PC running but GPU isn't

[Nerion]

I just finished building my computer and everything is running great. The only problem is that the GPU is not powering on. Other than that, windows runs great, fast, installed everything. I don't know what the exact problem is.

 

This is my build: http://pcpartpicker.com/p/HCp7Vn

 

I plugged in both 8 pin and the 6+2 pin without the +2 pin into the GPU to power it on. Both cables are connected to an 8pin in the PSU. I also tried using the 1st and 2nd pci-e ports and it still does not power.

try using different psu ports if it is a modular unit

stupid question, but did you make sure you are using the pci-e 8pin, rather than the cpu 8 pin?

What makes you think the GPU is not powering on?

The 8 pin cable plugged into the GPU is powered by a 6+2 pin in the PSU and vice versa.

Had a hard time powering it on at some point couple days ago. After trying various connections, at one of many tries at powering the system, when turning the pc on, the system itself and the geforce logo lit up for about half a second and then shut down instantly. As I was looking at what the problem might be, I got a very very slight smell of burned plastic/material or something of that nature. Thats why I am wondering if the GPU works or not.

If its a 6+2 then its meant for the gpu.

 

Try running a stress test on the system without the gou to see if it crashes. If so, then the PSU may be at fault.

The EVGA NEX series isn't known to be the best, but I would try RMAing your GPU; then keep an eye on your power supply.

If I run a stress test, and it crashes, is it 100% the PSU's fault ? Why is it powering all my system but not the GPU?

Already tried.

It would likely be the PSU if it crashed when the system is under load. If it cant handle your cpu + motherboard under load, then it wont be able to handle the gpu.

 

The PSU you are using is of good quality, and 650W is more than enough for your system, so if the PSU is at fault, it would have to be down to faulty unit.

Thing is, I bought this Sept. 17. Which is 2.5 months ago. Ill try to see my options there.

Ill give it a a stress test, you think prime 95 would do? or should I run cpu-z cpu stress test?

Prime 95 should do the trick. Watch out about running it for prolonged periods of time though, I heard it does some funny stuff with haswell chips and power delivery.
