hey everyone

 I'm new to this whole thing so bear with me if i sound dumb lol. i wanted to know if the dell 6RTJT power supply could be modded to work with the akitio thunder3. i have a skull canyon nuc w/ the thunder3 and a i want to use the gigabyte 1070 mini. i just think this power supply us thiner and nice then the hulking DA-2 and the R6TJT throws better power.

thanks

No.

The Akitio Thunder3 requires a 12V power supply. The 6RTJT is 19.5V.

no i understand that i wanted to know is there to maybe regulate the power to go to the 12v and the rest go to a 6+2 pin set for the gpu

Your solution is overcomplecated. It's simplier to redistribute  wattage than voltage because every component  (tb3 board 10w, pci-e line 75W and the gpu itself (depends)) requires 12 V. 

I suggest you to use a small factor sever psu (if you need more than 220w) or the ugly but very efficient da-2.

The stock GTX1070 maxes out at 154W of power-draw (source here). A Dell DA-2 (220W) should do the trick.

Want to output 4K@60Hz out of an old system on the cheap? Read here.
Give your Node Pro a second Thunderbolt3 controller for reliable peripherals by re-using a TB3 dock (~50$).

The Dell DA-2 is quite a brick, agreed. But it is a 10$ brick that powers most video cards and has a lot of people using it (so it gives you a lot of pictures to follow to make the connector), hence the overwhelming recommendations it gets Smile

i can't post the link in here for some reason but the kareon kable has it up on there page 

   

This AC adapter is 19.5V. It is unsuitable for use with any of these TB3 enclosures requiring a 12V input. As from here .
