Just searched this forum up and down but couldn't find the right answer:

I had the chance to get a "cheap" RTX 3070 and have a ADT-Link hooked up to my HP Elitedesk Mini via M.2

I'm a little bit concerned about the power consumption. 

 

- The PSU for the Elitedesk delivers 90 watt power.

- The CPU consumes up to 65 watts of power.

- The RTX 3070 has a TDP of 220 Watts.

- Founder's Edition so one 12 Pin to 8 Pin adapter.

- 8 Pins provide 150 Watts max.

 

In a "normal" setup the 3070 could get the remaining 70 Watts through the PCIE-Port but I can't power a GT 1030 (which has no addditional power inputs) through the board + ADT-Link. There's just not enough power coming from the board under load if the CPU is going up, too.

 

So I presume that I have to limit my 3070 to a 150 watt intake?

Alternatively:

Could I use a 12 Pin to 2 x 8 Pin adapter (300 Watt total) or would this fry my precious new card?

 

Thank you! Smile

The ADT-Link R43SG uses an independent ATX or Dell DA-2 PSU to drive the slot (75W) plus any additional PCIe power plugs of the video card.

See this build of mine to see how two 220W Dell DA-2 PSUs were used to drive a GTX 1080 Ti:

Thank you! 

Ok I didn't know that the Dell DA-2 PSU can deliver power to the board and the GPU. I use one to power the board.

I made a mistake and not logging any power consumption with the GT 1030 and if this was the real reason my system crashed under load.

So in theory it would be enough to use a Dell PSU with the ADT-Link + the 3070 (I know that's a bad idea to max out the 220 W of the Dell ...)? No additional power would come from the Mini-PC?
