1000W ATX3.1 PSU for modern builds

The ASRock SL-1000G is a 1000W fully modular power supply built to the ATX3.1 and PCIe5.1 specifications. It carries 80 PLUS Gold and Cybenetics Platinum efficiency ratings plus a Cybenetics Lambda A noise certification. A native 12V-2x6 connector supports current-generation graphics cards without adapters.

Sustained load behaviour with iCool control

Two fan modes alter long-term acoustics and thermals. In iCool Mode ON the 135mm striped axial FDB fan remains off during low to medium loads, cutting noise and raising efficiency. In iCool Mode OFF the fan spins continuously for consistent cooling under heavy, prolonged workloads. Both modes draw on 100% Japanese capacitors for stability.

Check compatibility before ordering

Verify that your case accepts a standard ATX form factor unit and that your motherboard and graphics card use the 12V-2x6 power interface. Ensure cable routing space suits a fully modular design where every lead is detachable. Confirm the 1000W maximum output matches the total draw of your planned components.

Questions about this item

Will the native 12V-2x6 connector work with my PCIe 5.1 graphics card without an adapter?

Yes, the unit includes a native 12V-2x6 cable that plugs directly into PCIe 5.1 graphics cards, so no adapter is required.

Can I run the fan completely silent at low loads?

In iCool mode the 135 mm fan stays off until load or temperature rises, giving silent operation during light use.

What efficiency rating does this 1000 W unit carry?

It holds 80 PLUS Gold and Cybenetics Platinum certifications, meaning at least 80 % efficiency at typical loads and Platinum-level performance across the curve.
