High-wattage ATX supply for extreme builds

The SilverStone DA1650 delivers 1650W of continuous power at 50? ambient temperature, making it suitable for ultra-high-end enthusiast PCs and multi CPU/GPU workstations. Its fully modular design uses a universal EPS and PCIe connector interface for flexible cable routing. The compact form factor helps it fit the majority of standard cases despite the high output rating.

1650W capacity with Gold efficiency headroom

Rated for 24/7 operation at full load, the unit maintains strict ±2% voltage regulation and low ripple and noise across the entire range. 80 PLUS Gold certification ensures high efficiency under typical workloads, reducing waste heat. All Japanese capacitors contribute to long-term stability. The platform runs out of headroom only when sustained draw exceeds the 1650W rating.

Semi-fanless 135mm FDB cooling with delayed shut-off

A 135mm fluid-dynamic-bearing fan stays off at low loads for silent operation, then spins up gradually as thermals rise. The delayed shut-off function continues airflow briefly after shutdown to dissipate residual heat. This design keeps noise minimal during normal desktop use while providing sufficient cooling for continuous 1650W output at 50? ambient conditions.

商品問答

Will the 1650 W output and EPS/PCIe connectors support the older dual-CPU workstation board I plan to keep?

The unit delivers 1650 W continuously at 50 °C with ±2 % regulation and includes universal EPS and PCIe cables, so it can power legacy multi-CPU or multi-GPU configurations that use those standard connectors.

How can I confirm the 80 PLUS Gold efficiency and semi-fanless mode are active after installation?

Monitor input versus output power with a watt-meter to verify Gold-level efficiency, and listen for the 135 mm FDB fan to stay off at low load and spin up only when temperature rises.

Which cables come in the box and what must I source separately for a full build?

The fully modular design supplies all required ATX, EPS and PCIe cables in the box; no additional power cables are needed unless your components require proprietary connectors not covered by the standard set.
