  • 1600 W rated output powers six graphics cards

  • Active PFC corrects power factor across 140–265 V input
  • Eight-pin plus dual six-pin connectors feed GPU power directly
  • Six SATA ports supply drives and risers

Purpose-built mining PSU

The Graviton TF1600W-B-ATX is a 1600 W server power supply designed to run six graphics cards such as RX470, RX480, RX570 or RX580 in a mining rig. It delivers 1600 W rated power from an AC 140-264 V input and uses active PFC. The unit is non-modular and carries a 90 PLUS GOLD efficiency grade.

Fits high-density GPU rigs, not general builds

This supply suits miners who need eight 12 V pins (8 pin + 2 x 6 pin) plus six SATA ports and four D-type connectors for dense GPU deployments. Builders requiring modular cables, redundant server frames or quiet office operation should look elsewhere because the fixed harness and high-output fan target continuous mining loads.

1600 W rating with 90 PLUS GOLD efficiency

The single specification that decides fit is the 1600 W continuous rating backed by 90 PLUS GOLD certification, which confirms the unit can sustain the 1300 W typical draw of a six-card rig without derating.

Questions about this item

What are the physical dimensions of the TF1600W-B-ATX unit?

The power supply measures 160 mm in length, 150 mm in width, and 85 mm in height.

How is the non-modular cable loom connected, and which step is often missed?

All cables are fixed; the 20+4 pin motherboard, 8-pin CPU, eight 6+2 pin GPU, six SATA, and four D-type connectors must all be routed before securing the unit with screws.

When should the internal fan be cleaned or replaced on this 1600 W server PSU?

The Taiwan double-ball-bearing fan should be cleared of dust every few months; replace it if bearing noise appears or airflow drops under sustained loads near 1300 W.
