Default Re: Molex connectors!! 6x Hard Drives and 2x GPU's

From memory, those 5770s have two 6-pin PCIe power connectors each? Both of which need to be connected otherwise they won't work properly. I'm not sure that leaves you many options. An additional power supply is probably the go. Another option would be to replace the two 5770s with a single, newer, more power graphics card. There are plenty of details around about running something like an RX580 or RX7970 in these machines with a HDX card. The 7970 in particular is readily available, flashed for OSX use. They also have the benefit of being about 350% to 400% more powerful than a single 5770.

Just a thought.
