GTX 560 Ti SLI...on 750W?

post #1 of 15
Thread Starter 
Hi,

I'm thinking of adding another GTX 560ti to my current one. I've never done SLI before, so I'm curious whether I would run into any serious cooling or power problems. My current GTX 560Ti runs idle at about 40C and 55-60C on full load (with fans manually bumped to 80% at load.)

I have a Corsair TX 750W PSU. I really like it and don't really want to get another PSU, but I'm curious if that will be enough power for 2 560 Tis? I don't plan on OC'ing the GPUs, but I'd like to be able to OC the CPU.

THANKS!

Your 750W should be fine. Each card only draws 170W anyway.

Wonderful. Thanks very much.

Think I'll run into some cooling problems? I'm still concerned about keeping everything nice and cool, but I'd imagine it's somewhat inevitable to have a warmer environment with the 2 GPUs marching along.

You should be fine as long as your case has decent airflow. Also if you can space the cards out so they have room to breath.

Not sure how many PCIe slots your mobo has but if it has three, use the first and third so your 560s can remain cool.

You have more than enough power. Those cards run cool and as long as your case has decent airflow you will be just fine.
