Second SB died. Maybe PSU in question?

post #1 of 7
Thread Starter 
Hello everyone. I have had TWO (2) Sandy Bridge CPU's (and their motherboards) replaced after at least the CPU failed. A quick recap on the first failure: After months of worry free Overclocking and real-world use, I was running my sig rig (See below) at stock speeds. I go to start up a program which steps the CPU up to the stock 3.3ghz and all the sudden *BAM*, the PC shuts down. After troubleshooting I come to the conclusion that everything is fine except the CPU, which is completely dead. I get a new i5-2500K and after about 3 months it fails in the exact same manner. The PC will not power up, the LED fans will flick on for about a split second but will not power. The PC WILL power on if the 8-pin CPU Power cable is not attached to the motherboard (obviously nothing will happen without CPU power). I am now coming to the realization that my PSU might be faulty. It is a Corsair TX-750. Also to note the ASUS P8P67-PRO was replaced when the first failure occurred, so we are dealing with a new MoBo and CPU since the first failure. I have tried clearing CMOS-Battery, different graphics card (even trying to get a power-on with no graphics card), different memory sticks. I have double checked that the MoBo is not making contact with anything on the case other than the brass stand-offs.

I find it unusual that both 2500k's died in the exact same way under very light load. Money is not a huge concern but obviously replacing an i5 every 5-6 months is neither convenient nor the best investment.

Thoughts?

Your mosfets popped, at least that's what it sounds like to me, if the build turned on without the 8pin ATX cable in.

I don't know if the power supply can do that though.

Wow ok, first result on that shows several people having the exact same problem. I got 2 P8P67-PRO's both bad!? What luck, oh well, with Ivy Bridge on the way in hopefully the upcoming week I'll just upgrade to a Z77 and call it a day. Anyone know when I should start looking on Newegg for one?

Z77 is already out! They were released slightly before the Ivy launch!

Oh yes I'm aware of the Z77 boards being on the market. Just interested in seeing if newegg will have any combo deals with ivy bridge.

Uh oh. I've got one of those mobo's. It's over a year old.

Please don't die for another year or so. I have no money to replace you!
