Corsair AI Workstation 300 for local AI
The Corsair AI Workstation 300 is a 4.4 L, 4 kg Ryzen AI MAX+ 395 desktop with 128 GB, sold with Windows 11 Home and a 1 TB drive on Corsair’s own US store, air-cooled by four fans, with a 300 W supply inside and a front button for its power modes.
2 years, with advance replacement
Tom’s Hardware calls Corsair’s cover a cut above: a replacement can ship before the faulty unit goes back, and support is based in the US.
Three power modes on a button
Quiet at about 55 W, Balanced at 85 W and Max at 120 W, switched from the front panel. Tom’s Hardware measured 39 dBA in Balanced and 43.4 dBA in Max.
AI Workstation 300 specs: what is inside?
The Corsair AI Workstation 300 is built on AMD’s Ryzen AI MAX+ 395, with 128 GB of Micron LPDDR5X-8000 at 256 GB/s and a 1 TB drive, in a black aluminum case of 249 x 188 x 98 mm and 4 kg, the heaviest of the five 395 boxes we compare.

Is the AI Workstation 300 liquid-cooled?
No. Corsair lists air cooling for the CPU and GPU, and Tom’s Hardware found two blower fans on a three-heatpipe fin stack, a slim fan over the SSDs and a fan in the 300 W Flex ATX supply. Early launch coverage that called it liquid-cooled with a 350 W supply was wrong.
The power-mode button
The Performance Level Selector on the front cycles Balanced (the default, about 85 W), Max (about 120 W) and Quiet (about 55 W), and the choice survives a reboot. Tom’s Hardware warns it has no light and gives no notice under Linux, so a bumped button can leave the box in Quiet mode without you knowing.
AI Workstation 300 noise
Tom’s Hardware measured 39 dBA in Balanced and 43.4 dBA in Max at 46 cm while generating images in ComfyUI, against 37.5 dBA for a DGX Spark in the same test. It is silent at idle and audible under light load.
Ports and storage
The front has an SD 4.0 reader, a USB4 port, two USB-A 3.2 Gen 2 ports and a headset jack; the back adds DisplayPort 1.4, HDMI 2.1, a second USB4 port, three more USB-A ports and 2.5 GbE. Storage is two M.2 2280 slots, reached by sliding the board and cooler out of the front. There is no PCIe slot, no OCuLink and no 10 GbE.
Which models fit in the AI Workstation 300 128 GB?
The AI Workstation 300’s 128 GB holds DeepSeek V4 Flash (101.5 GB) or Qwen3.8-Flash-Next (106.3 GB), and Corsair lets up to 96 GB of it work as graphics memory.

Why the 96 GB graphics share matters
DeepSeek V4 Flash, at 101.5 GB, is larger than the 96 GB graphics share Corsair lists. Plan to run it under Linux, where AMD’s ROCm guide shows how to give the GPU more of the 128 GB.
How fast is the Corsair AI Workstation 300 for local AI?
Corsair publishes about 50 tok/s for Qwen3.5-35B-A3B and 22 tok/s for Qwen3.5-122B-A10B on the AI Workstation 300. On the models we track, its Ryzen AI MAX+ 395 chip wrote DeepSeek V4 Flash at 41.9 tok/s with drafting in our lab and Qwen3.8-27B at 104.32 tok/s on LocalMaxxing, on other boxes with that chip. Every other run we have is in the full Strix Halo speed table.

These runs differ in engine, file or prompt. Drafting speeds some prompts far more than others.

AI Workstation 300 vs DGX Spark on speed
On DeepSeek V4 Flash with drafting, the 395 chip wrote 41.9 tok/s in our lab and one DGX Spark 35.3 tok/s in an independent run, each on its own setup. Tom’s Hardware tested both and found the Corsair hard to recommend for AI against GB10 boxes at its February 2026 price, with ROCm stability the main software risk.

Corsair AI Workstation 300 alternatives
Next to the AI Workstation 300, the DGX Spark is the box reviewers weigh it against, and the Lucebox Zero 495 puts a graphics card beside a Ryzen AI MAX+ chip. Every machine we compare is on the hub.
Model
Rank by
Our pick
Lucebox Zero 495, 128 GB
- Holds DeepSeek V4 Flash (101.5 GB) across the 32 GB card and 128 GB of unified memory.
- Writes it at 51.1 tok/s on our earlier 395 build, drafting on (our lab).
- $5,999, right at your budget.
Also consider
- Holds DeepSeek V4 Flash (101.5 GB) in 128 GB of unified memory.
- Writes it at 41.9 tok/s on another box with the same chip, drafting on (our lab).
- $4,600, $1,399 under your budget.
We make the Lucebox. It is ranked by the same rule as every other row; a run marked “on our earlier 395 build” comes from the previous Lucebox, with the same R9700 card.
- Lucebox Zero 495, 128 GB32 GB card + 128 GBCard + unified 63% used273 GB/s51.1 tok/s drafting on, our lab, on our earlier 395 build

The pick holds the model with room for the prompt, fits your budget and has the fastest run we can link to. Runs with drafting rank against each other first, then runs without it, then machines with no run, by memory speed. The amber band is the Lucebox's 32 GB card.
Corsair AI Workstation 300 review: who should buy one?
The Corsair AI Workstation 300 suits a buyer who wants a 395 box from a large brand today, in stock with Windows, 60-day returns and 2 years of advance-replacement cover, and who will pay more than smaller makers charge for that.
Buy one if
- You buy for an office that wants a known brand, US support and a box that arrives next week.
- You want to switch between quiet and full power from a button on the front.
- You want Corsair’s AI Software Suite, with Model HQ by LLMWare and ready-made agents, on Windows.
Look elsewhere if
- You need 10 GbE or a PCIe slot: it has 2.5 GbE and two M.2 slots only.
- You want the cheapest 128 GB 395 box: the GMKtec EVO-X2 was $3,500, against $4,599.99 here.
- You run Linux and may bump the mode button: nothing tells you it changed.
AI Workstation 300 vs Lucebox Zero 495: where each fits
Against the AI Workstation 300, the Lucebox Zero 495 is a $5,999 workstation that adds a 32 GB R9700 graphics card and comes with Ubuntu and its models installed, where the Corsair comes with Windows 11 Home and Corsair’s own AI apps.
We make the Lucebox Zero 495, so read this box as ours.
Where it fits
- Qwen3.8-27B on the R9700 card: 303.38 tok/s with drafting on a short code prompt (36.7 without) on LocalMaxxing, 2.9x the Corsair’s 395 chip on the same engine and file (2.6x without drafting).
- 192 GB if you need it: the Lucebox wrote DeepSeek V4.1 Flash at 33 tok/s with a 32K prompt, a model the Corsair’s 128 GB cannot hold.
- A second model running beside the first, one on the card and one in the unified memory.
Where it doesn't
- The Corsair is cheaper: $4,599.99 against $5,999 for 128 GB.
- You want Windows and a box in stock now.
- You want it small: 4.4 L against 11.97 L for the Lucebox.
