WBernbaum Posted December 18, 2007 Share Posted December 18, 2007 I just completed the assembly of my first ground-up PC build. I selected a Corsair HX520 modular power supply after reading several very positive reviews from around the web, but after pressing the power button, my excitement turned to panic: I smelled (and saw) smoke. :eek: This occurred after about three seconds, and I heard a faint crackling sound as well. User error is not out of the question, but I have upgraded power supplies, video cards, and memory before, so I have a reasonable idea of what I'm doing. I assumed the power supply was the culprit, as I'm sure it would take more than three seconds for the CPU to overheat, especially with a Tuniq Tower. However, I guess the motherboard could also be to blame. Any Ideas? Thanks for the help in advance. Link to comment Share on other sites More sharing options...
EliteKiller Posted December 18, 2007 Share Posted December 18, 2007 Smoke is never a good thing. I'd pull the motherboard out of the case and start looking for burnt traces/components.Sniff the psu for the "burning electronics smell" and test it with a DMMHook everything up outside the case, verify that you have everything connected properly, and power it up again. If it smokes at least you can see where it's coming from. :flamethro Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 18, 2007 Corsair Employees Share Posted December 18, 2007 If this came from the PSU then it needs to be replaced. Please use the On Line RMA Request Form and we will be happy to replace it. Before removing the PSU, I would double check all your power connections and make sure that everything is plugged in securely and that none of the connectors are plugged in backwards or upside down.

WBernbaum Posted December 18, 2007 Author Share Posted December 18, 2007 After waiting for a short while, I tried powering up the system again. The system didn't smoke this time, but it turned on for three seconds, turned off, and came on again. This cycle repeated until I disconnected the power. I tried with another power supply and obtained the same result. I assume that the motherboard is faulty. Whether the mobo was DOA, or the power supply killed it, I don't know. Should I RMA both through Newegg, or RMA the power supply through Corsair? Would any other components be damaged (ie CPU, RAM)? I'd like to know the most efficient way for me to remedy this situation. Thanks Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 19, 2007 Corsair Employees Share Posted December 19, 2007 It is hard to know which components are damaged unless you are able test them in a known working system. If you are already shipping the motherboard back to NewEgg then it may be more convenient to have them both replaced at the same time, however we have no problem replacing the PSU for you!
