Threadripper & Ryzen only builds (3rd Gen starts on page 50)
Vuk:
If you want to run the 3990x with PBO a 1000w PSU is the bare minimum. Just for reference I tested my 3990x WS (cooled with a custom loop) with PBO turned on and it was pulling out around 880-920 watts out of the wall during rendering in Corona. The other 3990x is currently being used as a rendering node, clocked @ 3.7ghz all core and is pulling around 550 watts (cooled with the ice giant).
850w is ok if you are running on stock since on stock is pulling out around 370-390 watts when rendering. My guess is that it would pull out even more when gaming or in any task where you would use both your cpu and gpu at the same time.

Thanks for your feedback @Vuk,
I've read a review of the FSP Hydro PTM Pro 1200W, although it's a good PSU, it looks like Corsair is doing a better job: so just to be on the safe side, I've chosen the 1600W Corsair AX1600i Digital 80+ Titanium - Modular instead.
Given my GPU is a MSI RTX 3060 Ventus 2X OC - 12GB, the whole machine will have enough power, even when PBO is on.

Hello! Three questions for the tech people here...
1. I may get a new 3990x system built by Puget Systems near Seattle, USA. Anyone purchase from them, and if so, good experience?
2. RAM: Certainly will get 128gb, but for the sake of future-proofing-- is 256gb overkill?
3. RTX 3090. Aside from Corona, wanting to dabble in real-time more with UE and other applications. Again, is this overkill? Curious if anyone is like me in this forum and starting to play in that space, and if so- does a cheaper card get the job done just fine?
Thanks for the help!

Hi @shoebu23,
1/ I can't answer point 1 unfortunately as I never bought anything from them.
2/ About the RAM, I recently bought a new 128GB RAM workstation dedicated to Archiviz with Corona: I think 128GB is enough unless you really don't optimize your scenes and/or you work on unbelievably complex scenes with many many objects, huge textures etc ... I would say for ArchViz 64GB is the minimum nowadays, and 128GB is absolutely fine. I don't really see the point to go for more than that, unless you're working with simulation software like Houdini or similar, but I'm not an expert.
3/ About the GPU I don't work with UE so I can't give you any relevant advice here.
The only thing I can say is if you work on regular scenes with Corona, I mean again you're not working on totally un-optimized scenes (eg you make use of proxies to keep a decent overall amount of polygons in your scenes so that you don't need a monster GPU to move in your viewports) you should be fine even with a lower-end GPU. I bought a MSI RTX 3060 OC 12GB and I guess I will be fine for regular ArchViz work. I didn't receive my machine yet so I can't be sure yet of what I'm saying here, but it should be enough for my needs AFAIK.
Hope it helps.

Hi guys,
A quick question: I have to choose one of these 2 CPU coolers:
_ Cooler Master ML360 Mirror TR4
_ Noctua NH-U14S TR4-SP3
The store's advice is to go for the Cooler Master as they say the Noctua may not be enough to cool my 3990X even in a push-pull configuration.
Which one would you choose?
