• Smoke came out of computer
    12 replies, posted
So I built my machine years ago (2007?). I've upgraded it a few times since: adding a bluray player, upgraded the graphics card, updated CPU/Mobo/RAM. I was jut browsing the internet and suddenly I hear a pop and I see some smoke. I immediately shut down windows but noticed it didn't take long at all (it probably died). After pulling apart the computer I found the source of the smoke: the bluray power cable melted or something. Even after unplugging the bluray player the computer won't turn on: some of the fans turn a tiny bit for a second but then nothing. I'm hoping nothing else is dead, I'm going to replace the PSU. Any ideas what caused this? Just and old PSU? How can I test if other stuff is dead? How do I know what kind of PSU I need? I had a Zalman 850W before, 850 watts was probably over kill so if I really need less that'd be nice.

I have never seen a more perfect juxtaposition between avatar and post content.
It can be caused by a number of things. Most likely is a short, bad wiring, or just age and failure. I don't know what your specs are though to suggest a PSU.
i5-3570k 6950 2 GB 16 (4 x 4) GB DDR3 RAM LED 120mm fans Bluray Drive (when I can get a new one...) 1 7200 RPM Drive (though I'd like more)
I've seen this before, something about a bad solder or something, i doubt it was the power supply
It was likely something bad in the power supply. I've had 4 or 5 PSU's blow up on me in the last month. Any 500-600w bronze or higher PSU from a reputable brand will power any normal single gpu system. Look for corsair, seasonic, coolermaster, xfx, rosewill, etc
The bluray drive is probably repairable with some wires and soldering

nice, lucky it didn't bring your mobo and CPU with it! count your blessings there

Most electrolytic caps are only rated for 2000-5000 hours at their rated temperature (85-105C) so old caps are going to have higher ripple and a lower ability to regulate voltage compared to new caps.
