high-end PSU recommendation?

[ultra99]

Looking for a high-end PSU. According to the info provided, should I go with a 1000w or 1200w psu? I'm also aiming towards Titanium or Platinum.

What do you guys think of this: be quiet! DARK POWER PRO 12 1200W US 80 PLUS Titanium https://www.canadacomputers.com/product_info.php?cPath=33_1938&item_id=171981

 

PS: i'll have both gpus in the system, one for video production the other for linux/macOS.

You could possibly get by with a rmx1000w unit but maybe for saftey the hx1200.

 

I don't know what psu you linked as the link doesn't work for me.

Are you getting both a 6900 XT and 3090, or are those your two options? For just one or the other, 1000 watts is fine. Not sure why you would get both, but if they're going to be working hard at the same time, along with the CPU, then a 1200W is justified.

I never saw someone is using NVidia and AMD card at the same time with no issues

I'd really like to see his rig and the cards,who knows maybe he did crossfire

I've done it before myself, with a junk rig for f@h. I find that the trick is the "less important" card should stick with the automatically installed drivers from windows updates, and the primary card should have its brand appropriate software suite

DPP12 is more or less the third-ish best PSU you can get, so yes, its good. And wattage wise its fine.

Some render software can leverage cross GPUs. Of course if you have 2 drivers, 2 cars is fine. One program with one GPU, one with another.

 

But it's just conjecture. OP hasn't said one way or the other.

Yes, one program for each.

AX1600i is the best, and 2nd i cant really pinpoint. It also depends on how you are counting.
