Has been working fine since i built it in February, Went to turn it on Wednesday morning, The fans would spins and lights come on but no display.
Tried all the usual like trying one stick of ram at a time and checking the connections. Turned pc on this morning came on straight away but i had no keyboard/mouse plugged in. Turned it off to put them in and it didn't comeback on.
Turned psu off and back on 5 mins later and it came on. Still on now has been for 20 minutes and it seems ok.
Got a choice of sending motherboard/GPU and PSU back OR just psu by itself as they guy at ebuyer tech said it sounds like psu faulty.
Would like to know for certain it is only PSU, unfortunately have no spare parts to try.

Seems like PSU is passing off, bad caps. Can't really blame anything else as you tried many available solns. MoBo won't go crazy in one day, and if it boots, MoBo is fine. You need a new PSU, CXM is poor quality unfortunately.

It sounds to me as though the guy at Ebuyer is correct. I would sugest that some kind of safety cutout is tripping within the PSU and turning the power off completely is reseting it.

I don't think the problem is GPU related though, as there should be signs of an issue there (beeping, if GPU was problem you'd test with another). At the look of it, it would more likely seem to be a power supply issue.

I don't know man , but I had a asus board [sabertooth] that kinda did this .. it would not restart like from windows restart at all but if I switched off the psu for like 5 sec, then I could restart the computer . in the end it was the board. after I replaced it , the new non asus board works fine as it should with all the same parts and psu's .
just a pain if I had to restart after a update , but as long as I did not use ''restart'' it seemed to start fine --

needless to say this was another asus product that fell short here and just stopped using them -- there not the asus I grew up with anymore

I was 90% sure it wasn't GPU as on tuesday night i was playing arma 3 and getting great fps and game was running good.
Using the pc now and it's fine, Will RMA the PSU. Thanks guys.
