Help me figure this out?

Hey all, so my family is on vacation for a couple of weeks, so I wanted to try out my dad's system, which he was okay with of course. Anyway, I have a GTX 760, he has a GTX 760. The difference is that he has a 4820K and I have an FX 6300. I want to throw my GTX 760 in his system and SLI them for the week, just to see the performance gains and stuff. My friend is coming over in a bit to give me an SLI bridge since I don't have one for some reason. The problem is, his PSU is (I believe, but I probably have to check to make sure) 550W, and mine is 400W. Is there a way I can use both, one to power the system and the other to power the GPUs? Something pretty easy to do that won't require rebuilding everything, as this is just to test out and see how everything will run. I will be throwing my SSD in his system as well so I can use my games and all, so will the licensing not work? I am Windows 10 Build 10240 (RTM). I know the system will start up and all, as the Nvidia drivers apply to all GPUs. Thanks!

 

And I will put it back nicer than I found it. Probably do him a favor since it's never cleaned.

 

Edit: Should post both system specs, shouldn't I?

 

Mine is my signature.

 

My dad's:

 

4820K

Seidon 120M

Gigabyte X79-UD4 (I think)

16GB DDR3

I will be using my 840 Pro SSD

MSI GTX 760 (reference cooler)

some iBuyPower case

some 500-550W PSU.

Whelp, figured it out.

 

 

Had to use the paperclip trick to get the second PSU to power on. But the system recognizes everything, although Windows 10 isn't activated anymore since I changed the mobo. Guess the Insider license is tied to your motherboard as well. Still waiting on my friend with the SLI bridge, but going to see how it performs soon.

Wow you guys really don't want to help today.

Well, it works. Kinda. SLI on Windows 10 is shit, or Nvidia has completely dropped the ball on the last few drivers. My friend, who has a 690, had the same issue where BF4 would crash with a DirectX error on Windows 10, so now I'm assuming it's because of SLI. The FPS increase was very dramatic, on Siege of Shanghai it would increase from an 80 avg to a 130-140 avg, even with the map being very buggy and awful to me. I wouldn't recommend it though, I see what people say when they say a single more powerful GPU is better. Plus I accidently unplugged the PSU that was powering my ASUS 760 and the whole thing fucked up. Anyway, just wanted to see what it was like.
