Can't figure out what I need to get two graphics card powered up.
23 minutes ago, boardy89 said:I've had got a GeForce 970 GPU which I've had for some time, but needed a second card so found the cheapest ebay card which was a GeForce 570, I've realised though my PC doesn't have enough cables to power it and I can't figure out what adapter (if one exists) I would need to power them.
The 970 is powered by 1 single 8 pin which is plugged in via 6 pin PCI-E from the PSU into an adapter to convert it to 8 pin into the GPU.
The 570 however, requires 6 pin PCI-E and 8 Pin power but I only have 2x 6 pin PCI-E.
Can anyone recommend the best way I can power these cards, not 100% sure what the adapters might be called and when Googling all I find is molex power to 8 pin but I don't have any molex power, only SATA power cables.
Bro, if a PSU doesnt have enough PCIe cables, then you shouldnt try and add more with adapters and stuff like that. It most likely wont be able to power them. Just like @Vishera said above.
Also, if a card got 1x6 and 1x8 pin power input, it must be for a reason. You cant just plug in the 1x6 and think the card will still be able to get enough power from just that one. Plus that 6 - 8 pin adapter wont really work unless it got both 6 pin power cables attached. A 6 pin alone only have 6 pins, not 8, where are the last 2 pins suppose to get their power from? (the last 2 pins MAY in some cases just be extra ground contacts, but you should still not use the adapter unless you got both power sources plugged in).
Molex to PCIe power cables are NOT safe in any way either. Dont use them unless you want to fry your system.
And for SLI to work, you need a SLI supported motherboard, a SLI bridge but most importantly 2x of the same GPUs.
If you are NOT after SLI, and just want 2 GPUs in the same system for separate things, you still need a better PSU to power them both.
