1000W 80+ Gold ATX Power Supply

This 1000W ATX12V unit delivers 80 PLUS GOLD efficiency with a single +12V rail rated at 83A. The 140 mm depth fits standard ATX cases, and full modular cabling lets you install only the connectors required. A 120 mm fluid dynamic bearing fan runs under hybrid control for quiet operation.

Ideal for High-End Gaming and Workstation Builds

The six 6+2-pin PCIe connectors and ten SATA power plugs support multi-GPU configurations and dense storage arrays. Builders who need a compact footprint and cable flexibility will benefit. Systems limited to shorter PSU bays or lower-wattage requirements should verify clearance and power needs first.

Check Case Depth and Connector Requirements

Confirm the chassis accommodates a 140 mm deep power supply and that the motherboard uses a standard 20+4-pin main connector. Ensure the GPU power demand matches the available 6+2-pin leads and that the 100-240 V input range suits the local mains supply.
