@ikir: yes Smile

It actually uses 225W. The Dell DA-2 delivers 220W. 10 is used by the enclosure, that remains 210W. Under very heavy heavy load I've seen signs of under power (black squares, comet trails while dragging windows, etc) but it was very stable and silent.

While it's possible to run the GTX 980 with an DA-2 power brick, I'd recommend using a more powerful PSU. I've ran into hard crashes using the DA-2 with GPU rated 150W or more.

Do you think the GTX 970 could run into crashed under heavy load? @itsage

At least my MSI GTX970 Gaming 4Gb OC hasn't crashed yet while doing some editing in FCPX, gaming Counter strike with max settings or running heaven, valley and Luxmark benchmarks. I don't know if those qualify as heavy load 🙂 What I find a bit funny is that GTX970 is not able to run 4k videos in quicktime without stuttering, but 3840x1600 plays still just fine. Maybe that is just a driver issue. Intel Iris 540 plays 4k without an effort.

Pairing the GTX 970 with DA-2 should be fine.

Which Thunderbolt 3/2 adapter did you use? Works with windows???

Thanks

This implementation uses an Apple TB3 to TB2 adapter:

 I've had to underclock and underpower my Zotac GTX 970 slightly (90% power, -75 mhz core) to make it stable enough not to trip the circuit protection on the DA-2. It was mostly stable at 100% power and stock clocks but sudden explosions (intense graphical effects) onscreen would shut down the DA-2 and crash the drivers. I suspect this was an overvoltage problem when the card needed to quickly ramp up the boost clock. (See the discussion of DA-2 power draw in the power subforum.) Slightly underclocking it keeps the clock steady at ~1200 mhz, with no boost and hence no overvoltage. YMMV depending on the particular power target and limit set by the vbios in specific cards, but anything >150W could potentially run into this problem with the DA-2.
