Computer won`t turn on! I need help

[Speedbump4]

Hey guys I just recently upgraded my system and have run into a huge issue which I need resolved ASAP in order to get my files so I can continue to work on my paper.

I bought an ABS Tagan Bz series 700w Powersupply and I currently have an Asus p5k-e motherboard. My processor is a Q6600 which was Oc`d when I switched the PSU`s since my old one was a 500w.

The issue is that My computer won`t boot, there is power to the mobo since the green light is on. But I press the power button, only sometimes I will flash on real quick the LED lights from the fans will turn on and within half a second will turn right back off.

I know its not the mobo cuz I plugged my old PSU back in and it works fine and everything starts up.
Please any assistance is needed. I`m in dire need to get this up and running.
Thanks

You might have a defective PSU... since it obviously works using the old PSU, I would recommend exchanging your new PSU.

Reinstall the old PSU and run the CPU on base speeds until you can exchange your new PSU out.

Send the Tagan back and get a PCPower Silencer 610watt.
