New build PC won't start!!!

[Bas Uitermark]

Hey guys,

 

So straight to the point, I finally built my pc today. When I was finally done I started up the pc, it was on for a split second and then stopped. I checked if my 24 pin, 8 pin and 6 pin were correctly in place and if my power switch was in the correct place, but still nothing.

 

I really need some help here!!!

 

Thank you,

Oh sorry man, I rushed a bit there.

 

CPU: AMD FX-8350 Black Edition

COOLER: Phanteks PH-TC14PE Black

MOBO: MSI 990FXA-GD65 

RAM: Corsair XMS3 2x8GB DDR3 1600

GPU: XFX R9 280X 3GB

CASE: Fractal Design Define R4 Black Pearl

SSD: Kingston SSDNow V Series V300 120GB 

HDD: Seagate Barracuda 7200.14 ST3000DM001, 3TB 

PSU: Seasonic M12II 620W

Wait the GPU is a XFX R9 280X

That big ass plug that goes into the motherboard, make sure that's in real solid, for months I thought mine was and it wasn't, I kept getting crashes and it was simply that the plug was losing connection where I hadn't forced it in enough. You can't be gentle with everything.

Make sure that the mobo is not touching the standoffs causing it to short out. This is a similar case that I had and needed to put rubber grommet s on the standoffs so that the back of the mono pcb was not touching either the standoffs or the back of the case. I know you don't want to do it but assemble everything outside of the case and see if it power up. Please keep us posted so we can try something else.

[Bas Uitermark]

I took it out and put it firmly back in to place, but I still got nothing.

[Bas Uitermark]

Indeed I don't really want to do that... But I will give it a try, I'll be back in a hour or so guys!!!

i see your problem

give me 2 m

 

-- edit --

 

if your pc is all new parts go to the store exchange your psu while its a great brand

 

Radeon R9-280X - 30A and a 550W psu minimum

 

your psu

• ATX12V V2.3 / EPS 12V V2.91
• Modular
• 80 PLUS BRONZE Certified
• 100 - 240 V 50/60 Hz
• +3.3V@24A, +5V@24A, +12V1@24A, +12V2@24A, -12V@0.8A, +5VSB@2.5A

i would get a single rail psu even though you have on the 12v rail a total of 48 amps its devided in 2 so it could be your problem even though tecnicly it should work

hope this helps

Oh yeah....Make sure the the 6 or 8 pin cable that is normally at the top left of the mobo is plugged in. I did a build and forgot to plug it in and was getting the same issue as you.

[Bas Uitermark]

@jinroh10 THANK YOU MAN!!!! Indeed it shorted out on the case, everything worked perfectly outside the case, now I need to figure out how prevent this from happening inside the case. @phoenixto I think my problem is solved, if any new problems occur I will get the new PSU.

 

Thanks you guys!!!

Thanks you guys!!!

Make sure you have every single standoff securely put in and check if your board is touching any metal around the case

[jinroh10]

Awesome...find some rubber grommets to put on the stand offs and then place the mobo into the case, you should be fine after that. I'm glad that worked...please keep me posted.

[Bas Uitermark]

So here is an update guys. I put everything back together into the case (this time checking if the standoffs were securely put), checked all the wiring and finally it al worked. I had no trouble at all, Windows 8.1 was easily installed and everything is correctle working now.

I would like to thank you all for your support, I wouldn't have figured this out on my own earlier today.

 

Thanks guys!!!

[jinroh10]

Your very welcome....glad I could help. Have fun with your new build.
