    Choosing the right power supply affects the lifespan and reliability of your computer. ADATA’s HM Series should be at the top of your list. Certified by 80 Plus Bronze to achieve 82% sustained power, the HM Series provides continuous power in a full range of wattages and includes high-quality 100% Japanese made capacitors. Better yet, the HM Series equips modularized cable management and an intelligent dual ball bearing tri-color LED fan that reduces resonance of the fan axis, resulting in high airflow cooling, and also keeps you informed of your computer’s power status. ADATA HM Series power supplies are the one that delivers you high-efficient performance and ultimate reliability in the market.

    Stable Power, Always Keeps You Noted
    ADATA HM Series power supplies are designed especially for the gaming enthusiast, PC enthusiast and overclocker, allowing for uncompromised productivity and efficiency. Available in a multitude of wattages (550, 650, 750, 850 and 1,200 watts), ADATA HM Series power supplies deliver superior performance, reliability and protection for all types and levels of applications. In particular, the HM Series equips an intelligent dual ball bearing LED fan with a tri-color output power display for easy access to power consumption stats (green for low load; blue for normal load; red for full load)1. The HM Series high-quality Japanese capacitors provide voltage regulation, filtering, buffering function and a long-lasting stable power output; the mean time between failures (MTBF) is proven at a minimum of 100,000 hours. All of this is topped with a 3-year limited warranty.

    State of the Art and Neat Design

    ADATA HM Series power supplies feature a smart modularized cable management that allows you to adjust cables according to the number of devices flexibly, reduces unused cable clutter and improves internal airflow for high-efficient heat dissipation within the case. To achieve ultimate gaming performance, the 850W HM Series power supply is NVIDIA® SLI®-ready certified. In addition, it is compliant with ATX 12V v2.2 and v2.3 and EPS 12V v2.92 to support various system configurations and chassis.

    What is 80 Plus?
    80 PLUS is an initiative advocated by Ecos and EPRI to promote energy efficiency in computer power supplies. This certification endorses products that exceed 80% energy efficiency at 20%, 50% and 100% of their rated load, significantly reducing energy and extending the lifespan of power supplies.

    1. The load status display of the intelligent tri-color (Green, Blue, Red) LED fan is resulted from testing in the normal temperature of 25 °C. The actual load display may vary by the room temperature where in use.
