1000W ATX 3.0 power supply for high-end builds

The TOPOWER TOP-1000WG1 delivers 1000 W through a single +12 V rail and meets ATX 3.0 and PCIe 5.0 requirements. It includes a native 12VHPWR cable for 4080 and 4090 class graphics cards. Full modular cabling keeps the build clean and airflow unobstructed.

Check ATX 3.0 support and 12VHPWR routing

Verify that your motherboard and GPU accept the 12VHPWR connector and that the case can accommodate a 160 mm deep unit. The 24 pin main connector and six 6+2 pin PCIe plugs cover most modern layouts, but confirm cable reach for your specific component placement before ordering.

140 mm fan with silent switch and Gold efficiency

A 140 mm fan runs at lower RPM under typical loads, and a silent switch lets you prioritise quiet operation. 80 PLUS Gold certification means high efficiency across the 100 to 240 V input range, reducing waste heat and lowering overall power draw during normal use.

Questions about this item

What cables come in the box and which ones must I buy separately?

The fully modular unit ships with a 24‑pin ATX cable, a 12VHPWR connector for PCIe 5.0 graphics cards, six 6+2‑pin PCIe cables and twelve SATA power leads; no extra cables are required for a standard build.

How do I decide between the available versions or capacities of this model?

This specific SKU is a single 1000 W ATX 3.0 unit; there are no alternate wattages or versions listed, so the only choice is whether 1000 W matches your system’s peak draw.

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

It guarantees up to 1000 W of continuous DC output on a single +12 V rail, with 80 PLUS Gold efficiency and a 140 mm fan that can run quietly under load.
