Verified purchase - review from a price comparison website
I bought the power supply as a replacement for Seasonic Focus GM 650 Gold. The old power supply had not quite suitable overall performance for the new GPU (AMD Radeon RX 9070 XT), but mainly it did not have 0 RPM mode (i.e. no fan speed operation) and the fan was already knocking. Normally it was barely audible, but when recording vocals/acoustic guitar with a condenser microphone, you could hear it in the background.
The new power supply is completely silent (reviews say up to about 400-420 W load) without the fan running.
I personally didn't notice the fan even during the stress tests of the new GPU (Steel Nomad from 3DMark. GPU consumption 334 W, CPU consumption approx. 60W), but it is true that it is already slightly audible GPU, CPU and case fans and I did not visually check the power supply fan itself. So the large fan (14 cm diameter) may have turned very slowly, but it was not audible.
THIS (the main reason for the acquisition).
Large fan that rotates very slowly under load (14 cm diameter).
Long-term reliability and high quality (this model has been on the market for a long time and there are many detailed reviews and user experiences).
Trcho more expensive than the competition (but again, quality and reliable).

Corsair is such a quality brand where you go for safety and even this time did not disappoint. It runs quietly, has a 12 pin connector for new graphics and I think the cables are great. Most power supplies have stiff cables that are difficult to bend and handle. Braided cables are great and it just takes a few strips to keep them from traveling everywhere. Manual - auto adjustment via a knob on the rear is also a nice feature. It would just be good if one could read about it somewhere in the manual and not have to google it.

auto or manual mode on the fan (but always switches on automatically if needed to avoid overheating)
