Title: 13 GPU Rig with 8+6 PCI Power causing problems - Adapters? Molex? Post by: cccomputing on December 10, 2017, 10:17:03 AM Hi everybody!
Im building a 13 GPU Rig currently and bought two Corsair HX1200 PSUs. The plan was to put 13x GTX1070 into it. Then i had the chance to buy 13x GTX1070Ti for a very good price and i did. I didnt think that the 1070Ti would come with 8+6 Power and now i dont have enought connectors to power all 13 GPUs. The GPUs do not turn on when just using 8 pin power. Not i am thinking whats best to do. Currently im thinking about 2 options: 1) Buy a 6 to 2 * 6+2 Adapter to split my eight connectors per PSU to 16 to power eight 1070Ti. 2) Connect a TwoMolex-to-PCI6 Adapter but just connect one Molex per Adapter. I just want to provice a few watts over those connectors since the 8pin should be powerful enough to deliver all i need. its just to make them turn on. Is one of those ideas a good idea? Or better buy a third PSU? Or maybe you even have other ideas how to handle the situation? Thanks for you ideas! Title: Re: 13 GPU Rig with 8+6 PCI Power causing problems - Adapters? Molex?
