Average Noise
The PSU’s average noise output is below 26 dBA at 115V and slightly above 24 dBA at 230V. All in all, this is a quiet-operating PSU. Look at the vast differences with the “plain” A1000GL model.

There is no semi-passive mode, but this is entirely fine, as you can see in the respective graph, where the PSU’s fan operates at low speeds even at up to 550W loads, keeping its noise output extremely low. You will need Superman’s hearing to hear the fan spinning in its 400-600 RPM range. The 30 dBA mark is reached at approximately 730W at 12V, and with more than 760W, the noise level is within 35-40 dBA. At 795W and above, noise exceeds 40 dBA, depending on the load on the minor rails. All in all, this PSU is remarkably quiet at low and moderate loads, but it becomes notably louder at higher loads. The use of larger heatsinks on the secondary side could lower noise output at high loads, but it would also increase the production cost.

The 230V fan speed profile reduces noise output at higher loads, effectively lowering the average noise level.
I just saw this one in Amazon US for $375.
Hello Aris i had 160-170$ budget for my 1000W ATX 3.1, i’ve been researched on there are 5 options : MSI A1000GS, NZXT C1000 & Asrock PG-1000G, XPG Cybercore II, Montech Titan Gold, which is better options in terms of safety between all of them ?
All are good and safe units.
