Sonnet Echo SE III T5 sells for $799.99 and fits 7.75-inch cards
Sonnet sells the Echo SE III T5 for $799.99, below the $1,199.99 Echo III T5 Desktop, and limits cards to 7.75 inches.
| Echo SE III T5 | Echo III T5 Desktop | |
|---|---|---|
| price | $799.99 | $1,199.99 |
| card length | 7.75 inches | 12.28 inches |
| aggregate bandwidth | 3,400 MB/s | 3,400 MB/s |
| slots | three PCIe 3.1 x8 slots | |
| dimensions | 6.5 inches wide, 11 inches deep, 4.6 inches tall | |
| weight | 3.7 pounds | |
| power | 6-pin auxiliary PCIe power connector | 400W power supply |
| fan | 17 dBA Noctua fan |
The smaller box keeps the same advertised 3,400 MB/s aggregate bandwidth as the larger model, so the trade is size, not speed.
It has three PCIe 3.1 x8 slots for full-height, half-length+ cards, and it connects to a Mac through one Thunderbolt 5 cable.
The 6.5-inch-wide, 3.7-pound enclosure targets Mac mini, Mac Studio, and MacBook Pro users who need space for capture, audio, networking, or storage cards.
The shared path means the slots do not each get 3,400 MB/s, and the article does not measure per-slot throughput, sustained fan noise, or which cards fit the 7.75-inch limit.
A Noctua fan is rated at 17 dBA, and a 6-pin connector supports cards that need extra power.
The larger Echo III T5 Desktop supports cards up to 12.28 inches and includes a 400W power supply.
Lead with price and card-length cut; keep the shared-bandwidth caveat, and do not claim per-slot speed.
