1200 W ATX 3.1 power supply for high-end builds

The Montech Century II 1200 delivers 1200 W of continuous power through an ATX 3.1 compliant design. It targets enthusiasts building systems with modern graphics cards and multi-drive arrays. Full modular cabling keeps the interior tidy and airflow unimpeded.

Sustained load behaviour

Dual efficiency certifications confirm low waste heat during extended gaming or rendering sessions. The 135 mm fluid-dynamic-bearing fan spins up only when needed, thanks to a zero RPM mode at light loads. Japanese capacitors on every rail maintain stable voltages under prolonged 100 A draw on the 12 V line.

Compatibility checks before ordering

Verify that your case accepts a unit up to 150 mm deep and provides clearance for the 135 mm fan exhaust. Ensure the motherboard has a 20+4 pin main socket and that your graphics cards can use the supplied 12V-2x6 or six 6+2 pin PCIe cables. Count SATA devices against the twelve available connectors.

Perguntas sobre este artigo

How loud does the 135 mm fan get when the 1200 W unit runs all day?

The 135 mm FDB fan includes a zero RPM mode that stops the blades at low loads, keeping noise near silent during typical use.

Which cables must I already have to connect the 6 x 6+2-Pin PCIe and 12 SATA connectors?

The supply is fully modular, so every PCIe and SATA cable ships in the box; no extra cables are required.

Will the ATX 3.1 design and 150 mm length fit my older case and motherboard?

The 150 mm depth matches standard ATX bays, and the 20+4 pin main connector works with legacy boards while the 12V-2x6 cable supports newer GPUs.
