All right then here it is, my pc is not turning on, on demand... but when it turns on it works perfectly fine, with no lags, shut downs or hangs, even after heavy gaming and some 3d simulation

i just turned it on about 30 minutes ago and it works perfectly fine but after i turned it off and tried to turn it on again.. it just wouldn't... need help soon as i have work to be done

my pc specs
i7-4770k
asus z87-pro
4x 8gb corsair vengence
2x nvidia asus gtx780 sli
8 fans
water cooled pump for cpu corsair h105

my dimms are running are overclocked speed 1866mhz using xmp profiling

seasonic 1250watts

i have a gut feeling that the power supply unit is a bit much and that i should get a lower psu

i sense that maybe the system might be overloaded, not sure even if that statement is valid? Just did a wattage calculation and my system only need 900watts so thinking if lowering my wattage would help?

You dont need a smaller PSU, your PSU will only output what the computer needs eg if you machine is drawing 900w the PSU will output 900w. Your PSU can provide a total of 1250w and wont output that unless its needed :)

It could be somthing as simple as a faulty power button if it wont turn on. To test this shutdown your machine, remove the side panel, remove the jumper for the power button and short the pins (simulation the button push. If it works ok then its a faulty switch. The case front leads will be plugged into this http://mxdtr.com/upld/ecs-jumper-setitngs-1.gif remove the power lead and short the pins to boot.
