Average Noise
The average noise output is high, considering its capacity. We should also consider though the platform’s not-so-high efficiency, which increases the thermal loads; hence, the cooling fan has to work more to remove the heat.
Fan Noise & Speed Maps @ 28-32 °C
[115V] There is no semi-passive operation, and the fan starts at high speeds, above 1000 RPM, so noise output is within 20-25 dBA from the start. At around 350W at 12V, the 30 dBA mark is passed, and with more than 405W, noise exceeds 35 dBA. Even in the worst-case scenario, noise is within the 35-40 dBA range.

Hi, please tell us how it is “almost” ATX 3.1? This is branded as ATX 3.0 lots of your other reviews also state ATX 3.1 when even the PSU box says ATX 3.1
Also does this PL550D have a 12V2X6 connector?
Please read the review, I explain everything in it.
Hello. Thank you for the information about this product. Did you measure the hold up time of this PSU under 100% load?
Yes
