So far so great. Super quiet and modular.

Great PSU for the money and at this wattage. I have had zero problems with it and have been using it daily for the past 3.5 years. Recently upgraded to a higher wattage PSU but this will be used in another system and I have zero concerns. This will not blow up your system, nor will it catch on fire, even if people try to convince you otherwise.

Brilliant PSU, well built from Corsair with wired CPU and 24pin ATX. ATX cable is sleeved except for the last 2 inches or so, but some heatshrink or electrical tape can remedy that if you are concerned about seeing the unsheathed cable.

More than enough power for single GPU setups.
