Major Help

First build. I took my time, I double checked & triple checked all the connections. When I plug in & turn on power I get nothing. I mean no sign of anything.

Could I have a bad PSU? It's a Corsair TX 650. I'm clueless at this point? I was very careful with static & all other precautions.

Please help!

  1. Do you have another PSU to at least test with?
  2. Sometimes when you plug the power button into the header in the motherboard, you might put it in upside down.

    I have done this countless times and doesn't hurt to flip the connectors around.
  3. Not to patronise, but there's a switch on the back of the PSU that needs to be flipped too. Also try changing the kettle leads over - your monitor likely has one too - to make sure that's not faulty.
  4. I think you should take into account the two power_switch pins.Are you sure you put them both correctly?

    Have you tried a screwdriver over the jumpers?
  6. When dealing with these issues, always look for the most obvious fault first, so work from the plug socket on your wall, making sure everything is on.

    Which pins are we talking about. Help me out here?
  8. PSU & PSU switch are supplying power. I tested with an electrical tester.

    I will check the power button. I'm assuming this is one of those tiny 2 & 3 pin headers that all go around the same area in a tight fit.

    The only other possible is the 24 & 8 pin power connections, but I think those can only go in the right way.

    I just can't believe I don't get even the smallest sign of life, nothing, zilch, zero.....

    What to do next?
  9. Make sure the powerbutton connector of your case is properly connected to the motherboard.

    And you could always post some pic to show if everything is indeed properly connected.
  10. is the ps switch 2 pin positive negative in the right correct placement?
    This gives power to the machine.

    Kind of tough when you don't divulge much information.
    Motherboard ?
    Case ?

    As long as the pwr_switch connector is on the proper pins, polarity doesn't matter.
  12. I recently purchased that same power supply and it turned out the AC power cable was bad. After trying all the hard stuff first I replaced it with a old cord I had and the thing powered right up. It took Corsair a month to send me a replacement, their customer service is "lacking" from previous days.

    I'm suspecting the case, since the power button does nothing

    I tried that last night at 1:00 Am . I snagged the one right off my old system and nothing. Power flowing through the unit & it's cables, I'm suspecting the problem from that point.

    Swap the pwr button connector with the reset button connector and see if pressing the reset button will start the machine.

    Still haven't named your components.

    Could the case have bad wires? Let me know if theres any other part I missed that would help solve this ........Could me cpu be damaged? if so would that cause no power at all?

    You're not getting anything at all ? On board switch not lighting up ?

    Nothing at all. And just now I got no electrical current reading from the PSU. This just got more confusing....................

    That's it. I'm sending the PSU back. Since I don't have another one to try. I'm praying that it was doa.
