Can I run a 1060 3GB Gaming card and a 1060 6GB OCV1 at the same time?

I have a 650W PSU, with an i7 6700k, 16 GB of DDR4 Memory, and I recently switched from a 1060 3GB Gaming to a GTX 1060 6GB OCV1. I love the performance on my new GPU, but I've asked all my enthusiast friends if they wanted the card for a build. All of them saying no. (Wonder why, with 3GB of VRAM..) Now, I really want to put in both cards. However, I've noticed I'm a bit out of my league here. Can my PSU handle it? If so, will I need any other products to make it work? I'm also concerned about the size... the 3GB card is huge and I don't want to have to put my 6GB into the secondary PCIE slot for speed reasons. I figure I won't be able to put the 3GB into the secondary PCIE because it might be obstructed by my HDD. Sadly, I can't check right now, as I'm out and won't be able to get home for a day or two. Another issue is thermals. I have plenty of fans on the front and back of my case, but I don't want anything getting too hot. (My room doesn't get good AC coverage, I'm the farthest from the AC unit in my house.)

Thanks in advance.

It depends... Generally the reference GTX 1060 has a TDP of 120 watts. Two of them would be double that figure, which is equivalent to a GTX 1080 Ti in power usage; 250 watts. But my question to you is what is the precise manufacturer and model number of your 650 watt power supply. My answer is contingent on your response.

What I would do:

Sell both GTX 1060's, and buy a single GTX 1070. The 1060's do not support SLI.

I have to agree, if you need more performance, why are you messing around with 1060s? Why did you buy a 3gb 1060?

If you're new to PC gaming, one good card is better than two lesser cards in most situations for most people. Even then, the people who do SLI or Crossfire and benefit are the ones who plan for it. Just having an extra card laying around and deciding to combine it with the new card doesn't really work.
