Okay, I have 4 servers colocated. It seems that 3 of my power supplies have died. I don't know if it is like that because I am using too much power and the power supply can't handle it, or if the power supplies are just bad.
AMD Athlon 3000+
2x200 GB WD Hard drives
These all have a 300W power supply in a 1U rack. Hmm - if things are overheating inside, could it be that the power supply would go first? I just am a little lost on this one. Thanks!
Might just be a case of weird luck I would think, what brand of p/s's are you using? depending on the brand of course some are just higher quality than others. Also you may want to pick up some of the newer power supplies with PFC (pfc explained http://www.endpcnoise.com/cgi-bin/e/pfc.html ) that and a good ps like sparkle should be a winning combo
Can you add more information about this problem... such as:
1) Are these single or dual power corded system (assume single)?
2) Are these connected to power strips? If yes, what brand?
3) What type of ciruits are being used? L5-20, L5-30, L6-20, etc.?
4) What type of Racks/cabs are they installed in?
5) Can you disclose what colo/provider/location that they are hosted with/at?
Well it appears as though I've found a probable solution. The motherboard is bad. Its just a normal desktop motherboard, and began to suck in more and more power....until it blew itself AND the power supply. Ugh.
I am surprised that the motherboard could kill the power supply... You would think that any power supply worth anything would protect itself from anomalies occurring on its supported components (such as motherboards, disk drives, optical readers, etc.).
The reason that I asked the other questions is that I have seen this type of thing occur when there is an actual power problem, such as a faulty power strip, incorrect rack/circuit grounding, etc.
Please post the results of your fix. I am interested to see if replacement of the motherboard fixes the problem.
it is probably the power supply killed the mainboard. if a power supply is sending unclean power through the system it can kill components, just like a well placed static shock can. It doesnt take much to kill a computer component. I would replace both parts if i were you and upgrade to a pfc power supply to avoid power spikes and unclean power

Time to go fixing...
Just curious, how did you identify that its the motherboard (or think its the motherboard) ?
do you use a reboot port? i've had about 20 power supplies blow in the last 2 years on these cheap MSI machines we bought, they would never die in operation, we still have 10 or so in the datacenter running, they will run forever unless we unplug them, once you unplug it, its done will never work again, which is what a reboot port does. If you turn it off from the power button on the other hand, we seem to be able to prolong the death. These machines for the most part don't even have drives, they are pure pxe boot / nfs
We had to replace on one server the motherboard, processor, and power supply. The other ones seem about to go at any minute. Enough of these budget computers for me, time to do a real server machine.
I honestly don't know what the problem is. I'm just going to replace the entire server, and then diagnose it myself at home. The poor tech was working for forever on the machine and only got it working by putting in his own power supply and CPU with the new motherboard I bought for it.
I have 4 servers on one rack. Three have the exact same specs. The 4th has a different everything (diff motherboard, case, power supply, processor type, etc.). The 3 servers are having these problems, the 4th has had no problems at all.
They are all connected to the same current, etc. That is why I'm pretty sure that the problem has to do with my servers, and not what they are connected to.
The PSU was just the one that came in the 1U, so to be honest, I am not completely sure what kind it was. I would have to assume that its at least a semi-decent PSU, however, since it was meant to be in a server.
