Power for workstations and enthusiast PCs

The Decathlon DA1000-GH is a 1000W ATX power supply built for office workstations and high-end enthusiast PCs. It delivers a full-power single +12V rail backed by Japanese primary capacitors and maintains strict ±3% voltage regulation. Cybenetics Gold efficiency at 230V and Silver at 115V keeps waste heat low across typical mains voltages. A 140mm fan spins down to 18 dBA for quiet operation.

Replacing fixed-cable or lower-efficiency units

The semi-modular design lets builders keep only the cables they need, reducing clutter compared with fully fixed harnesses. Dual EPS 8-pin and eight PCIe 8/6-pin connectors cover multi-CPU boards and multi-GPU arrays without adapters. The jump is worth it when a build demands clean cable routing, 24/7 continuous output at 40 °C ambient, and certified efficiency that lowers running costs over time.

Steady output under sustained load

Rated for 24/7 continuous power at up to 40 °C, the unit holds its 1000W capacity without derating during long render or compute sessions. The single +12V rail avoids cross-load balancing issues when multiple high-draw devices pull simultaneously. Japanese primary capacitors and the 140mm fan maintain stable temperatures and low noise even after hours of full-load operation.

Questions about this item

What clearance does the 140mm fan need inside the case?

The 140mm fan draws air through the power supply housing; ensure the case vent or mounting area gives it unobstructed airflow so the 18 dBA minimum noise level can be maintained.

Which cables must stay attached during a semi-modular build?

The 24-pin ATX connector is fixed; connect the two EPS 8-pin and up to eight PCIe 8/6-pin cables only if your motherboard and graphics cards require them.

When should the 140mm fan be cleaned to protect 24/7 operation at 40°C?

Inspect the fan intake every few months; use compressed air to remove dust buildup so the single +12V rail continues delivering stable output at the rated temperature.
