I have no idea why its not working my PSU should be enough, the problem happens on both pci-e slots. It's either the PSU or the GPU, when I install the GPU the fans are spinning, but when I check the device manager using integrated graphics there's nothing there just Intel HD 4000.

I would really like some help,

my specs are:
CPU: I7-3770K 4.2 GHZ
MoBo: MSI Z77A-G45
RAM: 8 GB Corsair Vengeance Blue 1600 MHZ
SSD: Samsung 840 120 GB
HDD: 1 TB Seagate Barracuda
CPU Cooler: Zalman LQ 310 Water Cooler
Case: Zalman Z11+
Sound Card: ASUS Xonar DX
GPU: Gigabyte GTX 770 WF3
PSU: CM Extreme 2 725w

I use dvi connector on the gpu.
