What this power supply delivers

The Pure Power 12 is a 1000 W ATX 3.1 unit with 80 PLUS Gold certification and up to 92.9% efficiency. It uses a single 12 V rail and a 120 mm fan for quiet operation. The non-modular design includes a 300 W PCIe 5.1 12VHPWR connector plus two 6+2 pin PCIe cables for high-end graphics cards.

What to verify before ordering

Confirm your case fits a standard ATX 12V power supply and that your motherboard accepts the 24-pin and CPU power cables built into the unit. Because the cables are fixed, ensure you have routing space for all leads, including the native 12VHPWR and the two 6+2 pin connectors. Check that your GPU power requirement matches the 300 W PCIe 5.1 or 6+2 pin options provided.

Behaviour under sustained load

The Gold-rated platform maintains efficiency above 90% across typical loads, reducing waste heat during long sessions. LLC topology keeps the 12 V rail stable when the system draws continuous power. The 120 mm fan speed scales with temperature, so noise stays low even when the supply runs near its 1000 W rating for extended periods.

Questions about this item

What cables are included with the Pure Power 12 1000W and what must be purchased separately?

The box contains one 300W PCIe 5.1 12VHPWR connector and two PCIe 6+2 pin connectors attached to the non-modular unit; no extra cables are needed for those connections.

Should I choose the 1000W model or a lower wattage for an ATX 3.1 build?

Select the 1000W version when your GPU and CPU combined demand approaches that ceiling; it delivers a single 12V rail and full ATX 3.1 compliance for high-end configurations.

What does the 92.9% efficiency figure mean once the PSU is installed in my PC?

At typical loads the unit converts up to 92.9% of AC input to DC output, reducing waste heat and fan noise while meeting 80 PLUS Gold requirements.
