Sonnet adds three PCIe slots to Thunderbolt 5 Macs
The Echo III T5 gives Macs three full-size PCIe slots through a Thunderbolt 5 connection.

The Module, Desktop, and Rackmount all carry the same three-card layout, with one x16 lane and two x8 lanes. The host port still sets the bandwidth ceiling, so the expansion is aimed at density rather than bandwidth.
The Module costs $1,099.99, while the Desktop and Rackmount are priced higher. The 400W supply and two Noctua fans are included, but the document does not measure power draw or sustained noise under load.
A studio can add audio, capture, storage, or networking cards without replacing the computer. A buyer seeking measured Thunderbolt 5 throughput, however, still lacks a tested path for a full-size card.
Lead with the slot count, keep the port caveat close, and leave bandwidth, power, and noise as open questions.
