PC suddenly loses power

[Junzesn]

HELP PLEASE! I've recently built this PC http://uk.pcpartpicker.com/user/junzesn/saved/3wt323 and it ran fine for a day while i uploaded the drivers and installed the software i needed. However the corsair link software was not identifying the h100i CPU cooler on windows 8.1, after watching some guides i fixed this problem by turning the following registers to 0  AllowIdleIrpInD3, DeviceSelectiveSuspended, EnhancedPowerManagementEnabled, SelectiveSuspendEnabled . When i built the PC i left the built in fan hub untouched, i changed my mind about running my fans on max speed so i took the fan hub out and connected the fans to the motherboard. Then when i turned the power supply on, none of the LED lighted up and i was not able to turn on my PC. i turned off the power supply and unplugged it from the socket, after a while tried again and it booted fine. then after several hours the PC suddenly lost power and would not turn on for a while again. when it did turn on i attempted to fix this problem by disabling  the motherboards auto surge function. after while using  the PC it suddenly restarted by its self. the next day i ran the PC for several hours and tested it using prime95 and i saw that the temperatures where fine, i left it running for 45 mins and the CPU temp did not exceed 78 degrees but i did notice the PSU fan did not turn on, i think this is due to its function that it only runs at certain loads. again after several hours the PC lost power but this time when the LED came back on and i tried to power it the chassis fans would not turn on but everything else seemed to  including the CPU cooler, but it did not boot. at this time i took out all the wires and re wired the PC and tested the PSU with the built in self test which it passed. i don't know what the problem is and i'm worried that it may occur again if you have any ideas why as to all this happened and how i can fix it please tell me.

so when you rewired your pc it hasn't happened again so far...? i think you may have not plugged a wire in properly or something like that

Thank you for the response, and yeah so far it hasn't lost power for the last 9 hours but, it's previously been turned on longer then that and, the wires seemed to be put in well when I was taking them out.

Have you tried using a differed PSU? There might be something wrong with the one you have.

Nope, I don't have another one.
