80 Plus Bronze Certification

Brains and Bronze

The high-quality components used in ASUS Prime power supplies ensure efficient and reliable operation worthy of an 80 PLUS Bronze Certification. The efficiency also leads to low temperatures within the PSU, facilitating an even quieter acoustic profile.

Dual Ball Fan Bearings 2X Longer Lifespan

Dual ball bearings boast an extensive lifespan of up to 80,000 hours, lasting twice as long as sleeve bearings and exceeding even fluid dynamic bearings. This means long-lasting, reliable cooling with minimal noise when you choose the ASUS Prime Bronze series.

135mm Fan Design

The 135mm fan can reduce heat more effectively, making the PSU cooler and less noise
