[SOLVED] New built PC not turning on

[aa1991aa]

Hello everyone so I just put together a PC and when I switch on the power supply , the RAM RGB turns on however when I press the on button nothing happens . I double checked all the connections , The wall plug is also working . I am suspicious to the PSU . I did PSU test with a paper clip and it didn't turn on . Before I return the PSU is there anything else could be wrong ?
Any idea appreciated

Do any of the fans spin when you try to turn it on?

Disconnect and reconnect all cables and remove anything you don't need to POST. Start with 1 stick of RAM

I had a similar issue on my PC recently and I believe the front panel connectors were connected the wrong way around, so may be worth just scanning your eyes across those too.

Thanks for the reply . When I switch the PSU on the RAM RGB + a tiny led on the case hub turns on. When I press the power button on case, Nothing happens at all . I did double check the connections, no luck. I am suspecious to the PSU but my question is if the PSU has issue then why RAM RGB turns on ?That means there is power to the board , right ?

Not necessarily. There might be enough to power the LEDs but not the entire system. Swap it out for a good known PSU. Let us know if it helps.
