New Build wont powerup

[Nilkin]

Hello, I recently just built a new pc for the first time, im not super tec oriented or anything and I am having an issue trying to poweron my new computer for the first time. I believ I have everything plugged in properly and am having trouble trying to get it to boot up for the first time. It does not seem to be an issue with the powersupply because the test fan seems to work properly and the motherboard appears to receive power. Whenever I turn on the powersupply and hit the power on button both the LED's on the front fan, and the fans themselves turn on momentarily for a brief second then stop. I dont really know what the issue is. Both the 24pin power cable and 8pin+ 4pin cpu power cables are connected. My build is a Haf 932 advanced full tower, MSI X99s SLI kraits edition motherboard, corsair 850i platinum modular power supply, I7 5820k processor, EVGA 980ti superclocked+ Acx 2.0+ Backplate, 16gigs of DDR4 corsair vengence, front 240mm case fan, back 120mm case fan, and side 240mm case fan, 1tb WD black HDD, and a 250gb samsung SSD. Does anyone have any ideas as to what the issue could be or how to fix it? What to try?

CPU might be overheating?

Reapply thermal paste.

 

Faulty hardware?
Try using the parts in a working system.

 

Double check all the connections and watch video guides on how to build a pc and see if they do something you didnt.

Made sure the reset button is connected. I had the same problem when I did my first build.

How do you know its not the PSU without swapping it out

[gabe927]

Try swapping out the PSU, otherwise it could be the motherboard or the processor.  If you can, try using each of the parts with different parts, that should narrow down what the problem is.

Ive triple checked all the connections, its kinda hard to find a video with the exact parts as well, the radiator came with thermal paste already applied as well. reset switch is connected + to + - to - properly as well. I dont have any spare cpu to try.

[gabe927]

Could you at least try the PSU on a different computer?

[Nilkin]

Ya, ill try my 640watt power supply on my current computer.

I sawpped the psu and it still did not power up, same issue.

[gabe927]

All I can say is that it could be the motherboard or the processor.  Its most likely the motherboard, but I would try calling MSI or Intel support, or bring it to somebody who can take a look at it.

[Nilkin]

Thanks, I have somebody who can look at it for me and I will call both troubleshooting groups to see what the issue is, its a bit dissapointing trying to get it to start up and it failing.

[Nilkin]

Turns out the PSU was dead, it also took a motherboard, and my HDD. I ended up having to replace all three items, and the system works perfectly now, thanks for the help .

Did you rma the motherboard or did you have to buy an all new one?

[Nilkin]

Ya I had to rma it, ended up sending my processor back too and got a i7 6700k cpu, and z170 deluxe by Asus. It kinda sucked because it also fried my cd drive as well making it a pain to install windows. The system works perfectly now and runs at an average cpu temp of 34degrees Celsius when under load.
