This is the first time I've posted my build here, don't judge me harshly!
My latest workstation project is for working in SolidCAM and Solidworks.
4 and 5 axis milling calculations require a lot of memory and single-threaded/multi-threaded performance.

My build specification:
CPU
- Ryzen 9 9950x (Curva -30, TJmax 85c), 160W, The maximum temperature under load is 81 degrees, with stock performance.
CPU_COOLER - Noctua NH-L12S-X77, with replacement of the native 15mm fan, with a 25mm NF-F12 Industrialppc-3000 PWM fan
--
In order for such a large cooler to fit, I had to make a frame-expander-spacer for the case on a CNC milling machine!. If someone needs a 3D model or a custom-made frame, I can produce it at a separate price, for more information, see my personal messages.
the frame was made of aluminum AMG6, in solidworks + SolidCAM
--
GPU
- Rtx 3050, GIGABYTE Low Profile GV-N3050OC-6G, a computer for work, at most I play supreme commander, so a cold 75w graphics card without additional power is my choice. The native casing was removed and 2 80mm Arctic P8 max fans were installed.
MB - ASRock B650I Lightning WiFi, it works perfectly, without complaints
RAM - 64GB DDR5, (33.8mm) ADATA XPG Lancer Blade [AX5U6000C3032G-DTLABBK], it works perfectly, without complaints.
SSD - 1TB Samsung 9100 PRO [MZ-VAP1T0BW] it works very perfectly, without complaints.
PSU - ACD FL0600 600W FlexATX OEM with PWM, max temperature 40-50C. absolutely silent!
Case fan - 4x Arctic P8 Max 80mm, the fan mounting frame next to the processor power connector had to be cut off with a drill, for more information, see the photo, the fans were attached using 3m tape.
Now I am waiting for the delivery of mini antennas "5,8G Lollipop 4 RP SMA" from the FPV drone to put them in this computer.

It was important for me to assemble a powerful portable (For daily wear) workstation, with the most productive system, noise does not matter to me. Compared to my work laptop, which has a Ryzen 7 8745Hs processor and 32Gb DDR5, this computer calculates a gear project in solidcam by as much as 3X times faster!

WOW!!!!!!!!!!!!!!!!

I will be building this as well. Our requirements are exactly the same. Have been literally researching something like this for ages.

How is the noise on the 25mm fan?

Just a heads up, there are reports that this asrock board is killing the 9000 series cpus:

During peak load, it makes noticeable noise. But this is the price to pay for 160W of performance in 5L, if you limit it to 75C in the bios, it becomes much quieter, and we lose 5% of performance.
A 25mm fan is MUCH better than a 15mm fan under stress!

Do you think a 70w GPU and the 9950x could be run on a 300w power supply? I'm thinking of using this case: https://caseend.com/data/bug/bug-d1 and an external power brick (lower heat, noise, etc).
I think 300W won't be enough for a 160W processor and a 70W graphics card. Considering that, as a rule, these are not real 300W. I would recommend taking something more reliable for such an expensive piece of hardware.

Thank you, I'll look into this issue, because my computer just crashed in the browser once, but I was doing Curva -40 at that moment, so maybe it was related to a lot of undervolting.

ok I have studied the problem thoroughly! Asroc released 3 bios updates to fix this, in the last one (3.4) they even fixed the socket voltage at 1.2v, and level3, although it used to be auto (alternating voltage), although all other manufacturers had static 1.2v for a long time. I conducted a number of tests and stress tests for voltage monitoring, EDC, PPT, and SocV, everything is stable, EDC max 125A, PPT max 162W, SocV stable 1.2 (1.812v on another sensor). The TjMax 75C consistently limits power when this temperature is reached. If I set the TjMax 85C, then there is no limit, because my processor can't even heat up to 82C))), noctua are just the gods of cooling, they were able to cool the 9950x with some kind of 77mm cooler

I strongly advise you to assemble the assembly as I have, with the FL0600 600w server power supply, it absolutely does not heat up, does not make noise, and is more reliable than any external power source.

That could definitely work, but which internal power supply would you be pairing the brick with?

For instance, Pico Box has the X3-ATX-300 but it wouldn't really be sufficient, as the 12V rail is only rated for 18A (meaning you're practically limited to 216w total)

I am using a 330w DC-ATX module by G-Unique, which can do 27A on the 12V rail (i.e. the full 330 watts)
Here is a link to this product: https://www.goofish.com/item?id=876723786809
The website is intended for Chinese users - you can use a third-party site like Superbuy to order on your behalf.
Also, you will need to communicate that you want the 330w version with graphics plug, as the default version is lesser.

I understand ordering through a proxy can be somewhat daunting.
As mentioned, I am currently using my 330w module, but if you are particularly interested in it, I could make a post in the trade forum.
From your profile, I think we might even be in the same country!

Another option would be to go with a case that can fit Meanwell's LOP-300-12 power supply.
This still requires a DC-ATX module, but since the Meanwell outputs 12V, the module can be simpler in design.

After reading a lot of things, I still replaced the motherboard with an ASUS B850-I. I had to work hard to find drivers for Bluetooth and wifi for windows 10!, they were everywhere only for windows 11. The B850-I allowed me to heat my ryzen 9 up to 200W! On the asrock b650-i motherboard, I had a maximum of 16,300pt in cpuZ, the asus b850-I allowed me to get 18,500pt on the same processor!, the asus bios is much nicer, the socket voltage was 1.25, I set 1.22 just in case))). The memory on the expo started up immediately, at 6000 mhz, I blindly set the CURVA -30 ALL CORES, and everything worked perfectly!. TJMAX has set 85C. at 200W, the processor is already reaching the 85C limit pretty quickly, but at 84 it is almost no higher!. So NH-L12S_X77 +25 MM FAN 3000 industrial, just the top of what you can put in 77mm!!!, 200W carl!
