ASUS ROG STRIX 1200W 80 PLUS Platinum Modular Power Supply

The ASUS ROG-STRIX-1200P-GAMING is a power supply that delivers 1200 watts through a single +12 volt rail, giving high-draw components the steady current they need. Builders who run top-tier graphics cards, multi-core processors, or heavy workstation loads will appreciate the headroom this unit provides for gaming, rendering, and content creation.

As a unit that meets the ATX 3.1 standard, it ships with a native 16-pin 12VHPWR connector ready for next-generation GPUs, four traditional 8-pin PCIe connectors, and dual 4+4-pin EPS plugs for power-hungry CPUs. All cables are fully modular, so you can install only what your build requires to improve airflow and keep the interior free of clutter.

Internal circuitry relies on GaN MOSFETs that reduce switching losses and allow a more efficient thermal layout. The result is an 80 PLUS Platinum rating with up to 92 percent efficiency at a 50 percent load. An IVS cable activates GPU-FIRST voltage stabilisation to minimise power droop during sudden spikes, helping maintain frame rates and system stability when a graphics card boosts to its highest clocks.

Cooling is handled by a 135 millimetre fan that rides on durable dual ball bearings. When system load stays below 40 percent, 0 dB mode stops the fan entirely, allowing silent operation during light gaming, office work, or media playback. Even under heavier loads, the fan curve is tuned for a noise level that remains below 25 dB.

A comprehensive set of protections guards every connected device against over-current, over-voltage, under-voltage, short circuits, over-power, and over-temperature events. This makes the unit a dependable choice for custom gaming rigs, enthusiast overclocking builds, or professional workstations that demand round-the-clock uptime.
