Overview

80 PLUS Platinum efficiency behind ATX 3.1 and a single 600 W connector — quiet, fully modular power on 105 °C Japanese capacitors, backed by a 10-year warranty.

  • Efficiency You Can Feel
  • ATX 3.1, One 600 W Connector
  • Quiet by Design
  • Individually Embossed Cables, Cable Combs Included
  • Built to Outlast the Build

Efficient. Quiet. Built to Last.

Platinum on both labs, one cable to the card, and a fan that stops.

A power supply earns its place by disappearing. The C1200 Platinum does it by wasting less power, by carrying the graphics card on one cable, and by not spinning at all until the load asks it to.

Efficiency You Can Feel

Certified 80 PLUS Platinum and Cybenetics Platinum. Less wasted power means a cooler, quieter build.

One Cable to the Card

ATX 3.1, with a single 12V-2x6 cable to the graphics card — no adapter in the path, no splice to get wrong.

A Fan That Stops

Zero RPM Mode, with a switch on the back panel

Under light load the fan does not turn at all, and a back-panel switch puts that call in your hands. When it does spin, a fluid dynamic bearing keeps it quiet.

Individually Embossed Cables, Cable Combs Included

Fully modular, embossed cables, combs included

Every cable is individually embossed with its comb already fitted, so the runs behind the tray stay flat without buying anything extra. Fully modular too, so only the cables the build uses go in the case.

Built to Outlast the Build

Japanese capacitors and six protection circuits

The parts that decide whether a supply lasts are the ones you never see. Japanese capacitors rated for sustained heat and a six-circuit protection suite covering voltage, current and heat, all behind a 10-year warranty.

Efficient at Rest

Modern Standby compatible

Modern Standby support means the supply holds its efficiency at a small fraction of rated load, so a machine that sleeps all day does not pay for it in wasted draw.

Only the Cables You Need

Nothing extra in the case

Fully modular, so only what the build uses goes in the case — one 12V-2x6, four 8-pin PCIe, both CPU cables and eight SATA connectors.
