I'm having trouble with my new GPU that I just received. So I've decided to upgrade my PSU and my GPU to play BF4. I used to have 550ti with a 500w psu. I've ordered ZM600 LX and HIS-R9 270Z. And I've replaced the parts accordingly. I used to have 550ti with a 500w psu. The PSU works just fine with the rest of the build the same(the GPU being the 550ti) But when I have the new GPU in the build, the main board doesn't boot up into it's bios... what I'm saying is my screen would show the PEGATRON logo on normal boot, but it doesn't with the new GPU in. I've done a couple of tests which could be pretty dangerous to the GPU which was plugging in only one PCI 6pin cable instead of two. The funny thing is that the mainboard seems to be working with only one of them plugged in. I'm guessing the problem has to do with the way I have the PCI 6pins plugged in. zm600 lx has this string of 6pin cable coming out from the box with the other 6pin coming out from the end of the the 6pin from the box. Will getting a converter for PCI 6pin and have it plugged in from one of the 4pin solve the problem? Or is it just my motherboard doesn't support PCIE3.0 of the 270x when it supports PCIE2.0 of the 550ti... It's really out of my knowledge... and I need help!!! All help will be appreciated!

I'm currently away from the computer and not able to try it, I will though once I get home. But does the driver has to do with the mainboard not booting up though?

Can you guys please check if the PCI 6+2 pins of the PSU(ZM600 LX) compatible with the GPU(HIS R9 270x) which requires two 6 pin of PCI? I'm guessing this is where the problem is coming from...
