My Seasonic S12II 80plus Bronze 520watts doesn't work

I just bought a Seasonic S12II 80plus Bronze 520watts and my cpu won't turn on

This is my build:

ASUS P8H61-M LX R2.0 LGA1155 PCIe 3.0ready
Intel Pentium g630 2.7ghz
Palit GTX 750 TI OC
4gig ram
1 hdd
1dvd

What I can connect from the PSU are:
24 pin connector x1 (to motherboard)
4 pin connector ATX 12v (to motherboard)
SATA x2 (to 1 hdd and 1 dvd)

I'm confident that I did nothing wrong installing the PSU.
For now I reinstall my old power supply to use my pc now.

Anything wrong why it won't turn on?

  1. You did flick the little switch on the PSU right?

    Otherwise if you're feeling ballsy you can try the paperclip trick to see if the PSU works at all. That's at your own risk though. http://aphnetworks.com/tutorials/psu_paperclip_trick
  2. Is the SB_PWR LED on the motherboard lit?

    lol I misclick the "best solution"

    I sure turn on the switch to " | "

    If I try the paper clip method can I still replace my PSU? Since I have a 1 week outright replacement

    If the motherboard isn't receiving any standby power then the power supply can't be turned on by the motherboard. That indicates a DOA (i.e. Dead On Arrival) power supply unit.

    Did you try the paperclip test to confirm this?

    If I try the paper clip test will the outright replacement or warranty will be broken?
    I will try it if its ok

    Can I just tell the store that "I tried the paperclip test and it did not turn on"? then I can replace it?

    The paperclip test does not void the warranty.

    The following video applies to any ATX12V standard power supply unit:

    That means the PSU is dead. Return it to your vendor for replacement.
