1200W Gold PSU for High-End Builds

This ASRock unit delivers 1200 W of continuous power with 80 PLUS GOLD certification. It is fully modular so only the cables you need stay inside the case. Japanese capacitors and Cybenetics PLATINUM and LAMBDA A ratings back long-term reliability. The white finish suits light-themed systems.

ATX3.1 and PCIe5.1 Interface Limits

The power supply meets ATX3.1 and PCIe5.1 specifications for modern graphics cards and motherboards. A native 12V-2x6 connector is included in a dual-colour design. The 135 mm FDB fan runs under iCool intelligent control for quieter operation at lower loads. Cable routing stays clean because every lead is detachable.

Compatibility Checks Before Ordering

Verify that your chassis can accommodate a fully modular ATX power supply of this class. Ensure the motherboard and graphics card require the 12V-2x6 connector or standard PCIe plugs provided. Confirm the total system draw stays within the 1200 W rating. Check that the white colour matches your build aesthetic.

Questions about this item

Should I pick this 1200 W unit or a lower-capacity model?

Choose 1200 W when your build includes multiple high-end GPUs or heavy overclocking; a smaller unit is sufficient for single-GPU systems with modest power draw.

What does the 80 PLUS GOLD rating mean for daily use?

It guarantees at least 80 % efficiency at typical loads, so less electricity is wasted as heat and your power bill stays lower.

How do the ATX 3.1 and PCIe 5.1 labels affect cable compatibility?

They confirm the PSU includes a native 12V-2x6 connector that can deliver the full 1200 W to modern graphics cards without adapters.
