I think my PSU is dead?

I have noticed an odd noise comming from my system over the last two days. I initially though tit to be something brushing against one of the fans in my case. I stopped each one carefully to determine the noise was comming from inside of my power supply. Today I was running Prime95 to test out my overclock stability and poof. The entire machine went down and will not come back on. I have unplugged every single cable fromt he power supply outside of the motherboard and the best I can get is a half-second flash of light from the PSU and then it is back off. This is less than two months old and a 550watt PSU. Any ideas?

I snagged this from MechBgon in another thread I thought maybe this would help troubleshoot this problem.

Probably is the PSU - if you are lucky.

If you are not lucky, it might be a short on the mobo, or the cpu.

have you got an old system lying round that you could borrow the psu from, just to try the mobo / cpu / ram / vga
 
I am pretty certain it may indeed be the PSU. I have another machine to work with, but will be able to try that out tomorrow. I will try out that PSU in this system as well as vice-versa. I am praying it is just the PSU, but I am still miffed if it is, because this is not a cheap PSU.
 
Think of it this way - -
If the psu has gone, then IF it was a surge, the psu did what it is supposed to do, and took the bullet. Better that than the rest of the system.

Good luck
 
Don't think it was a surge. I think the PSU was faulty. Needless to say I am miffed that this nice new 550watt PSU is a pile of crap
 
A good way to eliminate the possibility of a surge/power spike is with a quality UPS unit. I have two APC Back-UPS XS 1000 units for my computer and other important/expensive hardware. With those two units, I get enough battery time to safely shutdown during blackouts and be protected from otherwise crappy power. I'm thinking about getting a third unit, either another 1000 or a 1500 and include my DSL modem on the battery lines. With the modem, router, and ethernet switch on battery, I'll be able to stay online until my laptop runs out of charge during a power outage...

I'm sure the UPS units I have have saved my systems more than enough times to offset the cost of getting them. Plus, the battery aspect is a good thing to have. At least for anyone living in a part of the country that has power failures (not many parts of the world that don't get them, it's just a matter of how often you get them).
 
I do not often get power failures here or even surges. I do have a high end surge protector on the system though and the PSU itself has a built in fuse that should blow if it were a surge. I beleive it may have been a case of overheating or porr solder joint on the board after some closer examination. I am distraught, but newegg.com has already issued me a new RMA and the new PSU should be here next week. I simply have to do with my backup computer for the time being.
