- Certified Cybenetics Platinum efficiency across both 115V and 230V inputs, exceeding its nominal 80 PLUS Gold rating
- Full ATX 3.1 and PCIe 5.1 compliance with a dedicated 16-pin 12V-2x6 high-power cable
- Conformal protective PCB coating shields internal circuitry against dust, moisture, and debris
- Dual ball bearing fan and TUF 5K metallic capacitors backed by an 8-year warranty
- Lacks a 0dB zero-RPM mode, keeping the cooling fan spinning continuously at idle
Overview
Power delivery for modern high-draw computing rigs demands resilience as much as sheer wattage, and ASUS addresses this with an industrial, longevity-first design philosophy. Built to supply up to 1200W along a single dedicated 100A 12V rail, the supply handles demanding transient spikes and high sustained loads through compliance with the ATX 3.1 and PCIe 5.1 standards. The inclusion of a dedicated 16-pin 12V-2×6 power cable ensures standardized, direct connectivity for current-generation graphics cards, bypassing the clutter and potential contact resistance of multi-cable adapter bundles.
Internal architecture prioritizes durability under challenging operating conditions. The printed circuit board receives a protective conformal coating designed to resist dust, debris, and airborne moisture. Electrical stability is anchored by long-life TUF 5K black metallic capacitors alongside an active power factor correction circuit and an exhaustive suite of protections covering over-power, over-voltage, under-voltage, short-circuit, over-current, and over-temperature thresholds. With standard chassis dimensions measuring 5.91 x 5.91 x 3.39 in (150 x 150 x 86 mm), the fully modular enclosure integrates cleanly into mainstream mid-tower and full-tower computer cases.
Thermal management relies on a dual ball bearing fan engineered for sustained continuous service, contributing to an MTBF rating exceeding 120,000 hours at 40°C. ASUS opted against a zero-RPM idle profile, keeping the fan spinning constantly to ensure continuous airflow across internal magnetics and heat sinks. Despite constant rotation, acoustic tuning remains controlled, earning a Cybenetics Lambda A- certification alongside a Cybenetics Platinum efficiency rating across both 115V and 230V power lines.
