About Corsair CP-9020177-UK RM550x 80 Plus Gold 550 W Fully Modular ATX Power Supply
Overall Feedback:
82% positive
82% appreciated the cooling mechanism
I am impressed with the cooling mechanism of the internal-power-supplies as it boasts of a zero RPM mode and I don't even know it's there.
My entire PC is running much cooler after fitting this PSU.
79% highlighted the modularity
The modular design of our internal power supply makes it easy to install.
The power supply has plenty of modular cables, allowing me to install only the ones I need. It's fairly simple to install and all the cables are long enough to stretch to where they're needed, even on a big case like HAF-X.
The modular aspect is excellent, allowing me to connect the case tidily.
The power supply is completely modular, so I only need to plug in the required cables to power the installed kit.

79% liked the power output stability
I found no voltage problems and the product is overkill for my system.
If the power drain is below 300W, our PSU fan does not run.
I have experienced that the PSU stays below 12 Decibels until around 550 Watts and then increases to 25 Decibels at maximum power draw.
After installing the new power supply, my PC runs completely stable with no crashing at all.

83% found the operations silent, while 17% experienced weird noises
I made sure to get more wattage than required so that the PSU always works at less than half of its capacity, ensuring cool and quiet operation in semi-passive mode.
I bought the PSU for the zero fan silent mode and it has performed beautifully.
The fan I have is the quietest I have ever used.
The power supply operates silently and the fan only spins when necessary.

74% appreciated the efficiency rating
The fan runs almost silently even at temperatures around 30 C and less than 80W power. The rated figure of 18 db seems credible.
I bought an 850w PSU with excess power because I had heard that they are not as efficient as stated, but with this product, that is not the case.
The power supply is performing excellently and I am impressed with it. The fan starts at about 40 degrees C.
The power supply has a high efficiency rating, resulting in less heat, fan use, and noise.
