I am building a computer and I have installed the mobo, power supply and fans so far. I wanted to test things to make sure they were all running smoothly and I noticed that every 6 seconds my entire system looses power for a split second and then continues as normal, but the leds flash, fans stop then start right back again, and the mobo's leds shut off and turn back on. is this an issue with my power supply?
 
Check motherboard manual for power connections and make sure they are completely inserted where they belong...

In fact, it probably needs cpu and heatsink fan in place to do initial test (this should result in beep code for RAM error - as none in place... then beep code for video error, when RAM in place) .... https://lifehacker.com/6-essential-tips-for-first-time-pc-builders-1458484291

I do my test on the bench before inserting in case.
