My Ultimate Game Dev & Rendering Workstation — 4x RTX 5090s + Threadripper Pro

Hey everyone,

Here my battle station, after months of parts searching and putting it together…

Still waiting for coat hanger and library.

I just wrapped up what’s probably the most ambitious machine I’ve ever built — designed specifically for game development, 3D rendering, and other heavy production workloads. My goal was simple: pure power, stability, and efficiency.

After over 12 years, I really needed a upgrade. Timing was great, since we bought the parts couple months ago, so I was not impacted by the ram, ssd, gpu, cpu price hikes.

After a few months of planning, hunting down parts (and dealing with some serious case compatibility issues), it’s finally done — and running like a dream.

CPU

• AMD Threadripper Pro 9000 WX 9975WX

CPU Cooling

• HEATKILLER IV PRO for Threadripper, ACRYL NICKEL-BLACK

Motherboard

• ASUS Pro WS WRX90E-SAGE SE CEB Workstation Motherboard

Memory

• 128GB DDR5 (4x 32GB) 6800MT/s CL34 FURY Renegade Pro RDIMM Black XMP

Case

• Thermaltake w200 (We had to search for this case all over the place. It was very difficult to find a case that can support dual PSU)

Storage

• 4x Kingston FURY Renegade G5 2TB PCIe 5.0 M.2 NVMe SSD (SFYR2S)

Graphics Cards

• 4x MSI VCK GeForce RTX 5090 32G VANGUARD SOC LAUNCH EDITION, 32GB GDDR7, 512-bit

Case & Cooling

• Case: Thermaltake W200

• Radiator Fans: 11x Noctua NF-A20 PWM chromax.black.swap

• Case Fans: 26x LIAN LI UNI FAN SL INFINITY 140 RGB BLACK (UF-SLIN140-1B)

Water Cooling

• 2x CORSAIR iCUE Link XD6 RGB Elite LCD Pump/Reservoir Units (FlowDrive Max, 480×480 IPS LCD, temp sensor, 22 ARGB LEDs, 440 ml reservoir, Stealth Gray)

• 2x Alphacool NexXxoS XT45 Full Copper X-Flow 420mm Multi-Port Radiators

• MO-RA IV 600 Extreme Radiator (9x 200mm, Black, includes pumps, grills, legs, cables, reservoir)

• MO-RA IV 200 Extreme Radiator (2x 200mm, Black, includes pumps, grills, legs, cables, reservoir)

• 4x Alphacool Core GeForce RTX 5090 MSI Suprim v2.1 + Vanguard + GAMING TRIO OC Backplates

• 2x Bitspower In-Line Low-Restriction Filters

• 2x Aquacomputer High Flow NEXT G1/4 Flow Sensors

• Custom watercooling: Tubing, quick disconnects, coolant, 90° fittings, stop plugs, spacers

Power

• 2x MSI MEG Ai 1600T PCIE5 1600W, 80+ Titanium, fully modular ATX 12V PSUs

• ModMyMods 24-pin Dual Power Supply Adapter Cable, 30 cm, Black (MOD-0210)

Peripherals & Software

• Keyboard, mouse, mouse pad: Angry Miao Keyboard, Angry Miao Mouse

• OS: Ubuntu & Windows (Dual Boot)

Temps and Performance

Under full load (rendering + simulation stress tests), the highest temps I’ve seen:

• CPU: 28°C

• GPU: 29°C

Honestly, I didn’t think I could keep it this cool given the wattage, but the external rads and setup paid off massively.

Screens

• Samsung M9

• Wacom Cintiq Pro

A Few Notes

• The Thermaltake W200 was the hardest part to source, but it’s a monster and perfect for a dual-PSU, multi-GPU setup.

• I built this primarily for game development and rendering in Unreal Engine, Blender, and Houdini — and it’s been buttery smooth so far.

What do you think? Anything you would’ve done differently or added? I’d also love to hear how others are cooling multi-GPU setups.
