Update:
Received the cable last Monday at night. It's the exact same cable with no change in the length or the type, have been trying the cable for 2 days. First time it didn't boot, so I tried to move the cable slightly out of the PCI Express slot and it worked with very very low FPS. Didn't even boot some games. Tried again by moving it out again and it worked but with beeping sound that the VGA has problem. I ignored it and made some tests and it worked flawlessly. And left the PC for 2 days working without rebooting or powering it off as I was already downloading some stuff and also I was afraid that it would do it again.
Restarted the PC yesterday night and it didn't boot since then !!! giving No Signal error on the monitor screen. And it only boots when I take the riser cable off and connect the GPU directly to the slot or when I boot with the integrated GPU.
I tried not to bend the cable and to not to let the shield out of the sockets.
I'm fed up with this issue. I only bought the case to have the GPU front standing as it's too heavy and causes the GPU to sag (Zotac Amp! Extreme GTX 1080).
Have anyone ordered other cable from Thermaltake or any other type like the premium one ??? And how much for the extra fees.
I really like the case as it has many options, but the cable is really destroying my image to Thermaltake.
