I tried plugging in the DVI cable in both my GTX 580s, is it possible that the PSU damaged them?

Only real way to check them is to test them. More then likly the CC box just died and you PSU short circuit protection kicked in.

So the strange hair dryer smell from the wires is normal?
