Power supply making pc turn on and off constantly

[JaayOCE]

I just installed a new coolermaster mwe gold 650w. My pc motherboard lights flicker and the NZXT kraken water cooler logo flickers and I can hear the water pump turning on and off as well. And when I click power button on the pc it won’t start.

So remove hard drive cords. Gpu cord. Fans cords? And leave the 24pin, cpu cord. ?

What are your system specs?
Did the system previously work with a different power supply, if so, which power supply was it?

Yes

Yes I just installed this new power supply I had lying around because I was going to give my my old one to my friend. My specs are: i5 6400, GTX 1070. Gigabyte B150m d3h MOBO. Crucial 240gb SSD. WD Blue 1TB. NZXT Kraken x42 cpu cooler. PC worked fine before I installed new PSU. Old one was a BeQuiet Pure power 9 500W.

Tbh this BeQuiet psu was more than enough for your specs, any reason why you swap it??

My friends pc stopped working so I had the new psu I just installed put into my pc and then I gave him my old one to see if a new psu would fix it. (But i think it’s a motherboard issue.) He put something about his pc on the cpu, motherboard, memory topic.

What I would do is take out all components from case, try to test it outside ( mobo box is ideal for test bench), connect only what’s necessary (24pin, 8pin) see if that works, if tes start adding other components (btw start with one stick of ram).
