Hello,

I currently run a Litecoin mining rig with 2x Radeon 7950 GPUs. I have the Gigabyte version specifically (they are not undervolted.... yet!)
This is the model: http://www.amazon.com/Gigabyte-Mini-Displayport-PCI-Express-Graphic-GV-R795WF3-3GD/dp/B007581QHG/ref=sr_1_1?s=electronics&ie=UTF8&qid=1389496056&sr=1-1&keywords=gigabyte+radeon+7950

However, I was wondering if my PSU could handle another 7950, R9 270x or 280x. The 3rd card would probably be Gigabyte or Sapphire no matter which card I add.

Currently, I have the 1000 watt EVGA Supernova.

Let me know what you guys think- thanks in advance!

Why? Because he wants more Litecoins. It's not a gaming box.

Yeah, that PSU will do the job.

I was just looking to add more Kh/s to my Litecoin mining rig, and wasn't sure if the PSU could handle a third card. I hear that the R9 series is more power hungry than the 7950s, so I wasn't sure if all of these cards could be viable options for the third GPU.
Do you know of a good PSU requirement calculator that I could use for future reference? I read in a different post that some good ones do exist, however none were specified. That may help me in the future as well.
Thanks for the quick response, too!
