be quiet! Pure Power 13 M 1000W ATX 3.1 PSU vs OWC Envoy Express Thunderbolt NVMe Enclosure

Both have 0 GB memory, so bandwidth decides. OWC Envoy Express Thunderbolt NVMe Enclosure's 0 GB/s vs 0 GB/s translates directly to more tokens per second at equivalent model sizes.

Neither is optimised for image generation, but OWC Envoy Express Thunderbolt NVMe Enclosure's 0 GB/s bandwidth makes generation faster. Both run SDXL via Metal (macOS) or ROCm (Linux). Expect slower generation times than a discrete GPU.

OWC Envoy Express Thunderbolt NVMe Enclosure draws 999W at peak vs 1000W — a 1W difference. Running AI workloads 12 hours/day, that's roughly 4 kWh saved per year. For always-on inference, OWC Envoy Express Thunderbolt NVMe Enclosure has meaningfully lower operating costs.

OWC Envoy Express Thunderbolt NVMe Enclosure edges ahead overall — better memory, bandwidth, and user ratings for local AI workloads. The gap is real but not always worth the price difference; assess based on your primary use case.

Q1Which runs Ollama faster — be quiet! Pure Power 13 M 1000W ATX 3.1 PSU or OWC Envoy Express Thunderbolt NVMe Enclosure?

be quiet! Pure Power 13 M 1000W ATX 3.1 PSU runs Ollama faster. Its 0 GB/s memory bandwidth vs 0 GB/s means faster token generation — roughly — more tokens/second on the same model. On Llama 3.1 8B, expect around 0 tok/s vs 0 tok/s.

Q2Can either mini PC run Llama 3 70B?

Neither mini PC has enough memory for Llama 3 70B without heavy CPU offloading (39 GB required at Q4_K_M). You would need a Mac Mini M4 Pro with 64 GB unified memory or a discrete GPU with 24 GB VRAM paired with ample system RAM.

Q3Which is better value for local AI in 2026?

be quiet! Pure Power 13 M 1000W ATX 3.1 PSU offers better performance-per-dollar for AI workloads due to its 0 GB/s bandwidth advantage. However, if price is the primary concern and 7B–13B inference is the goal, both get the job done — the gap matters more at higher workloads and model sizes.

Q4Which has better software support for local AI?

Both run Ollama well. AMD-based mini PCs offer ROCm acceleration on Linux; Intel-based ones are adding OpenVINO support. macOS Apple Silicon has the most polished Ollama experience.
