1200W ATX 3.0 Power Supply

The ASUS ROG Strix 1200W Gold Aura Edition is a fully modular ATX 3.0 power supply rated for 1200W maximum output. It carries 80 PLUS Gold and Cybenetics Lambda A+ certifications for efficiency and low noise. The unit includes a native 16-pin PCIe Gen 5.0 cable alongside four 8-pin PCIe connectors. An aluminium case and large ROG heatsinks couple to the internal transformer to reduce temperatures.

Upgrade from lower-wattage or non-ATX 3.0 units

This supply replaces older units that lack the 16-pin PCIe 5.0 connector or cannot deliver 600W through a single cable to modern graphics cards. The jump is worth it when a build demands 1200W of continuous power with tight voltage regulation and certified quiet operation under load. Builders staying with 8-pin GPU power or systems drawing well under 800W will not use the headroom or the Gen 5 cable.

Check case length and cable routing before ordering

Verify the chassis accepts a 180mm deep PSU and that the 600mm motherboard, 650mm CPU and 675mm PCIe cables reach their headers without strain. The package includes two CPU 4+4-pin cables, one 16-pin to dual 8-pin adapter and SATA cables with 400mm first connectors. Ensure the single 16-pin PCIe 5.0 cable matches the graphics card requirement; cards needing two native 16-pin connectors cannot be powered from this unit.

Questions about this item

Will this PSU fit in a case that only allows power supplies up to 180 mm deep?

The unit is exactly 180 mm long, so it fits the maximum depth but leaves no extra clearance for cables behind it.

Can I power a graphics card that requires the new 16-pin PCIe Gen 5 connector?

Yes, the box includes a dedicated 16-pin cable rated for up to 600 W and the PSU meets ATX 3.0 guidelines for that connector.

How many SATA drives can I connect using the supplied cables?

You receive one 1-to-2 SATA cable and one 1-to-3 SATA cable, giving five SATA power plugs in total.
