*UPDATE* - I sent the motherboard back to be tested for errors, and they have sent me a new one. The fault was with the motherboard.

Helly everyone, I'm new here. I hope I'm posting in the right place.
I have a problem with my recently purchased Maximus VI Hero motherboard. I have been searching the forums, but I can only find posts related to overclocking.
My problem is, that sometimes (not everytime, but fairly often) when I switch on my computer, the computer resets emmediately and powers on again (exactly as if certain BIOS settings has been changed).
But when it powers on again, I sometimes get the error message "SIO Power on Delay Fail. Press F1...". The odd thing is, that sometimes when the computer resets, it just boots normally, and does not show the SIO-error. That confuses me quite a bit.
I've mostly found forum issues relating to overclocking, but I run this setup at stock speed, and factory settings. I have been overclocking for a lot of years, but I decided to stop doing that, and bought this setup with that in mind (see specs below).
I have found a wikipedia article about this error message though, and it says the following :
"The Power Good signal prevents a computer from attempting to operate on improper voltages and damaging itself by alerting it to improper power supply. Power good value is based on the delay in ms, that a power supply takes to become fully ready. Power good values are often considered abnormal if detected lower than 100ms or higher than 600ms".
So it seems that it is related to the PSU. I have a Corsair HX1050 PSU, just under a year old, and it has been running flawlessly with an i7 2600K @ 4.8 GHz on an ASUS P8Z68-V Pro /GEN3 motherboard and dual AMD 7970 GFX (and later an R9 290), until I bought the Maximus VI Hero last month.
The motherboard runs at factory settings, except from disabled onboard sound. I've tried BIOS 1302 (was installed on the MB when I recieved it). 1402, and now even 1502 BETA, to see if that changed anything. No results.
Is it the PSU, can it be the motherboard? Or the new CPU (i7 4770K), what do you guys think?
Other parts:
4770K with @ stock with Noctua NH-D14. No errors with Prime95
16 GB Kingston Hyper-X Genesis 1600 Mhz RAM (No errors in MemTest86). I used them on my prior setup.
AMD R9 290 (with Arctic Cooling Accelero Xtreme IV). No errors in stresstests. Also used with my prior setup.
SoundBlaster ZxR soundcard. Also used on prior setup.
SanDisk Extreme II 250 GB SSD.
Seagate 2 TB HDD.
WD 1 TB HDD.
Thanks in advance for any help or suggestions, it is much appreciated.
