Hi everyone,

I’m planning a new high-end system for vMix and would like to get some feedback before I order everything.
My main goal is long-term stability, multiple PCIe capture cards, and solid 4K performance (a few 4K inputs and two 4K outputs).

Here’s the current hardware plan:

CPU: AMD Ryzen Threadripper 9960X

Mainboard: ASUS Pro WS TRX50-SAGE WIFI

GPU: Gigabyte AORUS GeForce RTX 5080 MASTER 16G

RAM: Kingston Fury Beast DDR5 – 64 GB (2×32 GB), 6000 MHz

CPU Cooler: Noctua NH-D9 TR5-SP6 4U (height limit in the case is 145 mm, so this was basically the only reasonable sTR5 air-cooler option)

Power Supply: be quiet! Straight Power 12 Platinum – 1000 W

Capture Cards (PCIe): Blackmagic DeckLink 8K Pro Mini & 2x Blackmagic DeckLink Quad 2

The board layout should give me enough space for the 5080 (3.5-slot) plus these three PCIe cards without blocking anything.


Before I lock this in:
Does this build make sense for vMix?
Anything you would change? CPU, GPU, cooling, PSU size, RAM amount — or anything else I should consider?

Thanks in advance for any input!

Thanks for the suggestions.
A few points don’t apply to my setup, so just to clarify:

• CPU cooler:
I’m using a 4U rack case with a 145 mm height limit. The NH-U14S TR5 doesn’t fit.
The NH-D9 TR5-SP6 4U is the correct cooler for this form factor.

• Capture cards:
I need many HD-SDI inputs, not multiple 4K streams.
Replacing the Quad 2 with 8K Pro G2 would cut my input count in half, so that won’t work for my workflow.
I already have 4K covered via the 8K Pro Mini.

• RAM
6000 MHz RAM is stable on TRX50 and more than enough for vMix.

Thanks again for your input!
