@jaslion I need 1060 for CUDA computing on windows and r9 280x is spare GPU of a friend, so it wont cost me anything unless I damage it. I am currently not able to afford a new PSU that is why I am looking for a solution like this Also Sapphire r9 280x card that I borrowed only has 1x 6pin for power so I am able to plug all GPU's with one PCI-e adapter. However as you said, VS550 being a low tier PSU scares me a bit

Hello, I am planning to setup a hackintosh with my PC but latest versions of MacOS does not supports NVIDIA cards. So I am looking into possiblity of installing a secondary GPU to get some performance from the installiation. But here is the problem. My PSU is a bit underpowered and I want to hear your opinion on the matter. Here are the specs; PSU: Corsair VS550 CPU: AMD Ryzen 2600x GPU: Asus Dual 1060 3GB OC RAM: Adata 2x8GB 3000MHz MB: Asus Strix B450-E Gaming Cooling: Corsair H100i Platinum, (Total of 6 fans on case) Storage: 1 x 2.5" SSD and 1 x 2.5" 5400rpm HDD From online power calculators, it seems like this system consumes up to 400W of power and I want to add another R9 280x to this system. Which brings up total power consumption to 650W at full load (even though I probably cant even hit that) The PSU only has one PCI-E power cable with two connectors so I will be plugging one end to 1060 and other one to 280x. What happens if PSU gets overloaded ? Is there potential to risk the hardware or does it just shutdowns the computer. Is there a way to force D3 power states on both Windows and MacOs ? So that I can turn off 280x while on windows and 1060 while on MacOs. I am aware that the setup becomes a bit getto with this kind of configuration but as I said I would like to hear your opinions on this topic.
