White smoke inside case? PSU maybe?

i turned my pc on and was on it for about 20 mins then i turned around for 2 seconds when i turned back it had turned off...... so i tryed turning it back on and the fans went on for about a second and turned back off. i has a look at the case and there was white powder everywhere. ive only had this pc for 3 months the specs are

Intel i5 2500 3.3ghz
xigmatek asgard case
PNY 560 ti
1tb harddrive
650watt corsair TX

It has a standard CPU cooler and 4 case fans. PLEASE HELP!

  1. It is possible that one of the capacitors got fried. The PSU would be my first suspect. Look into RMAing the PSU after you perform the simple "paper clip" test. The paper clip test will confirm whether the PSU is dead or not (not a test for under load).

    jemm's link will show you the paper clip test. This test will tell you whether the PSU is dead or alive; it is not a load test.
  5. Thank you i will try that. but for what reason would it do that? i havent overclocked my cpu?
  6. Another place to look at is the motherboard.

    Please ground yourself by wearing an anti-static wrist band - http://www.newegg.com/Product/Product.aspx?Item=N82E16899200012
    (I use a home-made one - 2 alligator clips attached to a 6' length of 14 gauge stranded wire)

    It could be due to a manufacturing defect resulting from a bad capacitor. Bad capacitors do slip through final inspection and testing sometimes. (The price of perfect quality is infinite!)
  8. yeah could on the MB , or even a Mosfet ..my buddy had an older were rebuilding ..put everything together , turn it on ..and I could smell burning plastic ..and saw some smoke coming ..upon close inspection it was a little black Mofset on the MB had fried

    Yes. Get the one I have - Corsair HX850 - been in service for 2 years; works flawlessly. It is available in the UK, but I don't have a link for that.
