Mid Tower Power Build

[LED_Guy]

This is a major overhaul of my first build (from the days when an i7-5960X was a big deal)

= = = = = = Current target build = = = = = =

Revised December 7, 2020

 

CASE:              InWin S-Box Titanium*

MOBO:             Asus ROG Strix TRX40-E

CPU:                 AMD Threadripper 3970X

CPU cooling:   Cuplex Kryos NEXT sTRX4 FC, 360mm + 240mm radiators

GPU:                NVidia 3080

RAM:                G. Skill Trident Z 256GB DDR4 3600 MHz

Boot drive:      Samsung 980 Pro 512GB

Data drive:       Samsung 980 Pro 1TB

PSU:                 Seasonic Prime 1300 Platinum 

OS:                   Windows 10 Pro

 

 

I'm open to comments in general, except for the case.  It's a true one of a kind and I'm not about to give it up.

 

I am particularly open to suggestions for the cooling loop.  In my previous build I had a 360mm + 240mm radiator.  That’s a lot to pack into a mid tower.  I want a nice clean interior, so I may dispense with the 240mm for the rebuild.  With 32 cores, I'm not too concerned about major overclocking!

 

This is a work + play computer.  I need the cores for optical design (ray trace) and Monte Carlo simulations.  I will be starting with 64GB (recycled from the previous build).  Ray trace design is very memory intensive and even 128GB isn't really enough for some simulations.  I would welcome suggestions for good quality ECC RAM.  I will be upgrading up to 256GB in the future.

 

I'm looking for recommendations on the PSU.  (Platinum+). With a single 3090 1000W should be sufficient, but if I go SLI then I will probably need 1200-1300W.

I suggest having a couple of RTX 3090 instead, a single one can out perform a RTX6000 by 50+%.

SolidWorks (CAD) and Flow (CFD) won't play with an RTX 3090.  It's Quadro or run everything through the CPU.

 

I read the quad RTX 3090 article earlier this evening.  I was shocked at how well everything scaled, but alas that will have to wait for a recreational build.

I talked to SolidWorks Technical support.  Flow Simulation isn't coded for GPU acceleration.  The only benefit I would get with a Quadro is that I could rotate a rendered image faster.  Absent a Quadro, the rotation uses one thread and the rendering is picked up by additional threads.

 

Since I don't really have a reason to make videos of rendered parts being rotated and since Flow will benefit from the additional cores in a 3970X, my money would be better spent hunting down a 3090 (or two) or worst case a pair of 3080 cards . . .

Getting close to being operational.  I am waiting for my PSU to arrive.

 

The packaging for my CPU is rather impressive, then again for a $2k CPU AMD can afford to do it right.
