Green printed circuit board with an M.2 connector and four PCIe 1x slots

Graviton

Graviton TSR441 Riser Card M.2 to PCIe 4x 4x1x slot

SKU CH-M6AS-P85WQ

Converts an M.2 Key M slot into four PCIe 1x connections for mining risers

  • Expands one M.2 slot into four PCIe 1x connectors
  • Supports mining rigs needing multiple GPU risers from a single M.2 interface
  • Model TSR441 riser card with male-to-female PCIe multiplier layout
  • Provides four 1x slots for flexible GPU or adapter placement
  • New condition unit supplied in original packaging

Function and purpose

This adapter converts a single M.2 Key M slot into four PCIe x1 connectors. It is intended for mining rigs or test benches that need to attach multiple riser cards to one motherboard socket.

Interface limit

The host M.2 link provides only a PCIe x4 electrical connection, so the four downstream slots share that bandwidth. Each device will operate at x1 speed and total throughput cannot exceed the upstream x4 lane width.

Deciding specification

The board is identified as model TSR441 and accepts M.2 Key M modules only; Key B or Key E drives will not fit. Buyers needing a different key type or more than four x1 slots must choose another adapter.

Questions about this item

Should I choose the TSR441 riser card for a single M.2 slot or do I need a different model for multiple slots?

The TSR441 provides four PCIe x1 slots from one M.2 key M slot, so a single card handles multiple risers without extra models.

What bandwidth does the M.2 to PCIe 4x connection actually deliver to each x1 slot?

The M.2 key M interface runs at PCIe 4x total, which is split equally across the four x1 slots, giving each slot one lane of bandwidth.

Which PCIe generation does the riser card's x4 interface support, and does it limit the speed of attached devices?

The adapter uses a PCIe x4 electrical connection from the M.2 slot; the generation matches the host platform, so device speed caps at the host's PCIe version.
