Burned out Power Supply

post #1 of 7
Thread Starter 
Hello everyone,

I had a little surprise last week when I booted up one of the computation computers that I use. A short time after it booted, it started smoking and I immediately shut it down. Once I got it unplugged and let it cool down this is what I found when I opened it up.



Luckily there was no drive in the hot swap bay that got fried. Everything else looks normal and there is no other visible damage to the machine. My questions to you all are

1. Do you think that the power supply was the cause or do you think that it may have been another component?

2. What power supply would you pick to replace the one that is currently fried? It was a Supermicro 865Watt (PWS-865-PQ). As far as budget goes, the university that I work for will pay about $300 USD for all replacement components before they give me a hard time. That doesn't mean they won't pay more though if I can justify the cost.

Computer Specs:

Processors: Dual Xeon E5504 @ 2.00 GHZ
RAM: 12 GB Triple Channel
Motherboard: Supermicro X8DAH
Graphics: Nvidia Quadro 2000
HD: Two 1TB Seagate Barracuda in Raid 0 (They wont let me change it to raid 1)
OS: Windows 7 Ultimate 64-bit

I would really like to save this computer from the trash heap, which is where it is currently headed, so any help would be immensely appreciated. Thanks!

A 550 watts PSU could cover that system fine

That is if you are going to replace the old one which you sould pretty sure its a no name PSU

And yes i think it could have very well been the PSU but i cant say for sure

That looks weird, like something got shorted so all those wires overheated from the excessive current (but no problem elsewhere).

Not like budget is a huge concern, but you'd need to go higher than the 550W range to get something with dual EPS12V connectors anyway. There should be a lot of decent options. Considering the price, Cooler Master V1000 for $170 (before $20 rebate, which... uh... you could fill out for yourself?).

By the way, if the layout of the case is strange and you need something with a 80mm fan that blows through, you could get an old Antec High Current Pro 1200 or something else.

That empty hot swap bay should have seemed just like a dangling power cable to the PSU. IOW unless the PSU's connector had a short inside, the PSU wasn't at fault. So I think the hot swap bay had a short in it, or the PSU connector was very crooked. If you have another hot swap bay like it, inspect it carefully, visually (especially peer inside the SATA connector) and with an ohm meter (check for shorts between each pin and ground and between the pins). Also cut off that cable, right at the PSU box, because it's obviously melted, and actually the cable should be cut off at the circuit board inside.

SuperMicro is a high end company that produces a lot of server and industrial motherboards, and apparently their PSUs are supposed to be very good and probably produced by Lite-On. If somebody else will pay you for a replacement, consider going whole hog and getting a PC Power & Cooling PSU.

I am replacing the hot swap bay, all of the sata cables, and the power supply. I am leaning towards a Corsair HX850 and tossing the Supermicro (sadly). From what I can tell from taking the bay and connector apart (there isn't much left) it looks like the ground wire went to the center of the damage which is very strange so I would guess that the cause was the hot swap bay.

You dont need 850 watts even with two video cards

Corsair HX850 is a great choice and should last a long, long time even putting out high power 24/7/365.

OTOH I hope you reconsider tossing that Supermicro because all it needs is a new SATA cable. At the very least, give it to somebody who can solder in a new cable -- after you cut the original cable right at the case so nobody will try to splice it to a new cable (new cable must be soldered right to the circuit board).
