Power delivery for demanding builds

The Silverstone Technology DA1000-GH supplies up to 1000 W through a single +12 V rail. It targets systems that need strong, steady output for multi-GPU configurations or workstation workloads.

Semi-modular cabling and a 140 mm fan

Fixed cables cover the 24-pin ATX and one 8-pin EPS connector; the remaining EPS, PCIe, SATA and peripheral leads attach only when needed. The 140 mm fan spins down to 18 dBA at light load, and the unit is rated for continuous operation at 40 °C.

Cybenetics Gold at 230 V and Silver at 115 V

Efficiency sits between 87 % and 89 % under typical loads, with active PFC across a 90–264 V input range. The 160 mm depth fits most ATX cases, while Japanese primary capacitors and a full protection suite support the 100,000-hour MTBF claim.

Questions about this item

How do I verify the DA1000-GH is running correctly after installation?

The 140 mm fan should spin quietly and the system must power on without shutdowns; the unit delivers continuous 1000 W output at up to 40 °C ambient temperature with all protections active.

Which cables come attached and which must be added separately?

The 24-pin ATX and one 8-pin EPS (4+4) cables are fixed; the 12 SATA, 4 peripheral 4-pin and 8 PCIe 8-pin (6+2) cables are modular and included in the box.

Should I choose the 230 V Gold or 115 V Silver efficiency rating for my region?

The same unit carries both ratings; it achieves Cybenetics Gold at 230 V input and Silver at 115 V input, so no separate version selection is required.
