sli gtx560ti's max power 170 + 170 = 340W/21A Both under load. the OCZ is 650W it is capable of sli/crossfire out of the box it has 46A on the 12volt rail. it will power with no problem.

You can purchase a little adapter for the power plug. Most common one is molex. Just make sure the ratings match up. For instance, single molex is rated for 60 watts, pcie 6 pin is rated for 75 watts, so get dual molex to 6 pin (I guess in your case you would need two of them). Etc.

You need a bigger power supply to add a card. Your system with an additional card would be pushing apx. 619W. A 30% buffer is ideal, so a 750W would be the minimum that I would shoot for. If you have trouble finding one with 4 PCIe 6pin they do maka SATA-PCie convertors.
Power consumption figured by imputing parts list at PC part picker

one card needs 6+6pins.

if your psu only has 6+6pins. you can get a molex to 6+6 pin connector.

that is 100% false. this build with sli gtx 560ti's is around 460watts.

Ok, so I need to get 2 molex to 6 pin adapter.
However I only have 3 molex connections left, can I get SATA power to 6 pin as I have a few of them left. Thanks sooo much, without this forum I wouldn't have the computer I have now!

thats the limited edition gtx 560ti. the normal gtx 560ti is less power consumption 170watts. the limited edition is 230watts.

You can convert SATA to molex or SATA to 6pin PCI-E but not sure for last one

Best solution

April 13, 2014 4:11:26 AM

yes. as long is the gpu is powered by two 6pins you're safe.

April 13, 2014 4:13:01 AM

but be aware!.these cables may not be safe depending on the form factor because some people experience melted rubber or burnt/melted plastic on the molex/sata.

Ok thanks, I just need to make sure I get long enough cable's to reach to my card.

WAIT.you must get a brand that has the same memory. getting a slight lower memory will make performance even slower on sli. get a 2GB.
