Asus ROG STRIX 1000W Gold Aura Edition - Coil Whine RMA Issues

Level 7


I'm a long-time fan of Asus products due to their exceptional quality, which is why I've built an almost entirely Asus-based PC. However, my trust has recently been shaken. I purchased the ROG STRIX 1000W Gold Aura Edition 2-3 months ago, and last week, I was startled by a loud, boiling kettle-like sound - around 60db, according to the Decibel X: db Sound Level Meter app. I visited the Asus website and requested an RMA, but was told to contact the reseller, Overclockers UK, as they process the RMA.

The reseller diagnosed the issue as a "Coil Whine," but informed me that Asus does not consider this a valid reason for an RMA. Although I understand that Coil Whine is a common issue, it's concerning that it developed within just three months of use. I haven't even had a chance to play any intensive games (currently playing Prince of Persia: The Lost Crown). After researching the issue, I found a ROG forum post ( stating that Coil Whine typically occurs when the computer is under load. However, I'm experiencing this noise even when my system is idle, which means I'm subjected to it constantly.

I would have tolerated the noise if it only occurred under load, as mentioned in the forums. Unfortunately, the constant noise is unbearable. I contacted the reseller again, hoping to reason with them, but was told to reach out to Asus for a statement to determine if this issue could be classified as a fault. Asus insisted that I should pursue the RMA through the reseller, leaving me in a stalemate unless ASUS finally issues a statement to have this issue fixed.

I believe this issue should be considered a fault, as the PSU is not meeting its advertised Cybenetics Lambda A+ certification (under 20db). While the certification might refer to the fan noise, I'm confident that Cybenetics tests the entire PSU, not just the fan. I specifically chose this PSU for its silence, and this noise is a clear breach of the advertised sound level. If not considered a fault, this would be a case of false advertisement.

I've attached a video to this post. If you had this issue ASUS, would you consider tolerating this noise for the rest of your PC's lifetime?
