Power delivery for PCIe 5.1 GPUs

This 1000 W ATX power supply carries 80 Plus Gold certification with up to 90 percent efficiency. It ships with two native 12V-2x6 connectors, each rated to supply up to 600 W to a PCIe 5.1 graphics card. The unit is fully modular and uses embossed jacket cables with premium copper alloy connectors.

Who this suits and who it does not

Builders installing a single high-end GPU that requires the 12V-2x6 interface will find the dual connectors convenient. Systems that demand more than 1000 W of total output or need more than eight SATA power connectors should look at a higher-capacity or differently configured unit.

The deciding specification

The dual native 12V-2x6 connectors are the feature that determines fit. If your graphics card uses this interface, the power supply can deliver up to 600 W per port without adapters; if it does not, those connectors will go unused.

Questions about this item

Should I pick the 1000 W model or is a lower-wattage unit enough?

Choose 1000 W if your build includes a PCIe 5.1 GPU that can draw up to 600 W per 12V-2x6 connector; a lower-wattage PSU would not guarantee that headroom.

What does the 1000 W rating mean once the PSU is installed in my PC?

It means the unit can sustain 1000 W total output across its two +12 V rails while maintaining up to 90 % efficiency at typical loads, so your components receive stable power even under heavy gaming or rendering.

How does the ATX 3.1 and PCIe 5.1 readiness affect what I can plug in?

The two native 12V-2x6 connectors each deliver up to 600 W, letting you power a PCIe 5.1 graphics card such as a 5090 or 5080 without adapters, while the ATX 3.1 compliance ensures proper transient response for modern GPUs.
