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.

thanks for the reply so what kind of wattage would i need to fuel a 1070 mini?

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

Give your Node Pro a second Thunderbolt3 controller for reliable peripherals by re-using a TB3 dock (~50$).

hey yukikaze yea i been following you and enjoy for a while on here before i got an account awesome info but i was just trying to use that dell 6RTJT power supply because it was slim and a little nicer then the big brick DA-2 lol

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 🙂

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 .

Output: 19.5V 12.3A 240W

The adaption of the barrel plug is one issue. The bigger problem is driving a 12V input with a 19.5V source. Pls check your enclosure’s manufacturer to see if they are using voltage regulation to allow higher source input voltage.

Then what are you going to do to split off power to supply 12V PCIe 75W/6pin or 150W/8pin input power?   I assume you want to drive a video card that requires > 75W power to drive it.

The Dell 6rtjt AC adapter is 19.5V. It is unsuitable for use with any of these TB3 enclosures requiring a 12V input. As from here . Will Kareon Kables compensate you for a damaged video card and/or enclosure if you use their adapter that simply allows physical connection of 12V devices with a 19.5V power source?

Voltage regulation + power splitting is not efficient and it is not easy for the money you will spend you can embed a psu for car-puter  (the most expensive and tiny psu) lol

@eight bit hero, I have deleted your Kareon Cables Dell 6rtjt passive cable link because they are falsely advertising it as a 12V power source when it is in a 19.5V source.

That being necessary to prevent unsuspecting users damaging their video cards and/or eGPU enclosure with this 19.5V AC adapter + converter cable which expect a 12V power source.

now i get what your saying lol i wasn't understanding what you meant 

so the da-2 is a 12v brick correct?

Yes. Dell DA-2 is a 12V power source.
