Its fully modular design and ease of installation are also frequently praised, simplifying cable management and the overall building process. While some users noted its larger size, the positive feedback overwhelmingly focuses on its reliability and value. The power supply is considered a great option for its price point.

    I have had the power supply for a tad bit over 1 year now and it is still working perfectly. It has been through multiple power surges/outages and as far as I can tell is still perfectly functioning. Great quality Power Supply & Cables.

    I feel like this PSU is faster than my previous PSU by GIGABYTE. Corsair is a pretty reliable brand so I am glad they did not disappoint when I plugged this PSU. The Power OFF/ON switch seems to shut-off/turn-on the RGB lighting almost instantly. With my GIGABYTE PSU (That got recalled) it had a small noticeable delay when powering on the system.
