4 Pin ATX to 6 Pin PCI-e

[carlosb]

I have 2 ATX 4 pin power connectors like these ones:

that aren't being used in my build. So my question is pretty straightforward.
Is there any way that I could use these connectors to power a, for example, GTX 560 Ti at all? I already have a GTX 560 Ti and looking to upgrade my system so that it supports SLI but I don't want to spend on another power supply since mine is already 850W.

I apologize if this wasn't posted in the right section.

What is the make and mdel of your PSU?

Normally Genuine 850W PSU has 4 PCIe power connectors.. What is your psu model?

uhm, you said ATX power conector, 4+4pins... as shown in the SS... dude, those are CPU 8pin conectors,they use 4+4 for older mobos... and newer uses the 8 pins. i wouldnt like to see what happen if i conect them in a Video Card, dont you have at least some molex conectors free? i mean you could instal your GPU with them using a molex-pcie conector, like this one

Dot not plug your mobo with those, i really dont know what would happen, but im alsmot certain that those would fry your GPU...

I would not risk running SLI with a shady "850W PSU" without at least 4x PEG connectors.

Here is the complete guide to connecters from your PSU to the GPU's. I hope this helps and Good luck to you.

On the box it says Pixxo Transformer and it actually has the 80 PLUS badge. 😱

I have 4 molex connectors free, but I will be using them soon for some fans. However I'm thinking of getting the ASUS P8Z68-V/GEN3 SOCKET 1155 MOTHERBOARD which has 5 connectors for fans.

It seems too much of a hassle and expense upgrading the whole build for SLI support so the "futureproofness" only lasts about 1 year to 2 years. I guess next time I'll have to save up and buy one expensive build right from the start. 😀

They do make molexs that do a"Y" config, so you can add fans as well.

Yes but doesn't that half the voltage going to the fans? And BTW I read the guide you posted so I'll choose you best answer but tomorrow, getting kind of late for me. 😴

It lowers it a little but you will not notice anything. I have 7 case fan's and 3 MOBO conecters for the 3 fans. The rest are done through either molex or though my fan/temp controler.
