Motherboard RGB Lights Working, but PC Fails to Turn On

[Sturmgewehr_44]

I upgraded my system yesterday from a 4790k and Maximus VII Formula to an 8700k (and of course Dominator Platinum DDR4 @ 3200MHz).

Everything was normal afterwards. No problems whatsoever. I reused my AIO (Corsair H100i V2), temperatures were normal (around 60-63c all cores under 100% load from Cinebench). I played basically the entire night. I shut off my computer and went to bed.

I wake up this morning. LEDs from the motherboard are flashing and changing colours (Maximus X Formula has RGB lights all over it). I press the power switch. Nothing. Again. Nothing. I look to the I/O panel. The Bios flash button is not lit up (normally is green), but the RGB lights are working.

I removed my new RAM, one by one. Did nothing. I removed my 1080 Ti. Still nothing. I then made sure that the 24-pin and 8-pin CPU connectors and cables made adequate contact. Sure. S
Once again, did nothing.

So, I am now wondering about the power supply. I had to RMA it around 4 months ago (in March), due to random shutdowns. The RMA took at least two weeks, which I don't have time for (I'm moving to Europe in mid August) and bringing my PC with me. It seems that AX860is have issues with failure rates. However, everything seemed fine last night. I had no shutdowns or anything of the kind. The self-power test for the power supply failed. The fans did not even spin nor did the red or green LEDs activate to say whether it failed or passed the test. All it would make was a faint click with each push of it.

The last thing I did last night after shutting my PC off was removing the power cable and putting a US/Canada to EU cable in place of it on the power supply, to see if the PSU end of it fit. It fit perfectly. The PC was turned off at this point. Is this simply a coincidence?

have you checked your cmos battery on the mother board

Not physically. However, the I/O has a clear CMOs switch. For whatever reason, pushing it appeared to work (despite it not being lit up), since the motherboard LEDs stopped for a few seconds and then resumed again. However, it solved nothing.

If the power supply is completely failing the self-test (it only makes a click, no LED indication or fan activity whatsoever), that most likely means that it is the problem, right?. I RMA'd the PSU literally four months ago. The AX860i I had before lasted around 10 months. This model has a 8 year warranty, and cannot even last four bloody months?!!! Lovely QC Corsair! Wonderful...

I'll be getting a Seasonic next. However, then I have to deal with the cables, since I'm using Cablemod cables, and will have to spend even more to get a new set for a different make of power supply. Removed my life.
