So I built a gaming PC for my kids on Friday - my first full build and everything went perfectly, switched on first time - no problems with Windows installation - a great feeling. The boys have been happily gaming since but we left the PC on a couple of hours ago, took the kids to the park, came back and now there is no power at all and won't switch on. I tried using another power cable but that made no difference.

Any idea is what may have caused this? I did skimp on the PSU a bit - I bought a 650w Kolink plus rated one. It's powering a Pentium G4560 on an ASUS Prime B250M-K motherboard and a Fury X GPU (I know the CPU will be bottlenecking the Fury X but the PC is for my 5 & 6 year old boys playing on a 60Hz 1080p monitor so it doesn't matter). Stock cooler, 1 HDD, 1 SDD and a PCI wifi card. Front case fans with LEDs are also powered directly from the PSU rather than plugged into the motherboard.

I know the obvious to do try would be to try swapping out the PSU with the one from my own system but given the time that's going to take is there anything else I can do before that?

Edit: Not sure if this is relevant or not but the PC was plugged in to a 5 meter extension lead. I did just try plugging the PC in to one of the main sockets but still no power. I'm sure I remember hearing some electrical/static noises when I plugged in the 'kettle' lead on Friday (there is no power button on the PSU) - again not really sure what that might mean?...

Check if you are getting any power from psu to motherboard first. Such as any led lights on motherboard. If you do skip to "If you are getting power to psu" if not continue below....

If you are getting power to psu ( psu fan turning on ) then reset motherboard cmos by using clr jumpers on motherboard or by removing battery as below:
  • Disconnect power cable from psu.
  • Remove motherboard battery
  • Press power on few times to discharge all capacitors
  • Then put battery back in motherboard
  • Connect power cable and try turning it o.
If its still not working you can either try your other psu or try starting your pc with bare minimum stuff to test such as disconnecting all drives, graphic card and using single memory or single memory in different slots with onboard graphics.

Thanks for the advice. Managed to get it sorted. Removed all the PSU cables and did the paper clip test - passed. Plugged mobo 24 pin back in - led lights showing. Had a hunch then it was the power lead for the front case fans with LEDs - this turned out to be the problem. Have the PC back up and running now minus the front case fans, I think I should be ok to run the PC without them for a while until I decide what to do as the Fury X is water cooled anyway and CPU is running at stock frequencies. The case was a B grade Kolink Punisher case picked up from OCUK - I suppose I should return the case for a replacement rather than fit alternate fans?
 
If its under warranty and you dont mind the down time you can. Maybe they will send you replacement fans instead or if you dont mind the cost you can fit alternative fans.
