PC Power Supply / sb power flashing

Hello, I bought a new Corsair 350W power supply to connect to an Asus M2N E SLI motherboard. The problem is that the tower won't start and the sb pwr LED on the motherboard is blinking instead of staying solid.

Here's what I've tested:

- I tested the power supply by shorting the ps-on and ground, and the power supply works.
- I connected the power supply to another tower with a Gigabyte motherboard and the power supply works.
- I tested a 250W FSP power supply on the Asus M2N E SLI and the power supply works, and the LED stays solid green.
- I tested the Corsair power supply on the Asus M2N E SLI by removing the RAM, HDD, USB devices, graphics card, and leaving only the CPU, and the power supply does not work.

When I say that the power supply does not work, I mean that the green sb power LED blinks instead of staying solid.

Thanks in advance.

      No, I haven't unplugged anything at that level. On the panel, I have the power led+, power led-, the hdd led, and the power sw that are connected.

      OK

      I don't see the exact cause

      I've never had this case.

      Is it a bad contact between certain power supply wires and the connector?

    it's possible, we cannot rule out this hypothesis
    but knowing which contact

    Hello, I tested the power supply on another Asrock motherboard and the same problem occurred, it doesn't work. I'm going to replace it.

    Thank you for your responses.
