Hi !

I bought a Gigabyte GTX 1070 Windforce OC 8GB, but it failed miserably. As soon it arrived, I put it my motherboard Gigabyte B75M-D3H/Intel I7-3770/Win7 , replacing a GTX 650 Ti Boost (from Gigabyte too). It just won't boot. Worst: my mobo just died ! No video sign, no usb, nothing. Double check cables, clear CMOS, (Bios was the latest one, I check it before crash). Drop dead. The only sign is the CPU fan starting when power on, but it doesn't power off, unless I unplug the power force.

Then I try another motherboard (borrowed from my wife's PC), this time in a Gigabyte Q77M-D2H - Intel I5-3470. Pass boot, but freeze at Win7 start. Try safe mode, it runs, but don't solve: it freezes at normal win7 boot or at boot splash screen. I replace the brand new GTX 1070 by my old GTX 650 TiB and it runs gracefully, like a boss.

Tried an ancient, already retired, Gigabyte GA-G31M - Core 2 Duo: boot ok, ran Windows 10 with generic driver,etc. But it is pretty old and slow system, no plan to use it or even update win10 in order to install new video drivers.

Are you guys facing problems like this ? Is this a known issue ? There are safe brand/model of GTX 1070 ?
Bitter note: This video card cost to me ~ US$ 625,00 (Brazilian R$ 2.000,00) plus a new motherboard.

Specs:
CPU: Intel I5-3570 / I7-3770 (stock clock)
GPU: Gigabyte GTX 1070 Windforce OC 8GB (fail!)
Gigabyte GTX 650 Ti Boost (runs like a boss)
Mobo: Gigabyte GA-Q77M-D2H (alive)
Gigabyte B75M-D3H (dead)
Disks: Kingston SSD 240GB / 2x HD Samsung Barracuda 1Tb.
RAM: Kingston 16GB 1600mhz
PSU: C3Tech-500W plus UPS TS-Shara 1200VA

 
Thanks for you replay!

I'll try a bigger PSU, asap! Perhaps a EVGA 600W.
But this same rig runs the GTX 650 ti Boost (134w max), not far from GTX 1070's 150w.
Some online PSU calculators pointed that my system requires a PSU with 356W or 600VA ( http://outervision.com/b/PGXKIP ).
Calculated power consume are :
*10,0A at +3.3V
*10.2A at +5.0V
*22.6A at +12V

Nevertheless, my actual PSU claims is has
25A/22A/38A to +3.3V/+5.0V/+12V.
It should be enought. 🙁

SOLVED !

Just return the GTX 1070 and get my money back !
I just give up about this ridiculous expensive upgrade (VGA + burned mobo replacement + huge Power Supply Unit + new powerful UPS + what else more?)
I'll stick my system as is - good enough for me - and wait until those video cards and PSU stops crashing and both becomes dependable and reliable !
