So I just bought a new nighthawk 117 full ATX tower and swapped everything over from my Nzxt guardian. Everything worked absolutely fine before the swap now I'm not able to get a full circuit of power through the system. It will show a blink of LEDs the system fans PSU fan and GPU fans will make less than half a turn and all power is lost. Pressing the power button after that does nothing, I have to turn the I/O switch to get it to do that again but it's as far as it will go.

I have all correct standoffs in place (full ATX) and no extras underneath the board. All wiring is connected correctly and in place very well nothing is loose. So I figured that it was a faulty case right out of the box, swapped back to my guardian and viola now it's not working! Doing the same thing as before! I'm thinking I may have fried something by accident (maybe the motherboard) but I was very careful swapping the stuff around, used antistatic bags and everything. I ran all of the test checks taking out graphics card then a stick of RAM etc. Each time I hit the power button though, it does the same thing without a hitch. I am really at a loss here.

Thanks in advance for any help provided. Don't hesitate to tell me the small stupid stuff I didn't think about checking, as anyone can miss a minor detail.

first things first, you probably already know, but just in case, make sure the small power cable is on the mobo to, not just the big one. and yeah, anyone can make a stupid mistake not hooking anything up, such as forgetting to hook my hdd up and trouble shooting for hours and hours before realizing it XD

Yes that is what I was thinking. Power supply is new but also tested and running great in my old build. I literally just got all of the components three weeks ago, put them in had them running so I know how it was supposed to be wired up. It's just once I transferred cases I've had this problem

Both were in the same build running great. I checked both sides of the motherboard they look good no missing, bent, or rounded off nodes no burn spots. I even took care of it when transporting using the anti static bag. CPU looks fantastic I just took it out and re applied thermal paste and checked the pins they all look good. I hope none of those fried because I spent good money for them.

That is exactly what I am saying! I've literally redone everything now. Reset ram, CPU, standoffs, PSU and tested with jumper that came with power supply. Going to just hook up the things I have e to have to boot the system then start adding things to see what it is. I'll stay posted

Figured it out. Had a 4 pin molex from the PSU that looked like a fan wire. Unplugged it and it booted right up. Also happen to be what was wrong with another build I was working to surprise my brother with. Thank you for the help
