Been having this problem where the com won't boot up normally while pressing the front panel power button. It's a seasonic X1050W. I would have to flip the psu switch as fast as i can between I and O for almost 30 mins to get it to power on after each shutdown. If i go to sleep mode instead of shutdown it boots up after 2 to 3 flips of the main psu switch.
Edit: Power is being suppplied to the mobo( mobo power on LED is glowing but it wont turn on )


First time the problem occured, it was found to have a faulty 3.3v rail and was RMAed.

Then a few months later, the second psu had the same problem but with no discernible faults with voltages.All the voltages from the rails were fine. Was RMAed again. But the third RMA had the same problem without any discernible fault with the voltages after only a few months.

i have checked every component individually like mobo and etc, brought them down to svc centre but they were found to be fine, including the psu which was strange so i swapped in my brother's psu and it booted up fine, no problems at all. Only my psu has this problem.

Did a memtest on mobo, no problem at all, surge protector and wall socket are okay so im not sure what's the problem..
I am also having similar issue like u. sometimes when booting up the com, it keep restarting after the window logo. i do need to turn off the PSU switch for abt 5-10sec & restart & everything is back to normal. sometimes during gaming, com will also freeze & auto restart, & i have to redo the same process again. had been adapted with the com mood already~

Actually booting issues may not always be PSU. Suspects can be graphics card or hard disk.

Did you have to flip the main psu switch while holding the power button at the same time?

+1

Certain cold boot issues may be due to GFX and HDD.

I used to have an issue where I couldn't turn my PC on after shutting down. I.E. press power button but it doesn't turn on. Usually after being powered off for a long time (few hours) it will turn on when I press. But following an immediate shutdown it won't power up.

Turns out the Palit HD4850 was the culprit.

Seasonic X power series has this issue, last time mine 620W also got this issue. cannot on via the power button have to on off the main PSU switch several times den it will work. Until one fine day it died completely den I went for RMA.

Seems like it a common issue with a batch of the series. Change to a newer model features the hybrid fan and it got a mini upgrade to 650W. After that no such issue for me.

My friend and me bought the X660 on the same day and both developed the random cannot power on issue after about half a year. Their RMA replacements have been rock solid though.

I'm using a Seasonic X-850W for a year+ and recently had the same problems. When I perform a cold boot, the comp will not boot but gets stuck somewhere at the booting process. After this I hard reboot a few times also cannot. Frustrated, I turn off main PSU switch and that usually will resolve the issue and the comp can then boot.

Is this the same issue you guys are facing?
