Ok this is a bit of a head scratcher.

List of parts in PC:
OC Force mobo (water cooled)
4770k cpu (water cooled)
2x 780 in sli (water cooled)
XFX 1050watt PSU
2x 8gig ram
Creative sound card
3x SSD
1x hard drive
All done in acrylic tube. So a right pain to remove.

Ok, front switch on 900D does not start pc (well occasionally it does)
Switches on mobo do not turn on pc.
Have set up keyboard and or mouse to switch on pc, this doesn't work.
when pc is on and I set it to sleep mode, nothing gets it out of sleep.
When I pull the plug out the wall and push it back it, sometimes this will make it work, sometimes.
Other times I have to leave it unplugged for a while. Then plugging it back in will start it up.

Any help on this one much appreciated
 
It use to work ok.
Have set bios on numerous occasions. Even switched bios still not working.
I would have said possible PSU but it's a good one and not very old.
 
Ok little update.
Pulled PSU cables out and linked green to black. Switched PSU on and nothing happened. Switched it off and back on and it started up. Tried again and it didn't work. On off one more time and it worked.
Looks like PSU is not working properly (I hope it's just that). Only purchased 5th August 2013.
Guess I order a new one and if it works ok will have to RMA back to Overclockers.
Though Overclockers don't stock the XFX one anymore
 
Have replaced PSU with a 1200w Super Flower. All working properly now.
Have requested RMA for XFX PSU, it's not a year old yet!
