Planning build with 4 GPU's for 3D rendering

[DEDAAN]

Budget (including currency): Around 10K euro

Country: Netherlands

Games, programs or workloads that it will be used for: 3D Rendering (GPU)

Other details:

 

• Intel Xeon W-2245
• Asus WS C422 SAGE
• Arctic Liquid Freezer II
• 64GB (4x16) Kingston ValueRam DDR4 3200MHz
• 4x 3080 ti
• Samsung 970 Evo 500 GB
• 2x Corsair HX Platinum 1200 W 80+ Platinum
• Open Air Mining Frame
• 4x 300mm PCIe Riser

Hi All,

 

I'm currently planning a new build at work. We are planning to build a total of 4 of these as a farm, these will be used for 3D Rendering.

Below are the current specs I have in mind, the issues I seem to be running into is the PSU.

 

The plan is to use mining rig cases so we can hook-up as many GPU's as possible to single pc.

Cost efficiency is way higher this way.

 

At first I was thinking of using 2 1200W psu's, because 2000W psu's are 1. more expensive than 2 psu's and 2. nowhere to be found (Availability).

Is there something Im forgetting, any way to make 2 PSU's work safely?

 

Anything else I'm forgetting?

Feedback is appreciated!

Where do you get the gpus from and which ones ?

Why intel tho?

Amd epyc is cheaper and offers more cores

 

Consider getting an ice lake or whatever those 10nm xeons were called so if you cant use epyc youll atleast have decent power efficiency

Not any particular model, we chose to use a open air case so we're not stuck with 2 slot designs.
Multiple stores have gpu's in stock here, for marked up prices of course.

The main reason we use the xeon series is because we need the pcie lanes.
Since we will be rendering with gpu programs, the amount of cores etc doesn't help us.

All the cpu does is load the scene, for that less core with high clocks is usually better than more cores with lower clocks.

As for this particular model, I looked at what our desktops are already using, and copied from there.

Epyc has alot of pcie lanes aswell and if you get their lower core count cpus like 16 core, those have quite high clockspeeds

 

Though if you do go xeon go for the 10nm ones

I was at first thinking of using amd cpu's aswell, but every other system we have here runs on Intel, so just to be safe I will be going with Intel for this system too.

I will definitly look into the 10nm cpu's, thanks for the tip!
