Recently I bought a EVGA 750BQ (https://www.evga.com/products/product.aspx?pn=110-BQ-0750-V1), with the idea of powering 3 gtx 970 g1 gaming which is an specific 970 model that uses 2 power connectors (one 8 pin and one 6 pin) instead of one. When we talk about power, I am totally sure that 750w is enough to feed them, but I am really worried about the power connectors.
The problem is that I just noticed this psu has 3 PCIE cables and 5 molex. I was planning to connect each gpu 8 pin connector to one of these 3 PCIE cables, and I was planning to use 2 to 6 pin molex adapters to feed the 6 pin gpu connectors. Since the motherboard I bought has one extra molex connection I believe I would be able to solve the gpus power connectors problem, but is this safe? In this example I would have to power all my riser slots using the infamous SATA to molex adapter that comes with it.
By the way I cannot plug the PSU in the 970s and test it by myself because the motherboard for this system will probably be delivered where I live only after Christmas.
I really need some help here, because in case I find out that the PSU I bought isnt going to work I need to return it to the seller as soon as possible and buy one that actually works
return the psu today
