Title: 1000w for 3x r9 290 Post by: Starscream on January 19, 2014, 05:28:40 PM As the title implies: Will be able to power 3x r9 290 with a single 1000w PSU? I can get this Tesla R2 1000W (http://"http://www.fractal-design.com/home/product/power-supplies/tesla/tesla-r2-1000w") for rather cheap.

So I'll be buying a 1000w after all.https://bitcointalk.org/index.php?action=profile;u=189723;sa=showPosts how do you do cooling? airflow? i assume its not a good idea to use a 1000W power supply.
