What PSU to get for i9 and 4 GTX 1080Ti's...

[eco_bach]

Planning a massive upgrade.
New i9 CPU, 3-4 GPU's...will need LOTS of clean power.

Choice of either Corsair AX1500i 1500W Platinum

or

EVGA SuperNOVA 1600W Platinum

which to get?

(currently have a EVGA gold...I know their warranty is quite good)

 

[S_I_N]

both are solid units. But if I may make a suggestion, it seems you make post after post about is this good or that work with this. Have you tried looking at reviews first?? A lot of your questions I have seen can be easily solved by a quick search and research first.

PSU recommendation for i9 + 4 GPU setup

Hi
Upgrading my setup to support a new i9 7960x CPU (+ Swiftech H240x2 AIO) and 4 GPU's(1 Titan XP + 3 GTX 1080's)
Undecided on a PSU.
I can't imagine a scenario when BOTH CPU and GPU's will be running at 100%, rather I forsee OCing the cpu(so between 400-500W for cpu alone!)
Or
running all 4 GPU's at 100% (gpu rendering)

What PSU should I get? Since I'm air cooling my GPU's heat is also a concern (if certain PSU's give off more internal heat than others)

evga 1600 T2 would be my choice, need to take a peek at cables if all four cards at 2x8 pin.
comes with 9 6+2 pin pcie cables.

Merged yet another set of remarkably similiar threads from Eco...

Anyway, 4 1080s, (not Ti), and an i9 won't use that much power. THey are 165W cards stock. So 640W between them and a mildy overclocked i9 (because you are limited by cooling that CPU), you could easily use a 1200W PSU and still allow some overclocking on everything. The key, like caddi said, is the connectors......... know what your cards need and see if the PSU supports it.

As far as which specific PSUs between the two listed, either or, they are both great and you couldn't tell a difference.

 

[caddi daddi]

those are the only ones I know have the needed connectors native, there may be more.

Are the i9 and MoBo already ordered?
Have you checked the threadripper benchmarks I've linked in your other thread?
Have you checked 7960x vs 1950x benchmarks specific to the rendering software you use?
Have you checked the PCI lanes?

Bunch of questions, but worth double checking: it's quite an heavy investment involved here!

Edit:

One more question: have you double checked there is clearance for the 4th 1080ti with the case you use? Keep in mind that with 4 GPU's in the case, unless you go for FE edition, they will throttle due to temp limits: your case will be like an oven (1200W+).
You can use open bench or watercool all 4 cards (with 12x120 or 9*140 worth of rads)...

 

[caddi daddi]

also, as a rule there is lower gpu load when rendering than something like folding@home.
folding loads my cards at 60%-80% tdp where rendering in blender is less than 50% tdp at the most and tends to the 40's.

Thanks! great questions
In regards to benchmarks, have looked at a ton, and for sim , rendering even the 7900x seems to beat the TR. Nothing specific to software I use (Houdini, Mantra) though there is a LONG thread over on odforce debating the pros , cons of TR vs the 7900x

Interesting article over on Anandtech
https://www.anandtech.com/show/11839/intel-core-i9-7980xe-and-core-i9-7960x-review/4

And yes I am aware I must go with FE if just air cooling.

update, after reading THIS on gamersnexus am reconsidering the TR over the 7960
https://www.gamersnexus.net/hwreviews/3066-intel-i9-7980xe-7960x-thermals-power-review

Confused why so many reviews don't seem to agree when it comes to power consumption tests

My takeaway is that if you don't plan on doing a lot of OC'ing the TR is the better option. If you want THE fastest, and don't care about power consumption and thermals, go Intel.

Surprised by the 100W difference during stock mutlithreaded renders!
Assume I will also have to rethink my mobo choice if I go AMD
Should I go with ASUS ROG Zenith Extreme? Might as well go with the best if I'm saving almost $1000 on the CPU!

For rendering, the 1950X usually trounce the 7900x, worth a triple check maybe?

You can maybe find benchmarks on the software editors websites (a lot do, to help customers getting the best possible hardware).

Worth a look!

Thanks for making me take a 2nd look at the TR. Have always been an Intel fanboy..but that article makes me rethink my purchase. Now to decide on a mobo! How do you like your H240X? I have the H240X2...just hoping I can get by with it for the TR as its just about the only AIO that fits properly in my Phanteks Enthoo Lux.

Have you looked at puget systems website?? They build custom systems for all kinds of applications. Plus have a wealth of research they do in house that they post results on they have done all the legwork already. Totally worth viewing their website for an extra check.
